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 absorb moisture and damp, which will lead to mildew and odor.

Abstract

The invention discloses an anti-odor food bag and a preparation method thereof. The preparation method comprises the steps that 1, raw materials are mixed with whitewash, cooking is conducted, and paper pulp is obtained; 2, the paper pulp is subjected to material washing, bleaching, ramming, paper fishing and drying to obtain anti-odor paper; 3, the anti-odor paper is processed into the anti-odor food bag; the raw materials comprise bark, glass fibers, aloes, cactuses, chlorophytum comosum, dianthus chinensis L., chrysanthemum flowers and canna indica L.. The anti-odor food bag prepared through the preparation method can effectively inhibit odor, caused by mildew, of contained food. Meanwhile, the raw materials in the preparation method are easy to obtain, and industrial production of the anti-odor food bag can be achieved.

Description

technical field [0001] The invention relates to a food bag, in particular to an anti-odor 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 absorb moisture and damp, and then mildew and produce peculiar smell.
