Our Business: Flexible Materials & Advanced Composites

JOTA Machinery was founded in 2008, initially focusing on roll-to-roll converting equipment and solutions for paper and other flexible materials.

In 2011, we established our own manufacturing facility and expanded our capabilities in slitting and rewinding, die-cutting, sheeting, and flexographic printing.

In 2015, JOTA relocated its manufacturing operations to Kunshan, Jiangsu, close to Shanghai and the manufacturing supply chain of the Yangtze River Delta.

Today, our manufacturing capabilities include in-house CNC machining, machine assembly, testing, and engineering support, giving our team greater control over critical machine components and the manufacturing process.

JOTA now serves two core application areas: flexible material converting and advanced composite materials.

Across both areas, our focus is on roll-to-roll and roll-to-sheet processing technologies, with equipment configured around the customer’s material, process requirements, and finished-product specifications.

Our business in the flexible packaging sector can be divided into the following 4 categories:

What is Slitting?

Slitting refers to the process of unwinding jumbo rolls of raw material, passing them through transition rollers and slitting knives, and finally rewinding them into smaller rolls.

Common products like BOPP tape, toilet paper rolls, and industrial stretch wrap films are produced using slitting machines.

Jota Machinery’s slitting products include the 3 mainly range:

Thermal paper is a special type of printing paper coated with chemicals that change color when heated, eliminating the need for ribbons or ink.

Thermal paper can be BPA-free or contain BPA.

Typically, thermal paper rolls sold online are in smaller widths like 56mm and 79mm, whereas raw materials are usually 500-700mm width, with some European standards exceeding 1100mm. Therefore, our thermal paper slitting machines come in standard widths of 900mm, 1100mm, and 1400mm.

Thermal paper is widely used in POS systems such as cash registers, ATMs, medical ECG paper, and lottery tickets thus attracting many entrepreneurs to this industry.

However, newcomers often lack experience and funds, making thermal paper roll business planning challenging.

We offer comprehensive services, including raw materials, warehouse leasing suggestion, consumables, and technical support, providing a one-stop solution.

Adhesive labels sticker are also common in the flexible packaging industry, often requiring printing and die-cutting processes to meet customer needs.

The production process starts by slitting jumbo rolls of around 1270mm into 320mm or 420mm widths.

For colorful labels, flexographic printing is used to print patterns on adhesive labels.

Jota Machinery offers 2/3/4/6-color printing solutions.

The printed jumbo rolls are then processed through die-cutting machines to complete the label production.

Our JT-SLT-1300F slitting machine, FPT flexographic printing machine, and die-cutting machine can provide customers with a complete production solution.

 What is sheeting?

Sheeting involves cutting roll materials into sheets using a slitting knife followed by a cross-cutting knife. For example, an 80gsm A4 paper roll (1050mm wide) is first slit into 210mm wide strips, then crosscut into 297mm long sheets to complete the cross-cutting process.

Sheeter machines are suitable for various materials like sandwich wrapping paper, hamburger paper, greaseproof paper, and cigarette paper. For thin materials (10-20gsm), Jota Machinery offers double-layer sheeting machines to ensure high-speed operation.

With global warming and increasing environmental concerns, the use of paper products to replace plastics is growing. Products like paper drinking straws, kraft paper tape, and paper bags are becoming more common.

In 2017, an Indian client introduced Jota Machinery to the kraft paper tape slitting industry.

Before the development of dedicated kraft paper tape slitting machines, many clients used double-shaft slitting machines.

These traditional machines required manual attachment of tape to rewinding paper cores and manual removal from the rewinding shaft. The whole process is cumbersome and time-consuming.

Our self-adhesive kraft paper tape slitting machine is an intelligent machinery developed from thermal paper slitting technology.

It uses a single rewinding shaft and can produce both coreless and cored tape.

With an automatic tucker and water spraying system the production efficiency can increase by up to 200%.

After rewinding, the machine uses a limit switch to push the shaft to a conveyor. For customers with packaging needs, we can also add heat shrink film packaging machines.

The kraft paper tape slitting and packaging line has been successfully delivered to our German clients. Contact us for more information about this production line.

What is a CAD Drawing plotter Paper Slitting Machine?

The CAD drawing plotter paper slitting machine is a high-speed device developed by Jota Machinery.

The slitting machine can cut jumbo rolls of 80gsm paper into widths ranging from 297mm to 1524mm and rewinding onto 2-inch or 3-inch cores, with roll lengths of 50m, 100m, and 150m. 2-inch plotter paper rolls are used for plotters, while 3-inch rolls are for engineering printers.

Our plotter paper slitting machine features a hydraulic shaftless unwinder. The max jumbo roll weight can bear is up to 1000kg.

In modern industrial production, hydraulic shaftless unwinders are becoming essential, providing a reliable solution for handling large rolls without traditional shaft support.

The hydraulic system allows precise control of unwinding speed, tension, diameter, and tightness. The high precision enhancing production efficiency and ensuring consistent quality.

In terms of environmental protection and safety, the hydraulic shaftless unwinding stand also has advantages.

The hydraulic system is used for coil control, which makes the operation process more stable and safer, reducing the risk of manual operation.

At the same time, by reducing the use of internal support shafts, it can also effectively reduce material waste, meeting the high standards of modern industry for environmental protection and resource utilization efficiency.

The 2024 model of our plotter paper slitting rewinding machine offers fully automated production, including automatic core loading, knife positioning, shaftless rewinding, and automatic packaging.

The automatic knife positioning system is linked to PLC programming. You only need to input the required slitting width on the HMI interface and an automatic robotic arm will function, allowing you to adjust the slitting size more accurately.

Beyond our flexible packaging slitting business, we also provide advanced composite materials services for industries like aerospace automated fiber placement or automated tape laying, new energy hydrogen storage and automotive manufacturing.

Our offerings include continuous fiber reinforced thermoplastic UD prepreg machine line, Teflon double-belt press machine, thermoset carbon fiber prepreg machine, and prepreg slitting machine.

The hot-melt impregnation method is the basic procedure for continuous fiber-reinforced thermoplastic（CFRT） prepreg tape production.

Continuous carbon or glass fibers are evenly fed through a fiber spreading system into the impregnation mold, where high-performance resin is extruded by a twin-screw or single-screw extruder. The impregnated prepreg tape after cured, cooled, and rewinding into uni-directional (UD) tape.

UD tape needs to be processed by slitting and roll to sheet cutting machines for use. Jota Machinery serves clients in the oil and gas transportation pipeline and thermoplastic composite sandwich panels industries.

For petroleum industry transportation RTP/TCP pipelines, we offer thermoplastic glass fiber-reinforced PE unidirectional tape.

RTP pipes have outer protective, reinforcement, and inner liner layers, with the reinforcement layer made of multiple layers of glass fiber tape.

The width of the glass fiber unidirectional tape used is 45-300mm. It can be assembled into an RTP pipe production line through our UD tape slitting machine.

Another application of thermoplastic unidirectional tape is in sandwich panels combined with PP honeycomb cores also called pp thermoplastic honeycomb sandwich panel. These lightweight, high-strength composites sandwich panels can replace aluminum honeycomb panels.

Our Teflon double belt press machine supports the production of thermoplastic laminated sheet by continuous heating and cooling.

Thermoplastic honeycomb sandwich panels consist of two outer skins and a core layer (foam or honeycomb).

The skin is produced by laminating PP unidirectional tapes at 0°, 45°, and 90°. The laminated sheet can be combined with the core layer without hot melt adhesive to obtain an eco-friendly production process.

Composites sandwich panels are used in refrigerated containers, electric vehicle battery panels, furniture, and more.
