High Light 40μm Cast Polyethylene FilmNo-Residue Cast PE FilmUniform Thickness High Density Polyethylene Film
Cast Polyethylene Film - 40μm Protective Film for Electronics
Our 40μm cast polyethylene film is engineered for electronics protection with no-residue performance, uniform thickness, excellent flexibility, and stable processing characteristics. This soft, smooth film delivers reliable protection for sensitive electronic components.
Manufacturing Process
The production of cast polyethylene film involves precise raw material proportioning, melt extrusion, casting, cooling and setting, traction and stretching, edge material recycling, corona treatment, and final winding and slitting to produce flat, uniform film products.
Key Product Features
  • Uniform thickness distribution for consistent performance
  • High transparency and smooth surface finish
  • Excellent heat sealability with wide temperature range
  • Low internal stress for superior dimensional stability
  • Good toughness and flexibility
  • No-residue formulation for electronics protection
  • Stable processing characteristics
Cast PE Film vs Blown PE Film Comparison
Comparison Dimension Cast Polyethylene Film Blown PE Film
Thickness Uniformity Advantage: Small thickness deviation (±5%) due to precise T-die extrusion control Disadvantage: Larger thickness deviation (±8-10%) affected by blowing process
Transparency & Flatness Advantage: High transparency (90%+) and smooth surface without wrinkles Disadvantage: Lower transparency with uneven, wrinkled surface
Internal Stress Advantage: Low internal stress with good dimensional stability Disadvantage: High internal stress causing warping and deformation
Heat-Sealing Performance Advantage: Excellent heat-sealing with stable strength and wide temperature range Disadvantage: Poor heat-sealing with unstable strength and narrow range
Post-Processing Adaptability Advantage: Good adaptability for corona treatment, printing and lamination Disadvantage: Relatively poor post-processing adaptability
Production Efficiency Advantage: High line speed (50-150m/min) with online edge material recycling Disadvantage: Lower line speed (20-50m/min) with higher material loss
Note: The above advantages and disadvantages are based on conventional production processes. With continuous technology upgrades, the performance gap between both film types is gradually narrowing in some aspects.
