Lightweight: The foaming structure gives the film an extremely low density, making it lightweight. This property not only reduces the overall weight of the packaged products but also helps in reducing transportation costs. Excellent Cushioning: It offers outstanding cushioning performance. The numerous small bubbles within the film can effectively absorb and disperse impact energy, protecting the packaged items from damage during handling, storage, and transportation. This makes it ideal for packaging fragile and delicate products such as electronics, glassware, and ceramics. Thermal Insulation: PE (PO) foam film has good thermal insulation capabilities. It can slow down the transfer of heat, which is beneficial for applications where temperature control is required. For example, it can be used in the packaging of temperature - sensitive products or in construction for insulation purposes. Chemical Resistance: The film is resistant to many chemicals, including acids, alkalis, and some organic solvents. This chemical resistance ensures the stability of the film when in contact with various substances, protecting the packaged items from chemical corrosion. Waterproof and Moisture - Proof: With its closed - cell foaming structure, the film provides excellent waterproof and moisture - proof properties. It can prevent water and moisture from penetrating, keeping the packaged items dry and in good condition, especially for products that are sensitive to moisture.
