50μm Blue Low Density Polyethylene Film
50 μm blue low density polyethylene film designed for insulation, roofing, packaging, agriculture, construction, medical applications, and more.
Product Overview
Low-density polyethylene (LDPE) film is a flexible, durable, and moisture-resistant plastic film suitable for diverse industrial applications.
Primary Applications
- Packaging: Flexible packaging applications including bags, shrink wrap, and stretch film
- Agriculture: Greenhouse covers, mulch film, and silage bags
- Construction: Barrier protection material for construction sites, insulation, and roofing
- Medical: Disposable gloves and medical packaging
LDPE vs HDPE Comparison
LDPE film has lower density than HDPE film, making it softer, more flexible, and more transparent. HDPE film is more rigid, less flexible, and more opaque with higher tensile strength and puncture resistance. LDPE offers superior conformability and heat sealing capabilities.
