Abstract

The invention provides a bacteriostatic and degradable food packaging film and a preparation method thereof. The bacteriostatic and degradable food packaging film is prepared from the following raw materials in parts by weight: 50-80 parts of crop straw, 10-20 parts of succinic glycoside, 10-20 parts of polybutylene succinate, 12-22 parts of polylactic acid, 8-16 parts of polyvinyl alcohol, 6-12 parts of sepiolite, 5-10 parts of zinc oxide, 8-15 parts of silicon dioxide, 4-8 parts of gamma-aminopropyltriethoxysilane, 3-8 parts of a dispersing agent, 8-16 parts of tea polyphenol, 10-16 parts ofchitosan, 9-15 parts of sodium benzoate, 15-30 parts of N methylmorpholine-N-oxide NMMO / water, 4-9 parts of dodecyl trimethyl ammonium chloride, 2-7 parts of 1-ethyl-3-methylimidazolium tetrafluoroborate, 8-14 parts of isopropanol and 10-20 parts of water. The bacteriostatic and degradable food packaging film has excellent antibacterial performance, mechanical properties, moisture and gas permeability and degradability and has a broad application prospect in the field of food packaging.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to an antibacterial and degradable food packaging film and a preparation method thereof. Background technique [0002] Most of the existing food packaging films are plastic packaging films. Although plastic packaging films have good barrier properties and play a good packaging effect, their air permeability is poor, which is easy to breed microorganisms such as bacteria. At the same time, the degradability of plastic packaging film is poor, and the extensive use of plastic packaging film makes white pollution more and more serious, which cannot meet people's demand for green environmental protection. Therefore, the degradable food packaging film with good antibacterial effect has become a research hotspot. [0003] The packaging film with cellulose as the base material has become one of the directions of people's research. Cellulose has abundant material sou...
