As bulk bag's fabric is made from a woven material, so the bag is not technically "water proof". Users generally want a coating or lamination as a moisture barrier from condensation or a light amount of water.

A common type of "coating" would be a 1 mil. (30 GSM) lamination of heated semi-clear polypropylene, which is bonded to the fabric. Interior coating is most common in U-Panel style of bags, while circular/tubular bulk bags most commonly have exterior coating.

With a production speed of 100mt/min and an effective usage width of 2100mm our coating line can apply PE and PP coating to fabrics commonly used in our industry.
