Abstract

The invention discloses a preparation method of natural degradable antimicrobial wrapping paper. The method basically comprises steps of raw material preparation, defibering, beating, pulp preparationand fine grinding, papermaking, squeezing and drying. The formed natural degradable antimicrobial wrapping paper has the advantages of oxygen isolation, good antibacterial property and degradation. The preparation method adopts a nanometer embedding technology, adopts chitosan Arabic gum and essential oil to prepare a nanometer compound to be added into pulp, improves the oxygen resistance and the antibacterial property of the paper, is simple, and convenient to operate, further provides a novel approach for processing of by-products through peel agricultural and forestry products, sufficiently utilizes resources, and relieves environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of wrapping paper, and in particular relates to a preparation method of naturally degradable antibacterial wrapping paper. Background technique [0002] Since the 21st century, people's living standards have been greatly improved, and the demand for packaging of various products is also increasing. At present, food packaging materials in the world mainly rely on plastic, paper, and metal. Big problem: The safety of materials has been questioned, excessive consumption of resources and energy, endangering the environment and not meeting the requirements of low-carbon environmental protection. Paper packaging materials are currently widely used food packaging materials due to their good physical properties, strong mechanical operability, environmental protection, recycling, and cost savings.
