Abstract

The invention discloses a loofah sponge fiber antibacterial packaging paper and a preparation method. The packaging paper consists of a loofah sponge fiber pulp compound, a filler, a glue material andan antibacterial coating according to a certain proportion. The steps are as follows: (1) raw material preparation: weighing raw materials according to the proportion for standby application; (2) loofah sponge fiber pulp compound pretreatment: placing loofah sponge in an oven and performing drying, soaking the dried loofah sponge in a sodium hydroxide solution, and washing the loofah sponge fiberwith clear water until neutrality and then performing drying; (3) glue material preparation: weighing chitosan according to a weight ratio, adding water, performing gelatinization after boiling, andperforming cooling to room temperature; (4) papermaking: adding the loofah sponge fiber pulp compound, the glue material and the filler to water according to a certain proportion, performing stirring,and then pouring the mixture into a sheet-making machine to carry out papermaking; and (5) surface coating: putting coated papers in a shady and cool place to perform drying in the air to obtain theloofah sponge fiber antibacterial packaging paper. The packaging paper is non-toxic and harmless, can be naturally degraded, and has obvious antibacterial effects. The method is simple, and no additional process steps, equipment and resource consumption are needed.

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...
