Pasted valve cement sack is made with our paper yarn bag making machine, which consists of 2 ply sack paper inside and outside, between paper is PVA glued vinylon water-soluble yarn netting, it helps to reinforce the bags. The pasted valve cement sack has good performance of high strength, anti-aging, anti-slipping, moisture proof, high-temperature resistant, eco friendly etc. 

Pasted valve cement sack applies the pressure filling method to load cement swift. And our "micropore technology" generates more than 5,000 micropores every square meters of the cement sack surface which size can be adjusted according to the air pressure. When complete filling, negative pressure inside the cement sack decreases, paper fiber surrounded the micropores seal the micropores and block the cement powder. In this way, exhaustion and moisture-proof problem of cement is solved and cement quality can be assured.

Packaging: The pasted valve cement sacks usually packed 200 pcs/bundle or as per customers' requirements.
