Unbleached full-bamboo paste food packaging body paper and production process

Abstract

The invention discloses unbleached full-bamboo paste food packaging body paper and a production process. The unbleached full-bamboo paste food packaging body paper is prepared from refined bamboo slurry and chemical auxiliary materials, wherein the chemical auxiliary materials comprise the following components in parts by weight: 0.008-0.02 part of aluminum sulfate, 0.018-0.028 part of rosin size, 0.03-0.07 part of talcum powder, 0.0003-0.0006 part of retention aids, 0.0002-0.0005 part of organic micro granules, 0.002-0.004 part of silica sol and 0.0003-0.0005 part of a defoaming agent. Through procedures of paste preparation, chemical auxiliary material preparation and paper making, the body paper for food packaging is made; as the bamboo slurry is adopted as a raw material for making paper, forests are protected, and the process is relatively ecological and environment-friendly; the body paper is free of harmful substances such as organic chlorides or dioxin, and wastewater with organic chlorides is not generated, so that water resource pollution is reduced; and as the bamboo slurry comprises bamboo jade which is capable of preventing and inhibiting bacteria, the body paper is capable of relatively well ensuring health and security of people when being compared with other food packaging paper which is not prepared from bamboo slurry.

Description

technical field [0001] The invention belongs to the field of pulping and papermaking, and in particular relates to unbleached whole bamboo pulp food packaging base paper and a production process. Background technique [0002] At present, the vast majority of bleached food packaging paper on the market is made of wood pulp as the main raw material, and is made by using triple-ply wire paper machines, and the supply of wood is far from meeting the needs of production. The annual clumping bamboo is renewable, contains a lot of bamboo fiber, and proper felling is conducive to the growth of bamboo. [0003] Existing food packaging is in direct contact with food, and needs to meet the requirements of waterproof, oil-proof, tear-resistant and hygienic. Existing food packaging is either polymer packaging bags or wrapping paper. For wrapping paper, the manufacturer maintains The beauty of the wrapping paper usually uses white wrapping paper bleached by chlorine, supplemented by some...
