SGS Opaque Red Low Density Polyethylene Film For Packaging
120 μm red low density polyethylene film designed for packaging, agriculture, construction, medical, and various industrial applications.
About Low-Density Polyethylene (LDPE) Film
Low-density polyethylene film is a flexible, durable, and moisture-resistant plastic material widely used across multiple industries.
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 offers higher density, resulting in greater rigidity, opacity, tensile strength, and puncture resistance. LDPE provides superior conformability and heat sealing capabilities.
