TECHNICAL GUIDE

How to Select a Blown Film Machine by kg/h

Required kg/h should be derived from demand, schedule and realistic utilization. Selecting only by a catalog maximum can oversize the investment or move the bottleneck downstream.

Calculate demand

Divide monthly volume by genuinely available operating hours, then account separately for downtime, changeovers, scrap and growth.

Nominal vs usable output

Catalog capacity is a reference range. Planning output must match resin, thickness, width and acceptable roll quality.

Check the complete line

Printing, bag making, QC, material handling and labor must absorb the output. Otherwise added extrusion capacity becomes work in process.

Run scenarios

Compare conservative, expected and high-demand cases with cost/kg and payback to expose utilization risk.

Frequently Asked Questions

Does this guide guarantee machine performance?

No. Final performance depends on resin, formulation, film dimensions, operating conditions and the confirmed machine configuration.

What information should a factory prepare?

Prepare the product sample, material and formulation, width, gauge, target output, downstream process, current constraint and project timeline.

TECHNICAL GUIDE

What Is a Blown Film Machine and How Should a Factory Choose One?

A blown film line turns resin pellets into tubular film through melting, die extrusion, bubble inflation, cooling, collapsing and winding. Correct selection starts with the product and production numbers—not a model name.

Single Layer vs ABA: Which Configuration Fits?

The useful question is not whether ABA is better than Single Layer, but how much layer and formulation flexibility the application requires.

TECHNICAL GUIDE

ABA vs ABC: How Should a Factory Choose?

ABA and ABC are both three-layer structures, but they differ in extruder arrangement and formulation freedom. Selection should follow the product requirement, not an assumption that more complexity is always better.
