Abstract

The invention discloses camellia oleifera shell packaging paper and a method for preparing the same. The method includes particular technological steps of (1), carrying out pre-impregnation and steamexplosion treatment on camellia oleifera shells to obtain coarse pulp fibers; (2), screening coarse pulp to obtain fine pulp; (3), carrying out mixing and making on the obtained fine pulp and bleachedneedle wood pulp and squeezing and drying made paper to obtain the camellia oleifera shell packaging paper. The camellia oleifera shell packaging paper and the method have the advantages that makingis carried out on the camellia oleifera shells and the bleached needle wood pulp to obtain the colored paper with the characteristics such as high gas permeability and roughness, the camellia oleiferashell packaging paper can be used as special paper for the field of paper-base packaging, molding, decoration and the like, and accordingly high-valued utilization can be implemented on the camelliaoleifera shells which are agricultural waste materials.

Description

technical field [0001] The invention belongs to the field of wrapping paper, and in particular relates to a camellia oleifera shell wrapping paper and a preparation method thereof. Background technique [0002] With the strengthening of people's awareness of environmental protection, the demand for paper packaging in the packaging field has also increased due to its characteristics of no pollution, no pollution, recyclability, easy processing, and low cost. According to statistics, packaging paper accounts for 55% of my country's paper production. Packaging paper (cardboard) and pulp molding are widely used in food, light industry, chemical industry, medicine, construction and other industries, and have broad development prospects. [0003] Camellia oleifera is a unique woody edible oil tree species in my country, and it is called the four woody edible oil source tree species together with olive, oil palm and coconut. Camellia oleifera husk is the largest by-product in the ...
