Abstract

Provided are a degradable food packaging material and a preparation method thereof. The degradable food packaging material is prepared by the following raw materials by weight: 120-130 parts of grape vine powder, 20-23 parts of chaff powder, 14-16 parts of flour, 4-5 parts of calcium sulfate whisker, 2-3 parts of vegetable oil, 1 part to 2 parts of codonopsis pilosula, 2-3 parts of angelica sinensis, 1 part to 2 parts of red-tooted salvia root, 1 part to 2 parts of Rubiaceae Borreria stricta, 4-5 parts of gelatin, 1 part to 2 parts of zinc gluconate, 2-3 parts of mannitol, 8-9 parts of bonding assistant and a defined amount of water. The degradable food packaging material can be quickly degraded within 2-5 days, is especially suitable for manufacture of fast food boxes and is simple in manufacture process, abundant in raw material source and low in manufacture cost.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a degradable food packaging material and a preparation method thereof. Background technique [0002] Nowadays, the pollution of chemical materials is becoming more and more serious, which endangers the living environment of human beings. Therefore, the development of degradable materials meets the needs of ecological development. There is a huge market demand. The disposable lunch boxes used in the market are made of polypropylene foam, which pollutes the environment; it is very urgent to research and develop disposable and degradable foam materials. Materials, the preparation of degradable foam materials, is of great significance. Contents of the invention [0003] The purpose of the present invention is to provide a degradable food packaging material and a preparation method thereof. The material adopted is harmless to the environment, can be degraded, and is environmenta...
