Problems solved by technology

The current packaging industry says that the number and types of packaging substrate films required are large, and it is difficult to adapt to special packaging requirements for films produced with a single raw material
However, the existing packaging plastic film still has the disadvantages of poor stretchability and water resistance. Therefore, the present invention provides a new type of packaging plastic film, which can adapt to special packaging requirements

Abstract

The invention discloses a package plastic film which comprises the following raw materials in parts by weight: 20-35 parts of PC (polycarbonate), 25-40 parts of APET (amorphous polyester), 18-26 parts of PLA (polylactic acid), 4-6 parts of 2-hydroxypropyl-beta-cyclodextrin, 5-11 parts of ASA (acetyl salicylic acid) high glue powder, 7-18 parts of polyamide wax powder, 2-8 parts of 4-dimethylamino isoamyl benzoate, 5-18 parts of trehalose, 5-11 parts of diacetyl tartaric acid ester of mono(di) glycerides, 11-18 parts of tartrate, 11-18 parts of bisphenol A cyanate ester, 4-10 parts of polybutylene terephthalate, 2-5 parts of 3,5-diaminobenzoic acid, 5-11 parts of petroleum coke and 0.1-0.5 part of lithium amide. The package plastic film has good tensile capacity and water resistance since the raw materials are compounded to exert a synergistic effect; the production cost is low; a production technology is simple; the industrial production is facilitated; and the package plastic film can be manufactured into various package bags, and has a higher practical value and a high market popularization value.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a packaging plastic film. Background technique [0002] my country is a big packaging manufacturing and consuming country in the world. The proportion of plastic packaging in the total output value of the packaging industry has exceeded 30%. It has become a new force in the packaging industry and plays an irreplaceable role in various fields of food, beverages, daily necessities, and industrial and agricultural production. In recent years, the packaging products and packaging materials in the plastic packaging industry have grown steadily, and new packaging materials, new processes, new technologies, and new products are constantly emerging. The current packaging industry says that the number and variety of packaging substrate films required are large, and it is difficult to adapt to special packaging requirements for films produced from a single raw material. However, th...
