Problems solved by technology

It usually has high strength and toughness, can withstand pressure and folding, and the quality requirements are simpler than paper types such as cultural printing paper. However, with the improvement of people's living needs, the market demand continues to increase, and a large amount of waste paper is produced. It causes waste of resources. Recycled paper, as a green, energy-saving and environmentally friendly material, has become an important part of paper packaging. However, how to improve the performance of recycled paper has become the main problem to be solved.

Abstract

The invention discloses a production technology of wrapping paper. The production technology comprises the following steps: step one, preparing raw materials: sorting impurities, viscose paper, binding needles and packaging tape of a raw pulp plate or waste recycled paper for later use; step two, repulping: repulping the raw materials by an aquapulper; step three, preparing pulp: putting the repulped raw materials into a pulp blending pool, adding a wet strength agent, oxidized starch and ammonium stearate and fully stirring a mixture by using a pulp stirrer mounted on the pulp blending pool;step four, supplying the pulp: transporting the pulp to molding equipment on a production line through a pulp supplying pump; step five, manufacturing paper with pulp: manufacturing the pulp, adding to a net, squeezing, drying, calendaring and coiling; and step six, molding: processing the paper into a needed shape through a die-cutting machine. The wrapping paper produced by the production technology disclosed by the invention has relatively high plasticity and flexibility; the wear resistance, folding resistance and anti-aging degree of the wrapping paper are improved; and meanwhile, the reusability of waste paper resources is also improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process of wrapping paper. Background technique [0002] Wrapping paper is a general term for a type of paper mainly used for packaging purposes. It usually has high strength and toughness, can withstand pressure and folding, and the quality requirements are simpler than paper types such as cultural printing paper. However, with the improvement of people's living needs, the market demand continues to increase, and a large amount of waste paper is produced. The waste of resources has been caused. As a green energy-saving and environmental protection material, recycled paper has become an important part of paper packaging. However, how to improve the performance of recycled paper has become the main problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a production process for wrapping paper in order to solve ...
