Abstract

The invention provides a degradable bubble protective film and a processing method thereof. The degradable bubble protective film of the invention solves the technical problems that conventional bubble protective films cannot be degraded, easily cause white pollution, has poor environmental protection performance and the like. The degradable bubble protective film of the invention is composed of the following components by weight: 60-80 parts of low-density polyethylene, 3-5 parts of an antioxidant, 1.5-2.5 parts of a plasticizer and 2.4-4.6 parts of a biodegradable additive. The degradable bubble protective film of the invention has the advantages of good environmental protection performance.

Description

technical field [0001] The invention relates to a degradable air bubble protective film and a processing method thereof. Background technique [0002] The bubble film is made of high-pressure polyethylene as the main raw material, and then added whitening agent, opening agent and other auxiliary materials, and extruded at high temperature to form bubbles. It is a new type of plastic with light texture, good transparency, non-toxic and tasteless. Packaging materials can protect products from moisture, cushioning, and heat preservation. [0003] After searching, for example, Chinese patent literature discloses a bubble protection film [application number: 201120241400.3; publication number: CN 202163739U]. This kind of packaging buffer pad includes a plastic film. A buffer film is arranged on one or both sides of the plastic film. Bubbles for buffering are arranged on the buffer film. It is characterized in that the top of the bubble is hemispherical and the lower part is cyl...
