To solve the airtight problem of woven bags.

At present, only micro-holes can be pierced on the surface of color-printed woven bags, and no other technique can be replaced. The color printing woven bag is the same as the packaging bag of other structures. It is necessary to solve the problem of exhaustion of the woven bag, temperature resistance, and moisture protection. The punching title issue is precisely the hub for solving these skills. After the disposal of the color printing woven bag, the gas is repulsed from the inside to the outside during filling, which satisfies the exhaust requirements of the woven bag and also ensures the pass rate of the bag. The packaged bag of the material is closed after the vent hole passes through the belt during the belt conveying process, and the moisture-proof function of the package during transportation and storage is well solved.
