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 prone to moisture and mold, which in turn affects the quality of food.

Abstract

The invention discloses a preparation method of an anti-mildew food bag. The preparation method includes: step 1, mixing raw materials and lime water, and boiling to obtain paper pulp; step 2, subjecting the paper pulp to washing, sun-whitening, beating, paper fishing and drying to obtain anti-mildew paper; step 3, processing the anti-mildew paper into the anti-mildew food bag, wherein the raw materials include tree bark, glass fiber, hairy-vein agrimonia herb, aloe, tea leaf, Herba kalimeridis and Lonicera japonica. The anti-mildew food bag made by the method has excellent mechanical strength and anti-mildew performance.

Description

technical field [0001] The invention relates to a food bag, in particular to an anti-mold 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.
