Is the container bag waterproof?
There are many wrong information on the Internet about the waterproof performance of flexible container bags. Today we come to clarify the fact that flexible container bags are not waterproof. Flexible container bags are made of woven polypropylene sheeting, which is not waterproof.
Some container bags are coated with polyethylene film, which can be on the outside or both sides. This film does not guarantee the waterproof of flexible container bags. It would be a mistake to think that the coated container bags are waterproof. The polyethylene film can act as a good moisture barrier, and can greatly prevent the leakage of fine raw materials. Again, the film cannot guarantee the waterproof of flexible container bags. The answer to whether flexible container bags can be waterproof is no.
