Abstract

The invention discloses a food packaging material and a preparing method thereof. The food packaging material comprises raw materials, by weight, 12-25 parts of ethylene-ethyl acrylate copolymer, 10-20 parts of polylactic acid, 12-22 parts of low density polyethylene, 1-3 parts of tert-butylhydroquinone, 4-11 parts of octyl-succinyl starch ester, 4-9 parts of sodium carboxymethyl cellulose, 4-9 parts of wheat starch, 0.5-1.3 parts of potassium sorbate, 4-8 parts of glycerin, 1.5-5 parts of chitosan, 5-10 parts of polysorbate, 0.5-1.5 parts of cinnamic acid, 3-8 parts of triethylene tetramine, 2.5-6 parts of methacryloxy propyl trimethoxyl silane, 4-9 parts of cellulose acetate butyrate and 0.6-1.8 parts of zinc ricinoleate. The food packaging material has the good mechanical property and degradation property and low environmental pollution.

Description

technical field [0001] The invention belongs to the field of packaging material manufacturing, in particular to a food packaging material and a preparation method thereof. Background technique [0002] With the development of social economy, what people pursue is no longer just to eat enough, but to eat well. At the same time, due to the rapid development of the transportation industry, the development of the food industry is also rapid, and the circulation and scale become wider and wider. In the process of food circulation and transportation, how to maintain the quality of food is a key. The existing food packaging materials have poor mechanical properties, and poor elasticity and toughness, which makes food packaging materials prone to damage and packaged food. It is corroded by bacteria; in addition, the existing packaging materials also have disadvantages such as poor degradation performance and large environmental pollution. Contents of the invention [0003] The ob...
