Problems solved by technology

Food bags generally include plastic food bags and paper food bags. Plastic food bags are widely used because of their waterproof, high mechanical strength and light weight; but on the other hand, plastic food bags are easily deformed and damaged during the process of holding high-temperature food. And the additives in plastic food bags are easy to decompose and cause food pollution
[0003] Compared with these defects of plastic food bags and the enhancement of people's awareness of environmental protection, the use of paper food bags is gradually increasing, but paper food bags are easy to be damp and breed bacteria, which will affect the quality of food and endanger people's health

Abstract

The invention discloses a preparation method of an antibacterial food bag. The method includes the steps that firstly, raw materials and limewash are mixed and cooked to obtain pulp; secondly, the pulp is subjected to washing, bleaching, ramming, paper fishing and drying to prepare antibacterial paper; thirdly, the antibacterial paper is processed into the antibacterial food bag, wherein the raw materials include bark, chitin fiber, aloe, fructus forsythiae, folium isatidis and selfheal. The antibacterial food bag prepared through the method has high breaking resistance and antibacterial performance. The raw materials in the preparation method are easy to obtain. The antibacterial food bag can be produced on a large scale.

Description

technical field [0001] The invention relates to a food bag, in particular to an antibacterial food bag and a preparation method thereof. Background technique [0002] Food bags are indispensable in people's daily life and bring great convenience to people in food storage and transportation. Food bags generally include plastic food bags and paper food bags. Plastic food bags are widely used because of their waterproof, high mechanical strength and light weight; but on the other hand, plastic food bags are easily deformed and damaged during the process of holding high-temperature food. And the additives in plastic food bags are easy to decompose and cause food pollution. [0003] Compared with these defects of plastic food bags and the enhancement of people's awareness of environmental protection, the use of paper food bags is gradually increasing, but paper food bags are easy to be damp and breed bacteria, which will affect the quality of food and endanger people's health ....
