Many customers need inner membrane waterproof woven bags, and our Jinhui plastic knitting factory is made of outer film woven bags, then what is the difference between the two, what is the difference in their production process, let us understand.
Waterproof woven bags generally have two kinds: one is the film, one is the inner bag, the film is divided into the inner film and the outer film, the inner film as the name suggests is in the woven bag layer plus a layer of plastic film, the outer film is added on the outside, the following is the principle of the inner membrane: The ordinary woven bag is covered with a film on the surface of the woven bag, and the thickness of the film is generally 5-20 grams per square. In order to moisture-proof, another approach is to add a film bag inside the woven bag. The moisture-proof effect of the first method is not very good, and the woven bag is easy to be scratched, while the second method will cut the inner film bag when the material inside is poured out. Combined with the advantages and disadvantages of the above two methods, the internal membrane woven bag is generally used in the packaging bag of fertilizer products. This kind of woven bag is to compound the polyethylene film in the inner layer of the woven bag at high temperature, and the polyethylene film of the composite layer is between 20 grams and 50 grams per square, and the bag body is thick, sturdy and durable, and is not easy to scratch. The above is the main difference, I hope to have a certain help to the woven bag factory.
