Antiskid film coating woven bag

Abstract

The invention discloses an antiskid film coating woven bag which is formed by a plastic woven cloth in cutting and sewing modes. The outer surface of the plastic woven cloth is coated with a plastic film layer, and stripe-shaped protrusions which are formed through extrusion are arranged on the surface of the plastic film layer. The stripe-shaped protrusions placed in the middle of the plastic woven cloth are composed of a plurality of sloping grains which are distributed in the width direction of the plastic woven cloth, the directions of the adjacent sloping grains are opposite, and the width of the stripe-shaped protrusions placed in the middle of the plastic woven cloth is 0.5-0.6 the width of the plastic woven cloth. The stripe-shaped protrusions placed at the two ends of the plastic woven cloth are composed of a plurality of straight grains which are evenly distributed at intervals in the length direction of the plastic woven cloth. The antiskid film coating woven bag is simple in structure, and reasonable and novel in design, increases the friction force between bags, achieves an antiskid effect, prevents stack collapse, omits a bag overturning process, lowers the defective percentage, lowers production cost and reduces the amount of labor.

Description

technical field [0001] The invention relates to a woven bag, in particular to a non-slip coated film woven bag. Background technique [0002] At present, most of the woven bags used in domestic automatic packaging lines are coated woven bags. Due to the smooth surface of the coated woven bags, the products are easy to collapse after packaging. In order to solve the problem of collapse, the existing coated woven bags use the following three types: Method for anti-slip treatment: First, after the woven bag is coated, the bag is turned over, and the coated side is turned over to the inside of the bag. However, the bag turning process is added, and the production cost is increased by manual bag turning and machine turning bag, and the efficiency is relatively low. Low; second, stick the middle seam after coating the woven plain cloth, and put the coated side on the inside. However, the woven plain cloth is 30-50mm wider than the finished product, and it will be cut off after coa...

Problems solved by technology

[0002] At present, most of the woven bags used in domestic automatic packaging lines are coated woven bags. Due to the smooth surface of the coated woven bags, the products are easy to collapse after packaging. In order to solve the problem of collapse, the existing coated woven bags use the following three types: Method for anti-slip treatment: First, after the woven bag is coated, the bag is turned over, and the coated side is turned over to the inside of the bag. However, the bag turning process is added, and the production cost is increased by manual bag turning and machine turning bag, and the efficiency is relatively low. Low; second, stick the middle seam after coating the woven plain cloth, and put the coated side on the inside. However, the woven plain cloth is 30-50mm wider than the finished product, and it will be cut off after coating, which will waste a lot and increase the stickiness. The middle seam process; third, when weaving woven bags, the flat yarn is folded, and the coating film is relatively thin. The uneven surface of the woven bag is used to increase the friction, which reduces the output of the woven bag and affects the aesthetics of the product.
