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
The present invention relates to a kind of plastic packaging bag, particularly relate to the preparation method of a kind of food plastic packaging bag.
Background technology
At present, existing food plastic packaging bag is essentially all what polymeric materials such as using polyethylene was made, such plastic packaging bag is providing easily simultaneously, owing to they cannot be degraded, use in a large number and recycle not in place, causing substantial amounts of non-compliant food plastic packaging bag.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of food plastic packaging bag, use advantages of nontoxic raw materials harmless, and with the addition of degradation of promoter, thus the non-compliant problem of food plastic packaging bag in the presence of solving prior art.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of preparation method of food plastic packaging bag, this packaging bag is made up of following component in parts by weight: linear low density polyethylene resin 100 parts, polylactic acid 8-15 part, heavy calcium carbonate 5-10 part, polyvinyl alcohol 5-8 part, methyl methacrylate 10-15 part, degradation of promoter 2-5 part, its preparation method is: use high-speed mixer to be stirred by above-mentioned material, mixing time 30-40 minute, rotating speed 220-280 rev/min；Using blow moulding machine that the material after mix homogeneously carries out blow molding is food plastic packaging bag.
Owing to using technique scheme, there is advantages that
The present invention uses linear low density polyethylene, heavy calcium carbonate and polylactic acid as raw material, uses advantages of nontoxic raw materials harmless, and with the addition of degradation of promoter, thus the non-compliant problem of food plastic packaging bag in the presence of solving prior art.
