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.
 
Cement sacks are available in different sizes and styles upon your request.
The sack is also good for packing other powder building materials, like coating, putty powder, mortar etc.
