According to the production process, it is divided into pe flat pocket, self-sealing bag, chain clip bag, envelope bag, punching bag, handbag, zipper bag and PE film.

1, PE flat pocket is the simplest manufacturing process. After the film is blown by the machine, it is cut into bags on the bag-making machine and sealed at the bottom.

2. The self-sealing bag is a bone strip when the machine blows the film, which can be sealed by hand. With chain Bao Butong, these two kinds of bags are generally easily confused.

3. The chain clip bag is a bag made of PE film and two clips (this clip chain comes out separately). Generally, there are relatively wide indentations on both sides of the bag, but the self-sealing bag does not. The self-sealing bag has few printing colors, and the chain-clamping bag can print complex patterns.

The envelope bag has a tongue like an envelope. Stick a piece of tape on your tongue and fold it to seal the bag. Generally, clothes are used more. The courier bag is actually a kind of envelope bag.

Punching a handbag is to punch a hole at the top of a flat pocket to facilitate the handbag.
