Common use 1: fine powder
Flexible BCL bags with a membrane and leakproof strip are ideal for a wide variety of powder products, but when leakproof strips are not sufficient to prevent the leakage of fine products from the sewing thread, the use of polyethylene inner bags is a good solution. The inner bag can be purchased separately and placed into the container bag, or the container with the inner bag can be purchased, so that the packaging process will be a little more efficient. The inner bag also provides the function of a moisture barrier layer, which can both keep moisture in the bag and block external moisture, which is very important for fine powder products.
