A new paper machine reaching 1,400 m/min is impressive.

Reaching that speed 10 days after startup is arguably more important.

Voith has started up Sun Paper’s new PM47 packaging paper machine at the Yanzhou production site in Shandong, China.

The machine has an 8.66-meter wire width, annual design capacity of 700,000 tonnes and maximum operating speed of 1,400 m/min. According to Voith, PM47 reached 1,300 m/min during its first week and its maximum operating speed only three days later.

From the start of civil construction to first reel, the project took just 11 months and eight days.

Those figures make PM47 a notable engineering achievement.

But the more interesting industrial lesson is:

A paper machine’s economics are determined not only by how fast it can eventually run, but by how quickly it can move from construction to stable commercial production.

A 700,000-tonne machine makes slow ramp-up expensive

Large packaging machines require enormous upfront capital.

Once installed, the owner wants to turn that capital into saleable tonnes as quickly as possible.

A 700,000-tonne annual design capacity corresponds to roughly 1,900 tonnes per calendar day at theoretical full-year output.

Of course, actual production depends on maintenance, grade mix, efficiency and other factors.

But the scale illustrates why commissioning matters.

If a machine of this size spends months running substantially below target speed, the economic impact can be considerable.

That is why PM47’s rapid ramp-up deserves more attention than the headline speed alone.

Voith says the machine produced its first paper only four days after installation of the final equipment, before reaching full operating speed six days later.

That compresses one of the riskiest phases of a major paper investment.

Full-line integration may have helped reduce startup complexity

Voith supplied much more than the paper machine itself.

Its scope included:

• OCC stock preparation;
• an UKP virgin-fibre system;
• wet-end process systems;
• the paper machine from headbox to reel;
• MCS and QCS automation;
• OnCare.CM condition monitoring;
• and the MillOne production-data platform.

This matters because startup problems do not respect equipment boundaries.

A new paper machine can be mechanically ready while stock preparation is unstable.

Stock preparation can perform correctly while wet-end consistency control is not tuned.

The machine can run fast while quality variability prevents saleable production.

By integrating fibre preparation, machine controls, quality measurement and production data, a full-line project can potentially reduce some of those interfaces during commissioning.

That does not prove that one-supplier projects will always start faster.

But PM47 demonstrates the potential value of integrating more of the process before startup rather than solving interfaces after individual systems arrive on site.

The OCC line shows the scale behind the paper machine

PM47’s stock-preparation system is itself a major installation.

Voith says the OCC line is designed for 2,200 tonnes per day, placing it among the highest-capacity OCC systems in Asia.

It uses an IntensaPulper designed for very large-volume low-consistency pulping.

That capacity is significant because high-speed packaging-paper production begins long before the headbox.

If recovered-paper preparation cannot continuously provide sufficiently clean, stable pulp, a 1,400 m/min paper machine has little opportunity to demonstrate its potential.

Large packaging-paper machines therefore increasingly require equally industrialized recovered-fibre systems.

The raw-material line has to deliver:

stable consistency,

contaminant removal,

reliable throughput,

and predictable furnish quality

at nearly continuous operating conditions.

In that sense, the OCC plant is not auxiliary equipment.

It is part of the machine’s production capacity.

Energy efficiency also begins in stock preparation

Voith says permanent-magnet motors have been used extensively through PM47’s stock-preparation process to reduce drive energy consumption.

That is worth noting because modern paper-machine efficiency is increasingly being optimized beyond the dryer section.

Pulping, screening, pumping and stock preparation all consume electricity.

When a mill processes thousands of tonnes of furnish every day, relatively small improvements in specific energy consumption can accumulate into meaningful annual savings.

For a new 700,000-tonne line, the commercial target is therefore not simply maximum tonnes per hour.

It is producing those tonnes with competitive:

energy,

fibre,

water,

maintenance,

and labour intensity.

PM47 is part of a wider capacity build at Yanzhou

Sun Paper’s own 2026 half-year reporting confirms that the 700,000-tonne high-grade packaging paper project entered production in August 2026.

The company has also been developing a 600,000-tonne bleached chemical pulp project at the same Shandong base, including chemical recovery, waste-heat power generation and chlorine-dioxide preparation systems. Earlier company reporting scheduled that pulp project for trial production during the third quarter of 2026.

That wider context matters.

Sun Paper is not adding an isolated paper machine.

It is expanding both paper production and upstream fibre capability.

This can provide greater control over:

furnish availability,

fibre quality,

production cost,

and the balance between recovered and virgin fibre.

PM47 therefore sits inside a larger integrated manufacturing strategy.

The finishing equipment also has to keep up

There is little value in running the paper machine at 1,400 m/min if downstream equipment becomes the next bottleneck.

The PM47 project includes two Andritz PrimeE-Wind rewinders, each with an 8.66-meter working width and design speed of 2,500 m/min.

The rewinders include automated roll change, core feeding, core gluing, tail gluing and knife positioning functions.

That difference in speed is intentional.

The rewinder must have enough capacity to process jumbo reels while accommodating roll changes and other interruptions without restricting the upstream paper machine.

This is another reminder that modern high-output paper production is a system problem.

The paper machine cannot be optimized in isolation from:

stock preparation,

automation,

rewinding,

material handling,

and maintenance.

Design speed is only the beginning

Voith describes PM47 as one of the world’s fastest-running multi-fourdrinier packaging paper machines.

That is a supplier claim tied specifically to this machine configuration and should be reported that way.

There are other modern packaging machines with comparable design speeds. For example, SCA’s Voith-supplied Obbola PM2 kraftliner machine also has a design speed of 1,400 m/min and capacity of roughly 725,000 tonnes per year, although it uses a different machine configuration.

So the strongest PM47 benchmark is not simply “fastest paper machine.”

It is the combination of:

wide machine + high capacity + multi-fourdrinier configuration + exceptionally rapid execution and ramp-up.

That is both more precise and more meaningful.

The real benchmark comes after startup

Ten days to maximum operating speed is an exceptional commissioning milestone.

But maximum speed is not the same as sustained commercial performance.

The more useful numbers over the next year will be:

operating efficiency,

saleable production,

grade-change performance,

specific energy use,

fibre yield,

downtime,

and quality consistency.

A machine can briefly reach 1,400 m/min.

The harder achievement is operating close to its economic optimum day after day.

That distinction matters when judging any supplier’s startup announcement.

Still, PM47 has already passed one difficult test unusually quickly.

It moved from construction to first reel in slightly more than 11 months and from startup to maximum operating speed in only 10 days.

For a machine designed to produce 700,000 tonnes of packaging paper every year, shortening those transition periods has direct commercial value.

The next generation of paper-machine competition therefore may not be defined by maximum speed alone.

It will increasingly be defined by how quickly mills can convert new capacity from installed steel into stable, saleable tonnes.

And on that measure, Sun Paper’s PM47 has set a demanding benchmark.
