Abstract

The invention discloses an anti-mould food bag and a preparation method thereof. The preparation method comprises the following steps: (1) mixing raw materials and limewater, and digesting to prepare a pulp; (2) performing diffusion, bleaching in the sun, ramming, fishing, bleeding white and steaming on the pulp to produce anti-mould paper; (3) processing anti-mould paper into an anti-mould food bag. The raw materials comprise bamboo, bark, hemp, herb of waterplantain ottelia, natural silk, glass fibers, cyrtomium rhizome, radix euphorbia pekinensis, akebia stem, herba agrimoniae, radix rubiae, ash bark, radix curcumae longae, flos chrysanthemi, bunge corydalis herb, flos caryophylli, flos lonicerae and rhizoma polygonati. The anti-mould food bag prepared by the method has excellent mechanical strength and anti-mould capability, and the raw materials are easy to obtain, so that industrial batch production of the anti-mould food bag can be realized.

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, as the name suggests, are bags for food, a small bag, which brings great convenience to human life. Food bags can be divided into plastic food bags and paper food bags according to the material classification. Plastic food bags are widely used because of their waterproof, high mechanical strength and light weight, but plastic food bags are easy to cause environmental pollution and their usage is gradually increasing. At the same time, the plastic food bags are easily deformed in the process of containing high-temperature food, and the additives in the food bags are easily decomposed and cause contamination to the food. In view of the defects of plastic food bags, the use of paper food bags is gradually increasing. [0003] Although paper food bags have excellent degradability and are stable under high ...
