Valve Bag

Kraft paper bags are a type of small, loose packaging container that is non-toxic, odorless, and pollution-free, complying with national environmental protection standards. They offer high preservation and are currently one of the popular eco-friendly packaging materials internationally. Kraft paper bags utilize the high strength and good toughness of kraft paper; additionally, a waterproof film can be coated on one layer of the paper to provide moisture and water resistance. Made from several layers (1 to 4 layers) of natural kraft paper, these bags are suitable packaging materials for product transportation and storage. Due to their quality and high added value, kraft paper bags have gained the trust of many industries. Kraft paper bags are sewn using machines. Typically, our kraft paper bags are sewn in three layers, which is why their toughness is excellent. Regardless of the type of items carried, they can effectively demonstrate their performance. The waterproofing of these kraft paper bags is also quite good, as we use a foreign-imported waterproof film coating. This provides excellent moisture resistance and humidity protection, making them not only aesthetically pleasing but also very trendy.
