Welcome to PolyFilm Lab — a channel about polyethylene film production and blown film extrusion.

Here you will see real manufacturing processes, extrusion equipment, polyethylene raw materials, film winding, quality control, troubleshooting, and practical production techniques.

We explore LDPE, LLDPE, MDPE and HDPE materials, shrink film production, film properties, extrusion technology, common production defects, and ways to improve film quality.

The goal of PolyFilm Lab is to share practical knowledge from real polyethylene film production — from polymer pellets to finished rolls.

New videos about polyethylene, blown film extrusion and plastic film manufacturing.
