Production process of woven plastic bags

The raw materials of woven plastic bags can be divided into brand new materials (pure transparent, semi-transparent (typically white), and fully recycled materials (gray, or grass green, such as logistics woven bags). Of course, there will be differences in price. When purchasing, you should choose the right type. Next, Anhui Tianda Environmental Protection New Material Co., Ltd. sells the production process of some woven plastic bags.

1. The whole roll of qualified plastic woven cloth is released by the unwinding machine, and the whole cloth mechanism evenly covers it on a metal tube, and then the blown film into a roll is placed on the inner membrane platform at the other end of the metal tube and passed through the metal tube to the other end of the metal tube. At the same time, the woven cloth covered on the metal tube is pulled out together, and then pulled by two active traction machines placed at both ends of the heat oven, The two ends of the tractor are pressed tightly by the rubber roller of the tractor to form a closed space.

2. Then inflate the inner membrane gap to make the inner membrane and the outer woven bag expand into a tubular air bag, so that the outer layer of the inner membrane is close to the inner surface of the plastic woven cloth.

3. After being heated by a hot oven to soften the adhesive layer of the outer layer of the inner membrane, it forms a bond with the inner surface of the woven cloth under the effect of the air pressure of the air bag to make it a whole. Finally, the composite plastic woven cloth of the inner membrane is rolled into a whole roll by inserting or not inserting the edge and then transferred to the bag making process.
