Abstract

The invention discloses environmentally-friendly package paper. A preparation method comprises the steps of waste paper deinking, vegetable leaf and bagasse treatment, slurry preparation and package paper forming. Wheat straws, waste paper, bagasse, vegetable leaves and waste wood are used as raw materials of the environmentally-friendly package paper, waste materials produced in the industry, agriculture and life are turned into wealth, resources are saved, tree felling is avoided, the environment is protected, and ecological balance is maintained. An environmentally-friendly flame retardant is added into slurry, so that the flame retardant property of the package paper is improved, and packaged articles are better protected. The raw materials are firstly pre-treated by using white rot fungi in the lignin removing process, the lignin removing time and the using amount of hydrogen peroxide are decreased, the hydrogen peroxide can be further used for disinfecting and bleaching the package paper, is safe, non-toxic and green, is environmentally-friendly, does not pollute the environment and achieves multiple purposes in one, and cost is saved. The waste paper, the vegetable leaves and the bagasse are treated by means of a biological method, the treatment effect is good, energy is saved, and the environment is protected.

Description

technical field [0001] The invention mainly relates to a wrapping paper, in particular to an environment-friendly wrapping paper. Background technique [0002] Packaging has two major functions: one is to protect the goods from damage and deterioration during the process of manufacturing, transportation, warehousing and sales; It meets the increasing material and cultural needs of consumers, and promotes and stimulates consumption. As an important packaging material, packaging paper has been widely used in product packaging in various industries. It includes container board and corrugated base paper, white cardboard and white cardboard, beverage flexible packaging paper, special packaging paper, etc. [0003] Waste paper, torn clothes produced in daily life, plastic, glass, sewage and residues produced in industry, and various crop straws produced in agricultural production all contain various fibers. The burning of wheat straw has become a big environmental pollution prob...
