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

Widely used in packaging for a variety of products including car seat cushions, pillow, electronic appliances, instruments, computers, audio equipment, industrial computer cases, hardware lighting, crafts, glass, ceramics, household appliances, spraying, furniture, leather shoes, and high-end fragile gift items such as alcohol and resins, as well as for daily necessities and express shipping packaging. Enhanced with colored antistatic agents and flame retardants, it boasts superior performance.
