70μm White CPE Film
High-quality 70μm white CPE film featuring uniform thickness, pure white color, smooth surface, non-toxic properties, and odorless characteristics. Ideal for flexible packaging, lamination, and industrial & daily chemical packaging applications.
Manufacturing Process
Our 70μm white CPE (Cast Polyethylene) film is manufactured through precision cast extrusion. High-purity PE resins, food-grade white color masterbatch, and eco-friendly additives are blended in high-efficiency mixers. The compound undergoes single-screw extrusion with controlled temperature conditions (165-185℃), followed by precision flat die extrusion, instant cooling via chrome-plated chill rolls, and strict quality inspection before final packaging.
Product Features
  • Stable physical properties with thickness controlled within 70μm ±2μm
  • Even, pure white appearance without color deviation, bubbles, or surface defects
  • Smooth, flat surface with excellent flexibility and superior toughness
  • Resists tearing and puncturing with non-toxic, tasteless properties
  • Compliant with international food contact safety standards
  • Excellent heat sealability and compatibility for secondary processing
Competitive Advantages
  • Advanced cast extrusion technology ensures ultra-uniform thickness and product consistency
  • Low heat seal temperature with strong seal strength reduces packaging costs
  • Lightweight yet durable with excellent moisture barrier and corrosion resistance
  • Cost-effective solution customizable in width, roll length, and surface finish
  • Superior dimensional accuracy compared to blown film alternatives
Application Fields
  • Flexible packaging for food (snack bags, frozen food wrappers, candy packaging)
  • Daily chemical packaging (toilet paper rolls, detergent bags)
  • Industrial packaging (small components, electronic parts)
  • Lamination base film for composite packaging
  • Sanitary product packaging (sanitary napkins, diapers)
  • Agricultural packaging (seed bags, fertilizer packaging)
