Abstract

The invention relates to the technical field of packaging materials and discloses a degradable PLA biological composite packaging material and a preparation method thereof. The degradable PLA biological composite packaging material is prepared from the following raw materials in parts by mass: 15 to 30 parts of starch, 15 to 25 parts of clay, 5 to 10 parts of float glue, 10 to 15 parts of vegetable fibers, 5 to 7 parts of an adhesion promoter, 3 to 7 parts of polylactic acid, 3 to 5 parts of polypropylene, 10 to 18 parts of carrageenan, 3 to 6 parts of sodium xylene sulfonate, 12 to 15 parts of gelatin, 5 to 7 parts of a plasticizer, 3 to 7 parts of an antioxidant, 2 to 4 parts of a coupling agent and proper amount of a foaming agent. According to the degradable PLA biological composite packaging material and the preparation method thereof, the problem that existing packaging materials have serious pollution to the environment can be solved.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a degradable PLA biocomposite packaging material and a preparation method thereof. Background technique [0002] Plastic, with its advantages of light weight, high strength, corrosion resistance, and convenient transportation, has been widely used in recent years. In my country, in 2016 alone, the total output of plastic products exceeded 77 million tons, a year-on-year increase of 2.7%. The usual way of disposal is large-scale landfill or open incineration, which will generate at least 150 million tons of plastic packaging waste every year. The recovery rate is only 2%. With the rapid development of modern industry, people's awareness of environmental protection is quietly awakening. In 2008, the "Plastic Restriction Order" was issued, but it was only a temporary solution, not the root cause. The development and research of degradable packaging materials is the only...
