[0013] The invention provides a preparation method of a bactericidal food bag, comprising:

[0014] 1) mixing raw materials with lime water and cooking to make pulp;

[0015] 2) Washing the pulp, blanching, beating, fishing for paper, squeezing and baking paper to make sterilizing paper;

[0016] 3) Process the sterilizing paper into a sterilizing food bag;

[0017] Among them, the raw materials include bamboo, bark, hemp, asparagus, silk, glass fiber, perilla leaf, galangal, arborvitae leaf, pomegranate peel, loquat leaf, large thistle, red peony, capillary, dogwood, cassia, Curcuma and Shiwei.

[0018] In the present invention, the specific type of bamboo can be selected in a wide range, but in order to have more excellent mechanical properties and bactericidal ability in order to make the self-suicidal food bag, preferably, the bamboo is selected from one of Moso bamboo, bitter bamboo and Ci bamboo. one or more species.

[0019] In the present invention, the specific ty...

Embodiment 1

[0029] 1) At 150°C, mix the raw material with lime water (calcium hydroxide content is 0.17% by weight) and cook for 5 days to obtain pulp; wherein, the mass ratio of raw material to lime water is 1:4, and the raw material contains Moso bamboo, green sandalwood bark, hemp, asparagus, silk, glass fiber (1mm in length and 0.5mm in diameter), perilla leaf, galangal, arborvitae leaf, pomegranate peel, loquat leaf, thistle, red peony root, fungi Chen, dogwood, cassia, curcuma and stone reed (the weight ratio of each substance is 100:30:25:7:4:1.5:1:3.5:6:4:3:1.5:1.5:2:4:2:3 :2).

[0030] 2) washing the pulp until no spoils are washed out to obtain the washed pulp;

[0031] 3) Sun-whitening the above-mentioned washed pulp for two months at 25° C. to obtain sun-whitened pulp;

Abstract

The invention discloses a self-sterilization food bag and a preparation method thereof. The method comprises following steps: 1) mixing raw materials and whitewash, and boiling the mixed materials so as to obtain paper pulp; 2) washing, bleaching and flapping the paper pulp, and finishing, drying and baking the paper so as to obtain the sterilization paper; and 3) processing the sterilization paper so as to obtain the self-sterilization food bag. The raw materials comprise bamboo, bark, linen, Chinese alpine rush, silk, glass fibers, perilla leaves, galagal rhizome, biota orientalis, pomegranate rind, loquat leaves, cirsium japonicum, radix paeoniae rubra, oriental wormwood, cornus officinalis, cassia seeds, curcuma zedoary and pyrrosia leaves. The self-sterilization food bag prepared through the preparation method has excellent mechanical strength and sterilization capability, and the self-sterilization food bag can be industrially produced in batch as the raw materials in the preparation method can be easily obtained.

Description

technical field [0001] The invention relates to a food bag, in particular to a bactericidal food bag and a preparation method thereof. Background technique [0002] Food bags, as the name suggests, are bags for food, a small bag that brings great convenience to human life. According to the material classification, food bags can be divided into plastic food bags and paper food bags. Plastic food bags are widely used due to their waterproof, high mechanical strength and light weight. However, plastic food bags are easy to cause environmental pollution and their usage is gradually increasing. At the same time, plastic food bags are easy to deform during the process of containing high-temperature food, and the additives in the food bag are easy to decompose and cause food pollution. In response to the defects of plastic food bags, the number of paper food bags is gradually increasing. [0003] Although paper food bags have excellent degradability and are stable under high temp...
