Abstract

The invention discloses a degradable breakfast cake packaging material based on orange peel residues. The material is prepared from components in parts by weight as follows: 30-60 parts of orange peelresidue particles, 30-60 parts of soybean hull, 3-8 parts of diphenylmethane diisocyanate, 12-26 parts of polylactic acid fiber, 8-15 parts of polyvinyl alcohol, 3-8 parts of algin, 1-3 parts of foodcoloring, 0.8-2.5 parts of zinc ricinoleate, 2-6 parts of glycyrrhetinic acid, 1-3 parts of zinc gluconate, 5-13 parts of carrageenan, 4-10 parts of konjac glucomannan, 1.5-6 parts of a plant fiber modifier, 1-3 parts of procyanidine and 9-16 parts of mannitol. The degradable breakfast cake packaging material cannot cause environmental pollution due to good degradability.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a degradable breakfast cake packaging material based on citrus peel. Background technique [0002] In recent years, environmental pollution caused by waste plastics has attracted more and more attention. Disposable tableware, disposable plastic products, agricultural nutrition bowls, seedling throwing trays, etc. are difficult to recycle, and their treatment methods are mostly incineration and landfill. Incineration of plastic products will produce a large amount of harmful gases, which will pollute the environment; while burying plastic products will also pollute the environment because the polymers in them cannot be decomposed by microorganisms in a short time. The presence of discarded plastic products in the soil will hinder the development of crop roots and the absorption of water and nutrients, and will reduce the air permeability of the soil, resulting in reduced crop y...
