The production process
Resin is melted and mixed in the extruder, formed into a tube through the die, inflated as a bubble, cooled and stabilized, then collapsed and wound. Each stage affects gauge consistency, roll quality and operating continuity.
Single Layer, ABA, ABC and multilayer
Single Layer suits straightforward structures. ABA separates surface layers from a core. ABC permits three differentiated layers. A 3–5 layer line supports more complex structures when formulation flexibility or functional film properties justify it.
Numbers required before selection
Define film width, thickness range, target kg/h, operating hours, resin family and roll format. If a value is uncertain, separate current, target and acceptable-range assumptions.
A factory decision framework
Identify whether the constraint is extrusion, cooling, winding or converting, then compare cost per kilogram at realistic utilization. The largest machine is not automatically the best investment when downstream equipment or demand cannot use its capacity.
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.
