The production process of the zipper bag manufacturing machine can be divided into

1. Spunlace: A high-pressure fine water stream is sprayed onto one or more layers of fiber webs to entangle the fibers together, so that the fiber web can be reinforced and has a certain strength.

2. Heat-bonded non-woven bag: refers to the addition of fibrous or powdered hot-melt bonding reinforcement material to the fiber web, and the fiber web is heated and melted to cool and form a cloth.

3. Pulp air-laid non-woven bag: It can also be called dust-free paper, dry-process paper non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses a gas flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.

4. Wet-laid non-woven bag: the fiber raw material placed in the water medium is opened into a single fiber, and the different fiber raw materials are mixed to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is in a wet state. Reinforce the cloth into a cloth.

5. Spunbond non-woven bag: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the web is then bonded, thermally bonded, chemically bonded or mechanically. The reinforcement method makes the web into a non-woven fabric.
