Stretch Film Blog — Technical Insights from the Factory Floor
Practical Guidance on Pallet Wrapping, Film Selection & Cost Control.
Written by the Vistech engineering team, our articles cover the decisions that matter on real pallet lines: choosing gauges, comparing wrap methods, passing audits, protecting loads in automated and cold-chain warehouses, and cutting cost per pallet without cutting protection. Every recommendation is grounded in what we see every day on our own cast extrusion and slitting lines in Dongguan.

What We Write About
Six Topic Lanes, One Goal: Better Wrapped Pallets
Every article on this blog falls into one of six lanes. Browse by the problem you are trying to solve — or contact us directly and get the answer from an engineer instead of an article.
Hand Film & Ergonomics
Grip, tensión do pulso, dispenser choice, thickness selection and safe wrapping technique for manual pallet wrapping.
Machine Film Performance
Puncture resistance, forza de contención, pre-stretch settings and film behavior on rotary turntable and fully automatic wrappers.
Warehouse Automation & Cold Chain
Keeping loads stable in AS/RS high-bay racking, freezer warehouses and other demanding handling environments.
Standards & Testing
ASTM test methods, quality benchmarks and how to read a supplier data sheet with a critical eye.
Cost & ROI
Cost per pallet, downgauging economics and total cost of ownership versus alternative load-securing methods.
Materials & Manufacturing
Co-extrusion architecture, resin selection and what really happens on the cast line that changes film performance.

Reading Is Good. Testing Is Better.
Articles give you the framework — your load, your wrapper and your transit route decide the final spec. Send us your pallet weight, dimensions and wrapping equipment, and our engineers will recommend the right film with supporting test data.
