How does the square bottom valve bag solve the moisture-proof problem after cement filling?

The packaging bag filled with cement will automatically close after the vent hole contacts the belt during the conveying process of the contact belt, which better solves the moisture-proof performance of the cement packaging in the process of transportation and storage.

Anhui Tianda Environmental Protection New Material Co., Ltd. mainly produces square bottom valve bags, inner-coated woven bags, outer-coated woven bags, color-printed woven bags, paper-plastic three-in-one bags, flexible container bags, PE bags, FFS film, mesh Eye bags, plastic woven bags, polypropylene raw materials, etc.
