What Is the Production Capacity of a Stretch Film Machine?

A lot of buyers ask the same question: how much can this thing actually produce per hour? It's a fair question, but the answer isn't a single number. It depends on which machine you're looking at.

Let me walk you through what we actually ship from our factory.

Take our standard automatic line, like the WT-65/90/65. This one gives you about 220 kg per hour. Film width goes up to 1850mm, thickness from 8 to 50 microns. It's a solid choice for a small to medium factory running one or two shifts. Nothing overly complicated, but it runs day after day without drama.

If you need more output, look at our three-shaft automatic line, the WT-80/120/80. This one does 420 kg per hour at 250 meters per minute. The main screw diameter is 80mm with a 30:1 L/D ratio. We use JC-Times dies on this model — widely considered the best in China — so the film comes out uniform and stable. The cooling roller is double-spiral, 980mm in diameter. Why does that matter? Because at high speed, cooling is usually the bottleneck. If the roller can't pull heat away fast enough, you have to slow down. This roller handles it.

Now for the heavy lifting. If you're running 24/7 for export orders, you want our back rest automatic line. Same screw configuration — 80/120/80 — but tuned differently. Output ranges from 400 to 550 kg per hour, depending on film thickness and line speed. Max design speed hits 280 meters per minute. Power consumption runs about 0.4 kWh per kg, which is actually very efficient for this class of machine.

Let me put that in real numbers. At 500 kg per hour, running 22 hours a day, you're looking at about 11 tons per day. That's over 300 tons a month. For a factory filling containers for overseas customers, that's the kind of number that matters.

A few technical points that actually make a difference in daily operation. The back rest line uses imported high-speed bearings — rated lifespan over 10 years even at 280 m/min. The PLC is Siemens with 5G communication, so we can run remote diagnostics from our end. No need to fly someone in for every small issue. And the whole machine can be run by one person. Automatic paper core loading, automatic roll unloading, automatic spare shaft loading. That's not just convenience — that's labor cost saved every single shift.

We've sold over 60 of these jumbo roll machines to Turkey and Middle East countries. They keep coming back because the numbers on the spec sheet match what happens on their factory floor.

So here's the practical takeaway. If your target is under 250 kg per hour, the standard line is fine. If you need 350 to 420 kg per hour, go with the three-shaft automatic. And if you need to push 500 kg per hour or more, day and night, then the back rest line is the right tool.

Tell me your monthly target and what thickness you mostly run. That's all I need to recommend the right model.
