Abstract

The invention discloses a luffa fiber antibacterial wrapping paper and a preparation method thereof, which is composed of a certain proportion of luffa fiber pulp compound, filler, glue, and antibacterial coating. The steps are: (1) Raw material preparation: weighing the raw material according to the proportion (2) loofah fiber pulp composite pretreatment: loofah is placed in oven to dry, and the dried loofah is soaked with sodium hydroxide solution, rinses loofah fiber with clear water to neutral and then dries; (3 ) Sizing material preparation: take chitosan by weight, add water, gelatinize and cool to room temperature after boiling; (4) paper sheet making: add loofah fiber pulp compound, sizing material, filler in water according to a certain proportion, After stirring, pour into sheet machine and carry out paper copying; (5) surface coating: put the coated paper in a cool place to dry to obtain loofah fiber antibacterial wrapping paper. It is non-toxic, harmless and naturally degradable, has obvious antibacterial effect, the method is simple, and does not require additional process steps, equipment and resource consumption.

Description

technical field [0001] The invention relates to the technical field of papermaking, more specifically to a loofah fiber antibacterial wrapping paper, and also relates to a preparation method for the loofah fiber antibacterial wrapping paper. The antibacterial paper can be used for disposable packaging and shelf-life packaging of products such as fruits (such as grapes, strawberries, etc.), cakes (such as steamed buns, bread, etc.), or as hygroscopic and antibacterial packaging cushion paper in cartons. Background technique [0002] The material traditionally used for food disposable packaging is generally plastic. Although plastic products are light, transparent, and convenient, they have poor degradability, high recycling costs, and great environmental pollution. With the increasing shortage of resources, traditional plastic bags can no longer meet the needs of sustainable social development. With the improvement of people's living standards, consumers put forward higher r...
