Polyethylene foam is a non-crosslinked closed-cell structure, also known as EPE pearl cotton, and is a new type of environmentally friendly packaging material. It is composed of numerous independent bubbles formed by physical foaming of low-density polyethylene resin. It overcomes the shortcomings of common foam materials, such as fragility, deformation, and poor resilience. It boasts many advantages, including waterproof and moisture-proof, shockproof, soundproof, thermal insulation, excellent plasticity, strong toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance. It is an ideal substitute for traditional packaging materials.

Widely used for packaging a variety of products including car seat cushions, pillows, electronic appliances, instruments, computers, audio equipment, industrial computer enclosures, hardware lighting, crafts, glass, ceramics, home appliances, coatings, furniture, leather shoes, and high-end fragile gift items such as alcohol and resins, as well as hardware products, toys, fruits and vegetables, and daily necessities. Additionally, it is used for express package. Enhanced with colored antistatic agents and flame retardants, it showcases superior performance.
