Adhesive label meaning
The adhesive is a kind of material, also called self-adhesive label, pressure-sensitive label, etc.
It is made of paper, film, or special material, coated with adhesive on the back and coated with silicon bottom paper as protection paper.
After the self-adhesive material is processed by printing, die-cutting, etc., it becomes a finished label.
Different from traditional labels, in the process of using self-adhesive labels, there is no need to brush glue, no need to paste, no need to dip it in water, which can save the labeling time;
And the adhesive label does not pollute the environment, it is an environmentally friendly product.
In addition, the application range of self-adhesive labels is very wide, and it is an important medium for various types of product promotion.
What is adhesive sticker?
An adhesive sticker is actually a type of label, and the front and back sides of the adhesive sticker are made of different materials.
The front material types include plastics, printable base paper, etc.; the back is coated with pressure-sensitive adhesive.
Adhesive stickers are often used by people to decorate walls or other places that need beautification.
The color, shape, and design of the sticker can be customized to meet your different decoration needs.
Self adhesive label
Self adhesive label is mainly composed of three parts: face material, glue, and release liner.

Adhesive label printing machine
China’s adhesive label printing industry: there are many small and medium-sized printing plants, and there are few specialized large-scale printing plants;
Printing plants have many primary types of equipment and a few high-end types of equipment.
The adhesive label printing market has developed unevenly: coastal areas are developed, followed by central areas, and inland areas are relatively backward.
In terms of adhesive label printing, letterpress printing is the mainstay.
Continuous paper feeding is the most advanced printing form, followed by reciprocating paper feeding, intermittent paper feeding is the most basic and lowest precision paper feeding method.
Sheet-fed label printing is a unique processing method in China, which is rarely seen abroad.
The printing level of domestic adhesive labels is only in its infancy, which is far from the advanced level in the world.
Not only in printing equipment, but also in the design of printing processes, printing materials, and labels.
1. Letterpress adhesive label printing equipment
The main letterpress self-adhesive label printing equipment manufacturers include Japan’s Ko-Pack and the Japanese wholly-owned company Shanghai Xinmin Taiyang.
Domestic Shaanxi Beiren Company’s self-adhesive label printing equipment is also on the market.
China’s domestic adhesive label printing equipment is satellite-type continuous paper printing machine, configured for 6-color UV letterpress printing and a set of UV coating;
Optional rotary die cutting, flat die cutting, corona treatment, and single sheet collecting can be added.
In order to ensure the accuracy of UV coating, both Ko-Pack and Xin Min Taiyang changed the traditional roller coating to flexographic coating.
The varnish coating amount is determined by the anilox roller lines number and is not affected by pressure and printing speed, ensuring the consistency of printing gloss.
Rotary flattening intermittent paper-feeding label printing equipment is also common equipment for label printing.
The main manufacturers are Japan Sanjo, Lindeco, Taiwan Wansheng, Luotie, Chuanling, Shenzhen Zhengqi, Guangzhou Haotian, Naimoto, and Ruian Zhongtian, and so on.
The main transmission mechanism of the equipment is changed from traditional mechanical transmission to electromechanical integrated shaftless transmission.
The paper feeding length can be preset by the computer, and the roller can automatically pull the material and convey the paper, which completely eliminates mechanical errors.
Another significant change is the installation of a UV drying device and the use of UV inks, which expands the label printing range, increases the printing speed and eliminates the laminating process.
2. Flexographic label printing equipment
This type of equipment is all narrow-width flexo printing machines, mainly domestic products, such as Shanghai Ziguang, Xi’an Black Bull, Wuxi Baonan, etc. The equipment has two characteristics:
①Use UV ink instead of water-based ink. UV ink has good stability and avoids frequent cleaning of the printing plate and inking system.
More importantly, the color density of UV ink is greater than that of water-based ink, which can improve the printing quality of labels.
②The direct laser plate-making technology without film is widely used, which avoids the loss of small dots and the parallelization of large dots, improves the image level, and greatly improves the clarity of graphics and printing.
Flexographic printing self-adhesive labels are the future development direction.
At present, domestic companies adopt domestic components and foreign technology to produce flexographic printing equipment.
3. Die cutting equipment
There are two printing and processing methods for self-adhesive labels: one-step, that is, printing and die-cutting are completed at one time.
One end of the machine inputs the raw materials and the other end comes out the finished label, which is suitable for simple label production;
Step-by-step, that is, label printing and die-cutting are performed on two equipment, which is suitable for label production with complex graphics and text, multiple procedures, and batches.
Step-by-step processing can reduce costs, reduce waste, and improve efficiency.
①Roll-feeding rotary die cutting machine
This type of die-cutting machine can not only process printed self-adhesive label roll materials, but also directly die-cut blank labels and folds, or cut single sheets, with high efficiency and precision.
②Single-sheet paper die-cutting machine
Self-adhesive labels printed on a single sheet of paper currently account for 10% in the China market.
All these products are die-cut on a flat-bed manual die-cutting machine.
A flat-bed manual die-cutting machine is not suitable for self-adhesive materials, such machine has high labor intensity and low production efficiency, poor die-cutting quality.
As a large label producer, China is also the greatest potential market for label printing.
In the future, self-adhesive label printing will develop in many ways, and label printing plants of various business scopes and processing types have their own development space.
The future label printing equipment market will be very prosperous, new equipment will gradually replace old equipment, and printing technology and processes will coexist in multiple forms.
Adhesive label printing company
There are many adhesive label printing companies, such as Nova Label Company, Focus Label, Uprinting, CCL Label.
Of course, there are still many other label printing companies that are not listed here, you can search for them on Google, Bing, or other search engines.

Label die cutter
Compared with the previous tie-rod die-cutting machine and the most primitive punching machine, the modern label die cutter has a faster speed, full touch screen operation, more convenient operation, higher precision, and higher production efficiency.
The flat die-cutting machine adopts punching up and down, using a cutting die to punch the label into a certain shape.
The main parameters of the label die cutter are: model, die-cutting speed, maximum unwinding diameter, maximum unwinding width, maximum die-cutting width, maximum die-cutting length, positioning accuracy, total power, power supply voltage, overall dimensions, machine weight.
High-precision die-cutting, driving, and sheeting are controlled by computer.
Both sides and longitudinal direction printing marks are accurately tracked and positioned by three photoelectric sensors.
Die-cutting, laminating, waste collection, and sheeting are automatically completed in one time.
It is very suitable for die-cutting paper sticker trademarks, polyester film trademarks, and laser anti-counterfeiting trademarks.
Self-adhesive label die-cutting machine is the best supporting equipment for flexo printing machine, screen printing machine, and rotogravure printing machine.
Rotary label die cutting machine
The rotary die cutting machine is a cutting machine, which is often suitable for mass cartons or labels production.
The rotary die cutting machine’s magnetic roller continuously rotates when it is working, and its productivity is also the highest among all types of die cutting machines.
However, the die-cutting plate of the rotary die cutting machine has to be bent into a curved surface, it is troublesome to make a plate.
Generally, a product consumes a cutting die, and the cost is relatively high.
There are certain difficulties in equipment technology, so the rotary die cutting machine is often suitable for mass production.
The die-cutting method of the rotary die cutting machine is generally divided into two types: hard cutting and soft cutting.
The hard cutting method means that the knife is in hard contact with the pressure roller surface, so the die cutting knife is easier to wear;
The soft cutting method is to cover engineering plastic on the pressure roller surface.
When die cutting, the cutter can have a certain amount of cutting, which can protect the cutter and ensure complete cutting, but the plastic layer needs to be replaced regularly.
Digital label die cutting machine
The modern printing industry usually includes three processes: pre-press, printing, and post-press.
Post-press processing is usually divided into books and magazines processing and package processing.
The die-cutting machine is modern post-press processing equipment.
It is widely applied for die-cutting, creasing, and cold embossing of trademarks, cartons, greeting cards, etc. in the paper packaging and decoration industry.
The traditional die-cutting plate-making process is complicated, time-consuming, energy-consuming, and poor in operational flexibility.
Digital die-cutting (or plateless die-cutting) has changed the die-cutting process’ dependence on the printing plate, reducing energy consumption and pollution.
Label printing and cutting machine
Label printing and die-cutting can be done on one machine simultaneously, you can use a flexographic printing machine with die-cutting station, or use a printing die-cutting integrated machine.
You can search for label printing and cutting machine on Youtube, then you can view such a machine’s demonstration video.
Through the demonstration video, you can get an overview of the label printing and cutting machine’s general working process.
Label die cutting machine price
In the Chinese market, the label die cutting machine’s price varies from supplier to supplier.
Low-end models cost as low as $2,800, and high-end models cost $35,000.
Which brand of label die cutting machine is good?
Speaking of label die cutting machines, there are several well-known manufacturers in the world that produce such machines, such as:
GRAFOTRONIC AB from Sweden, Daco Solutions Limited from the UK, Preco, Inc. from US.
Relatively speaking, above European and American brand label die cutting machines’ quality is very good.
Label die cutting machine operation guide
1. Operation regulations before starting up
(1)Check the handover records to understand the machine operation status.
(2)Check records, check die usage, and check stock.
2. Operating regulations in working
(1)Select the die, and fix the die and bottom plate on the die cutting machine.
(2) Adjust the die cutting pressure.
When adjusting, the pressure should be gradually increased from light to heavy to 80%, otherwise, it will cause equipment damage.
(3)After adjusting the die-cutting machine, perform punching in accordance with the requirements.
And then send the first piece to quality assurance inspection, and normal punching can be performed after confirming the qualification.
(4)During the production process, sampling inspection should be performed every 30-60 minutes.
Quality problems should be reported in time, and production can be continued after resolution.
3. Operation regulations after finishing
(1)The captain should fill in the die usage records and die-cutting machine equipment inspection form every day.
(2)Separate the die-cut products into qualified and defective products, and clearly identify them.
(3)Maintain the equipment according to the daily maintenance content.
(4)Turn off the power and clean the machine.
(1)Check the die and die usage records, if find any die is abnormal or any die is used beyond the service life, put them forward in time.
Check the inventory. If the inventory has material preparation, first consider using the inventory balance.
(2)Check whether the part number on the drawing is consistent with the customer part number on the die box, and check whether the die part number on the die box is consistent with the part number on the die.
After checking, machine running is allowed.
(3)Before adjusting the die, the pressure should be reduced first, avoiding damage to the equipment due to excessive pressure.
(4)Do the first piece inspection (the captain’s self-inspection, quality assurance inspection), and perform random inspections at work (the captain does random inspections and quality assurance inspections regularly).
(5)When the captain is using the die-cutting machine, be careful not to put his hands in the place with the “yellow label (beware of hurting hands)” to avoid accidents.
(6)When the die cutting machine is working, do not let objects block the sensor.
Label die cutting machine die adjustment method
In the actual die-cutting production, the die adjustment in the die-cutting machine is particularly important.
The correct position of the die directly affects the production efficiency and product quality, and may even cause safety accidents.
In actual production, the die adjustment of the die cutting machine mainly has the following functions:
1) Ensure safe production without affecting the quality of finished labels;
2) Adjusting the die is essential to ensure normal start-up operations.
If the die is not adjusted properly, all die-cutting operations will not be carried out;
3) Adjust the die to avoid producing defective products and wasting materials;
4) The die adjustment helps to improve production efficiency;
5) Good die adjustment habits are beneficial to protect the equipment die base from loss, improve equipment utilization, and extend equipment service life.
Several basic steps of die cutting machine’s die adjustment:
(1) Die claim
According to the drawing and material number, claim the die.
In the process of the die claim, the die number must be correctly compared in order to claim the die correctly, it cannot be judged by the product shape.
In large die-cutting factories, there are too many dies with similar shapes, and the same product’s dies are also divided into new and old ones.
Once claim the wrong die, it will be discovered during production, but after discovery, it has caused a large waste of materials.
(2) Fix die
After die claim, we need to fix the die on the die cutting machine.
When fixing, we need to strictly compare the work instructions, confirming whether the die is a down punching die or an up punching die.
If it is an up punching die, the die needs to be fixed on the lower die plate;
If it is a down punching die, you need to fix the die on the upper die plate.
When fixing, we usually use double-sided tape with higher viscosity and thinner thickness for fixing, prevent the die from falling off during the punching process.
(3) Angle adjustment of the fixed die
Not only is it necessary to fix the die.
During the fixing process, we must ensure the verticality of the die and the feeding direction of the machine, ensures that the die is vertical to the feeding during punching.
(4) Fixing the backing plate
After fixing the die, we need to fix the backing plate.
The backing plate’s main function is to protect the direct contact between the die and the die plate, reduce the damage of the die, and increase the die’s service life.
The backing plate generally adopts a PVC board or PE insulation board, board thickness is about 1mm.
(5) Die-cutting pressure adjustment
The pressure adjustment here mainly refers to the die cutting depth adjustment.
After we have installed the die header, we need to adjust the die header to test the pressure, check whether the die can effectively punch the material.
During the pressure adjustment process, it is strictly prohibited to directly perform single-action or linkage punching, and the equipment must be adjusted to the manual gear for test adjustment.
When the die header is adjusted to the current maximum stroke and still fails to punch the material effectively, the pressure adjustment should be carried out and tested again.
When the die header is adjusted to the maximum stroke and has been punched to the lower die base, it indicates that the die header’s pressure is too deep, and the pressure should be reduced for another test.
Note: In the process of adjustment, we should try our best to adjust the stroke in the smallest unit, and it should not be too large.
(6) Fine adjustment of die flatness
When the die pressure is adjusted to the extent that the die can fully die-cut, but there are still some subtle places that do not meet the punching requirements, it is necessary to fine-tune the flatness of the die.
Usually, in the fine-tuning process, we need to use carbon paper.
Place the carbon paper between the backing plate and the die, and then perform die cutting, leaving the carbon paper imprint on the backing plate, and then compare the punched sample with the imprint on the die.
Where the punching is too deep, we need to use a small blade to scrape the die;
When the punching is too shallow and cannot be effectively punched, we need to cover the shallow area with tape or other materials to raise the die, ensures that the die can effectively punch.
In the process of fine-tuning the flatness, whether we are scraping or covering, we must adjust in the smallest unit.
Our commonly used cushion material is 0.025mm OPP, and other thinner materials can also be used.
(7) Die angle adjustment
After we complete the above steps, we can perform the first continuous punching.
However, in the process of continuous punching, we found that the product is not completely vertical to the feeding direction, especially when punching, there are errors in the matching cutting lines of the front and rear knives.
This is because when we adjust the die, the die is not completely vertical to the material feeding direction.
At this time, we need to adjust the vertical angle of the die.
At present, most of the machines on the market no longer need to adjust the die’s vertical angle, but only need to fine-tune the die header on the equipment to adjust the die angle.
Label die cutting machine inaccurate positioning
Die cutting distance refers to the distance between 2 labels after the die cutting waste is discharged.
Under normal circumstances, the die-cutting distance of the self-adhesive label is between 2-3mm.
In daily production, we often encounter the phenomenon of inaccurate die-cutting spacing, which is mainly reflected by the fluctuation of the spacing.
Such label products also do not meet quality standards. So, what is the cause of this phenomenon?
1. The printing cursor spacing is not accurate
During the die-cutting process, the size of the gap is determined by the die-cut cursor printed in advance during printing.
However, during the printing process, some devices have a slight error in the printed cursor spacing, which in turn leads to inaccurate spacing during die cutting.
Such a situation is usually reflected as a slight error between the label spacing, and sometimes the label spacing will gradually increase or decrease with periodicity.
If you encounter this kind of problem, the die-cutting process cannot be solved, you may have to find the cause of the error during printing and start to solve it.
2. Die-cutting machinery problems
As mentioned earlier, the printing cursor usually needs to be tracked during the die-cutting process.
Then, if there is a problem with the photoelectric sensor, the die-cutting distance will also be inaccurate.
In this case, you can try to adjust the photoelectric sensor again according to the operating procedure or restart the photoelectric sensor after turning off the machine.
If the problem is not resolved, you need to consider replacing the photoelectric sensor of the die cutting machine.
3. Material deformation
Many film-type self-adhesive materials will shrink and deform due to the heat of the UV lamp during the printing process.
Such materials are also prone to inaccurate spacing during the die cutting process.
When encountering such problems, you can first measure whether the actual spacing of the printed cursors is smaller than the designed spacing.
If it is judged that the spacing is incorrect due to this problem, it must be controlled during the printing process.
We can reduce the chance of thermal deformation of the material by reducing the UV lamp power or increasing the printing speed.
Label die cutting machine error
1. The influence of die-cutting equipment on punching accuracy
The influence of material feeding.
If the material feeding controlled by the motor isn’t accurate according to the specified step, the position of the die cutting will be uneven.
2. The influence of dies on punching accuracy
In the actual die-cutting process, the shape of the die directly determines the shape forming of the die-cut part.
Although the shape and size of the die are produced according to the requirements, the dies we produce do not fully meet the size requirements of the designed drawings.
Then, since the dies cannot be produced absolutely in accordance with the size requirements of the drawings, it is also impossible to punch out die-cut parts that absolutely meet the size requirements.
3. The influence of material on punching accuracy
In actual production, the difference in material thickness and characteristics will affect the punching accuracy.
For example thicker soft materials, foam materials, etc., such material is deformed during punching.
At this time, the size of the punched product will definitely not be the desired size, obvious tolerance exists.
For another example, a relatively smooth material, because of its smoothness, is prone to slip.
The products punched out in this way will also have tolerances due to slippage of the material.
4. The influence of die-cutting process on punching accuracy
There are too many uncertain factors that affect the accuracy of die-cutting in the die-cutting process because the different punching methods involve different equipment, material combinations, which directly affect the punching accuracy.
In the die-cutting process, the most direct factor that affects punching accuracy is the tolerance caused by the matching of the front and rear strokes.
At present, in order to avoid this problem, the industry generally adopts the method of small hole-nesting, and at the same time, it is convenient to carry out the nesting operation and production.

What is a rotary die cutter?
The rotary die cutter includes a magnetic die-cutting roller and a pressure roller.
In the working process, the NIP roller sends the label between the magnetic die-cutting roller and the pressure roller, and the label is clamped by the two, die-cut by the magnetic roller.
The magnetic die-cutting roller rotates 1 circle, complete a work cycle.
Because of this, rotary die cutter’s production efficiency is the highest among all kinds of die cutting equipment.
Therefore, the rotary die cutter is particularly suitable for mass production.
At present, most advanced die-cutting equipment is developing towards the fully automatic combination of printing and die-cutting, that is, organically combining die-cutting machinery and printing machinery.
This type of production line usually includes a feeding unit (or called a feeding part), printing unit (or called the printing part), the die cutting unit (or called the die cutting part), and the collecting unit (or called the collecting part), realizes high-speed continuous production.
However, the above-mentioned rotary die cutter’s functions are not perfect and have considerable limitations, which need to be further improved.
Small rotary die cutting machine
For the rotary die cutting machine, according to the different die cutting objects, it can be divided into cardboard rotary die cutting machine, label rotary die cutting machine, etc.
The small rotary die cutting machine generally refers to the rotary die-cutting machine for self-adhesive labels, because this type of machine is usually small in size, and the unwinding width is generally only 320mm or 420mm, which is very small.
Rotary die cutter for corrugated
Rotary die cutter for corrugated is composed of three parts, namely die-cutting part, material feeding part, and electrical control part.
As for the die-cutting part, soft cutting is currently used. The soft cutting means to put a layer of high-strength polyurethane rubber sleeve on the roller, which is mainly beneficial to protect the die’s service life.
The advantages and characteristics of the rotary die cutting machine are that the die cutting speed is fast, the speed can reach 140 pieces per minute, and the die cutting accuracy is high, which can be controlled within +/-1mm.
At the same time, the rotary die cutting machine has the advantages of simple operation, moderate price, and long service time.

Advantages and disadvantages of rotary die cutter
1. The biggest difference between the rotary die cutter and the flat die cutting machine lies in the different dies.
2. Die-cutting methods are different: the rotary die cutter adopts the roller method for die-cutting, and its principle is the same as that of a car tire, and one product is rolled once;
While the flat die-cutting machine uses the traditional die-cutting method, that is, the die is up and down, die-cutting is realized by punching.
3. Most of the rotary die cutter adopts the combination of man and machine, and adopts the full servo drive system, which is quick for novices;
While the flat die-cutting machine requires manual waste removal, which takes a long time and is relatively inefficient.
4. The rotary die cutter is suitable for large-scale production and has relatively high efficiency; while the flatbed die cutting machine is suitable for small-scale production and covers a large area.
5. The rotary die cutter is suitable for cooperation with long-term customers, while the flatbed die cutter is suitable for short-term customers.
Because the rotary die cutter’s die is more expensive, it is too wasteful to use it once, so it is suitable for long-term customers.
6. The rotary die cutter is more expensive than the flat bed die cutting machine, but the die cutting accuracy of the rotary die cutting machine is not as high as that of the flat die cutting machine.
7. The rotary die cutter requires low labor cost, and the flat die cutting machine requires high labor cost.

How to adjust the rotary die cutter’s knife
Preheat and keep warm
Before the official start-up, preheat the rotary die cutter’s die; when it is not in use, it will be kept warm.
Pressure relief and pressurization
In the initial use of the rotary die-cutting die, according to the die manufacturer’s recommendations, when the die is not used for a short time, the pressure should be released;
When it is used again, it needs to be re-pressurized and adjusted to the appropriate pressure.
Maintaining the correct die spacing is the key to ensuring the die cutting quality and die life maintenance.
Under the condition that other parts are in normal use, the author adjusts the spacing of the rotary die cutter’s die as follows.
(1) Use imported carbon paper to adjust the gap between the upper cutting line of the die and the pressure roller.
If it is completely cut through, the die cutter blade of the upper roll may hit the pressure roller.
(2) The gap between the die cutting line and the pressure roller must all meet the above requirements.
If the gap is too large, a thin steel sheet with a thickness of 0.003mm must be used to adjust one by one;
if the gap is too small, professional tools can be used to properly grind the die cutter.
Adjustment and maintenance
When the rotary die cutter’s die runs about 1 million revolutions, the machine stops, the die is unloaded, and the die is inspected, adjusted and maintained.
Tests have proved that this solution not only guarantees the die-cutting quality of the label but also guarantees the service life of the rotary die-cutting die.
During the adjustment and maintenance of the rotary die cutting die, the spare die can be put into use.
According to the actual production experience, the rotary die cutting die will be reground as a whole every time it runs about 12 million revolutions, and the maintenance effect achieved is better.
How many cuts/h of rotary die cutter
For the rotary die cutter, the speed is not measured in cuts per minute, but in meters per minute.
The fast rotary die cutting machine can reach a speed of 300 meters per minute.
Rotary die cutter operation guide
Rotary die cutter’s operation is similar to flatbed die cutting machine, the only difference is the cutting die registration and replacement.
Rotary die cutter’s die needs to be installed on a magnetic cylinder, while flatbed die cutting machine’s die needs to be fixed on a plate.
Once you ordered a rotary die cutter from us, we will share a rotary die cutter operation guidance video with you for reference.
