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 countless independent bubbles produced by physical foaming of low-density polyethylene. It overcomes the drawbacks 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 moldability, 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 for packaging a variety of products including car seat cushions, pillows, electronic appliances, instruments, computers, audio equipment, industrial computer cases, hardware lighting, crafts, glass, ceramics, household appliances, coatings, furniture, leather shoes, and high-end fragile gift items such as alcohol and resins, as well as daily necessities and express packaging. Enhanced with colorant antistatic agents and flame retardants, it showcases superior performance.
