What gas does the pearl cotton factory use?

Butane gas is mainly low in packaging requirements and cheap in price.

Pearl cotton is a kind of non-crosslinked closed-cell polyethylene foam, also known as EPE pearl cotton, which is a new type of environmental protection packaging material. It consists of countless independent bubbles produced by physical foaming of low density polyethylene. Overcomes the shortcomings of ordinary styrofoam, such as brittleness, deformation and poor recovery. It has many advantages such as waterproof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on, and also has good chemical resistance. It is an ideal substitute for traditional packaging materials.
