Abstract

The invention particularly discloses a production process of a weather-resistant plastic woven bag, and belongs to the technical field of plastic woven bags. The production process of the weather-resistant plastic woven bag comprises the following concrete steps of S1, melting and mixing raw materials; S2, extruding molten materials through an extruder: adding the molten materials into the extruder, extruding the molten materials, and finally forming filiform raw materials, wherein the feeding speed of the molten materials into the extruder is 120 to 130kg / min; S3, weaving to form a bag shape;S4, cutting the dimension; and S5, sealing the cut woven bag: taking out the tubular bag body cut in the step S4, and sealing one end of the cut tubular bag body. Through using weather-resistant adding materials, the service life of the plastic woven bag is longer, and the storage capacity is better; and after the weather-resistant adding materials are added into the plastic woven bag, the resistance to oxidation is remarkably improved, and the service life is remarkably improved compared with an existing plastic woven bag under the environment with direct sunlight.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to a production process of weather-resistant plastic woven bags. Background technique [0002] Woven bag, also known as snakeskin bag. It is a kind of plastic bag, used for packaging, and its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. Weaving density refers to the number of warp and weft yarns in a 100mm×100mm braided fabric. [0003] The national standard GB / T8946-1998 stipulates that "flatten the bag, delineate two squares of 100mm x 100mm at the upper and lower corners of the bag, and the outer side of the square is 100mm away from the edge line of the bag. Visually measure the warp and weft of the square. , taking the average value, and counting when the end point is less than one at the end, it is counted as one." While the weaving density is stipulated in the national standard, the density tolerance is al...
