The outer bag is made of brand-new PP woven fabric, equipped with an integrated thickened PE plastic liner without splicing seams and fully heat-sealed, which comprehensively blocks moisture, rainwater and condensation from permeating into the bag from inside.
The soft liner closely fits the outer bag, resisting breakage and shifting during material filling. The liner at the filling spout can be separately tied and sealed to form double-layer moisture locking protection.
The wear-resistant and scratch-resistant outer bag safeguards the liner, with each layer performing its own waterproof and moisture-proof function. The bags support short-term open-air stacking, as well as long-distance ocean shipping and storage in high-humidity warehouses.
Customizable liner thickness options include economical thin versions and heavy-duty thick versions. Liner sealing can be matched for lifting loops and discharge spouts to achieve all-round dead-angle-free moisture isolation.
