Cost equation
Total cost/kg = net material + scrap effect + energy + labor + maintenance + allocated production overhead, all on the same time basis.
Material and scrap
Material is often dominant. Measure startup, changeover, off-spec and trim scrap, together with the amount actually recovered.
Energy and throughput
Measure kWh/kg, not motor kW alone, because throughput and idle time determine unit energy.
Use ROI with discipline
Build a multi-month baseline, state assumptions and test sensitivity to resin price, utilization, scrap and output before accepting payback.
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.
