[0012] A PE film composite antistatic EPE comprises a PE film layer 1 and an antistatic EPE layer 2 compounded on the PE film layer, and the PE film and the antistatic EPE are bonded by hot melt. Antistatic EPE is made by adding antistatic agent to the raw material of EPE according to the conventional process. By adding antistatic agent, the surface of the product absorbs more moisture and forms a single molecular layer antistatic foam film, thereby accelerating the leakage of electrostatic charge. The surface resistance is about 10 6 -10 11 Ω, charge generation: (V) 2 24h.

The invention relates to PE film compounded antistatic EPE, which comprises a PE film layer and an antistatic EPE layer which are combined through hot melt; and the antistatic EPE is prepared by adding an antistatic material into an EPE raw material. The PE film compounded antistatic EPE has the characteristics of soft texture, elasticity, high tensile strength, waterproofing and moisture proofing, shock and pressure resistance, medium thickness and the like, and can prevent static and has buffering and shockproof functions when used for packaging electrical appliances, hardware, electronic components and modules such as boards, cards and the like.
Description
technical field [0001] The invention relates to a PE film composite antistatic EPE, which belongs to the field of packaging materials. Background technique [0002] PE film, that is, polyethylene film, is widely used in various fields. It has the characteristics of water and moisture resistance, softness and good stretchability, but it is easy to be damaged by external force and has no cushioning performance. [0003] EPE (Expandable polyethylene), also known as pearl cotton, is a new type of environmentally friendly foaming material with high-strength cushioning and shock resistance. It is produced by physical foaming of low-density polyethylene fat. Independent bubble formation. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, strong impact resistance, etc., and also has good chemical resistance. It is an ideal substitute for traditional packaging materials. Widely used in electronic appliances, instrum...
