Abstract

The invention discloses a composite aluminum foil packing material of pearl wool. The composite aluminum foil packing material of pearl wool is prepared by curtain-coating and compounding a coating layer formed by pearl wool and an aluminum foil cast with a thickness of 15-40mum under temperatures 240 DEG C, 260 DEG C and 280 DEG C. An upper layer is the aluminum foil and a lower layer is the pearl wool. A coating material of the coating layer is a mixture of an adhesive and low-density polyethylene resin particles. The coating layer contains 30-45wt% of low-density polyethylene resin particles. The price of the low-density polyethylene resin particle is lower than that of the adhesive, so that the production cost of the composite aluminum foil packing material is reduced while the compound quality of the pearl wool and the aluminum foil is ensured.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a composite packaging material, in particular to a pearl cotton composite aluminum foil packaging material. Background technique [0002] EPE pearl cotton is a new type of environmentally friendly packaging material, which is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene. It overcomes the shortcomings of ordinary styrofoam such as fragility, deformation, and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. Good chemical resistance is an ideal substitute for traditional packaging materials, widely used in electronic appliances, instruments, computers, audio, medical equipment, industrial control chassis, hardware lighting, handicrafts, gl...
