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 composed of countless independent bubbles formed by physical foaming of low-density polyethylene. 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, as well as excellent chemical resistance. It is an ideal substitute for traditional packaging materials.

Widely used for packaging 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, spray painting, furniture, leather shoes, daily necessities, and high-end fragile gift packaging such as alcohol and resins, as well as hardware products, toys, fruits and vegetables, and shoe packaging. Enhanced with colorant antistatic agents and flame retardants, it showcases superior performance.
