Embodiment Construction

[0019] In modern papermaking industrial equipment, a set of winding bobbins for textile industry is installed above the couch roll in the net part, and a certain number of warp yarns are drawn from the winding bobbins to form a piece of yarn, which passes under the couch roll The wet paper removed from the net surface is led between two rollers with a felt, and the wet paper is further dehydrated by the extrusion of the roller and the water absorption of the felt, and the yarn sheet is closely connected with the paper. Sticky, wet paper after pressing, and then through the surface of multiple cylinders with hot steam inside to dry the paper and cut the roll paper, use a bag making machine to make packaging bags of various specifications, and replace the non-degradable and environmentally polluting packaging bags. Serious plastic thin film packaging bags pave the way for the better implementation of the country's plastic restriction order.

Abstract

The invention relates to a reinforced paper packaging bag and a manufacturing method thereof, belongs to the technical field of paper-making, and aims at providing the reinforced paper packaging bag and the manufacturing method thereof. The reinforced paper packaging bag manufactured according to the manufacturing method provided by the invention has the characteristics of low cost, high warp-directional strength and easiness in degradation. The reinforced paper packaging bag is the first choice for replacing a plastic film packaging bag which is difficult to be degraded and has serious pollution to environment, and paves a material base for implementing the national plastic-limiting order. The manufacturing method of the reinforced paper packaging bag provided by the invention comprises the following steps: a) arranging a set of winding rollers applied to textile industry; b) pulling a warp yarn from the winding rollers, tightly sticking the warp yarn with wet paper, drying, coiling and cutting; and c) preparing the reinforced paper into the packaging bag by using a bag-making machine.

Description

technical field [0001] The invention relates to a reinforced paper packaging bag and a manufacturing method, belonging to the technical field of papermaking. Background technique [0002] Modern papermaking can be divided into main procedures such as pulping, modulation, papermaking, and processing. In the papermaking process, the main work of the papermaking department is to evenly interweave and dehydrate the thin paper materials, and then go through drying, calendering, rolling, cutting, sorting, and packaging. The common processes are: [0003] a. Screening of paper materials. [0004] b. Network department. Make the paper material flow out from the head box on the circulating copper wire mesh or plastic mesh and distribute and interweave evenly. [0005] c. Press section. The wet paper removed from the net surface is led between two rollers with a felt, and the wet paper is further dehydrated by the extrusion of the roller and the water absorption of the felt, and t...
