Method for producing food packaging paper by using bagasse pulp

Abstract

The invention discloses a method for producing food packaging paper by using bagasse pulp. According to the method, mainly bagasse is used as a raw material and is matched with a small amount of imported softwood pulp board; and the method comprises the following steps: S1, separately pulping bagasse and softwood pulp board to prepare bagasse pulp and softwood pulp; S2, conveying the bagasse pulpand the softwood pulp prepared in the step S1 into a pulp preparation pool, and uniformly mixing to prepare finished pulp; S3, conveying the finished pulp prepared in the step S2 into a pre-papermaking pool of a paper machine, and making the finished pulp into paper so as to finish papermaking; and S4, wetting the surface of the paper prepared in the step S3, carrying out finishing coiling and calendaring drying, and finally slitting by adopting a slitting machine to obtain finished paper. According to the invention, bagasse is adopted as a raw material and matched with a small amount of imported softwood pulp boards, the proportion of expensive long fibers in paper can be reduced, the proportion of bagasse pulp is increased, the production cost is reduced, resources are saved, environmental protection is facilitated, and the produced product is high in quality, stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of papermaking and relates to a method for producing food wrapping paper using bagasse pulp. Background technique [0002] The traditional food packaging paper production uses all wood pulp, however, with the reduction of forest coverage, countries around the world pay more and more attention to the protection of natural ecology and natural environment, so there will be more and more strict restrictions on the harvesting of forest trees, bleaching The output of wood pulp is also showing a downward trend year by year, and the price of pulp is getting more and more expensive. [0003] Due to the increasing shortage of timber resources, its supply price has been rising all the way, and the supply channels are unstable, which puts great pressure on food packaging paper manufacturers. Considering that Guangxi, Guangdong, Yunnan, Fujian and other provinces in southern my country are sugarcane producing areas, suga...
