40μm Cast Polyethylene Film

No-Residue Cast PE Film

Uniform Thickness High Density Polyethylene Film

Descrizione di prodotto

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.
