Abstract

The invention discloses a preparation method of a plastic package bag for food. The package bag is prepared from the following ingredients in parts by weight: 100 parts of linear low density polyethylene, 8 to 15 parts of polylactic acid, 5 to 10 parts of ground limestone powder, 5 to 8 parts of polyvinyl alcohol, 10 to 15 parts of methyl methacrylate and 2 to 5 parts of degradation promoters. The preparation method comprises the following steps that a high-speed mixing machine is used for sufficiently and uniformly stirring the materials, wherein the stirring time is 30 to 40 minutes, and the rotating speed is 220 to 280 r / minute; a blow moulding machine is used for performing blow moulding forming on the uniformly mixed materials to form the plastic package bag for food.

Description

technical field [0001] The invention relates to a plastic packaging bag, in particular to a method for preparing a plastic packaging bag for food. Background technique [0002] At present, the existing plastic packaging bags for food are basically made of polymer materials such as polyethylene. Such plastic packaging bags provide convenience, but because they cannot be degraded, they are used in large quantities and are not properly recycled, resulting in A large number of plastic packaging bags for food that do not meet the standards. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing plastic packaging bags for food, using non-toxic and harmless raw materials, and adding a degradation accelerator, so as to solve the problem that the plastic packaging bags for food in the prior art do not meet the standards . [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts fo...
