35μm Translucent Blue Low Density Polyethylene Film (LDPE Film)
35 μm blue low density polyethylene film designed for packaging, agriculture, construction, medical applications, and more.
Key Applications
Food Packaging
Ideal for packaging fruits, vegetables, and meats. The translucent blue color helps protect food from UV damage while maintaining freshness.
Healthcare Industry
Widely used for medical bags, pouches, and essential items. The blue coloration indicates medical-purpose use and aids in content identification.
Industrial Packaging
Provides protection from UV rays, dust, and moisture for electronic and electrical components during packaging and storage.
Agriculture
Protects plants from harsh weather conditions while allowing optimal sunlight penetration for photosynthesis through its translucent blue properties.
Contamination Protection
Safeguards textiles, garments, and components from contamination, dirt, and dust during transportation and storage.

Performance Enhancement Methods
- Blending: Combining LDPE with LLDPE or HDPE to improve tensile strength, impact resistance, and stiffness
- Additives: Incorporating fillers, elastomers, and reinforcing agents to enhance strength, durability, and flexibility
- Coating: Applying acrylic, urethane, or silicone coatings to improve barrier properties, adhesion, and printing quality
- Orienting: Stretching film in machine or transverse directions to align polymer chains and improve strength and tear resistance
- Cross-linking: Modifying polymer chains to create a three-dimensional network for improved thermal stability and chemical resistance
- Process Control: Optimizing temperature, pressure, and extrusion speed during production to ensure consistent properties
