Problems solved by technology

[0005] Both the single pearl cotton and the bubble film limit their respective application ranges, and the two can be used in combination, but in the process of casting the bubble film and the pearl cotton Coating materials such as adhesives need to be used. Due to the high price of adhesives, the cost of pearl cotton composite air bubble film packaging materials is relatively high

Embodiment 1

[0015] 70wt% of adhesive and 30wt% of low-density polyethylene resin particles are mixed as the coating layer, and the pearl cotton and air bubble film are cast and compounded at 240°C, and the diameter of the bubble body of the air bubble film is 3 mm.

Embodiment 2

[0017] 65wt% of adhesive and 35wt% of low-density polyethylene resin particles are mixed as the coating layer, and the pearl cotton and air bubble film are cast and compounded at 260°C, and the diameter of the bubble body of the air bubble film is 30 mm.

Embodiment 3

[0019] 60wt% of adhesive and 40wt% of low-density polyethylene resin particles are mixed as the coating layer, and the pearl cotton and air bubble film are cast and compounded at 280°C, and the diameter of the bubble body of the air bubble film is 12 mm.

Abstract

The invention discloses a composite EPE-air bubble film packaging material. The material is prepared by compounding EPE and an air bubble film through tape casting of a coating layer which is obtained by mixing an adhesive and a low density polyethylene resin particle, wherein an upper layer is the EPE, a lower layer is the air bubble film, the usage amount of the low density polyethylene resin particle accounts for 30 to 40% of the weight of a coating material, and the diameter of an air bubble body of the air bubble film is 3 to 30 mm. Since the low density polyethylene resin particle is cheaper than the adhesive, the composite EPE-air bubble film packaging material provided by the invention has reduced production cost while the compounding quality of the EPE and the air bubble film 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 bubble film 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, glass...
