According to different production processes, bag making machines can be divided into:
1. Spunlace: the high-pressure micro water jet to one or more layers of fiber network, so that the fibers are entangled with each other, so that the fiber mesh can be reinforced and has a certain strength.
2. Thermal bonded non-woven bag: refers to adding fiber or powder hot-melt bonding reinforcement material into the fiber mesh, and then heating, melting and cooling to form cloth.
3. Pulp air flow into the net non-woven bag: also known as dust-free paper, dry paper-making non-woven fabric. It uses air flow netting technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fiber agglutinate on the netting curtain, and then the fiber mesh is reinforced into cloth.
4. Wet non-woven bag: the fiber raw materials placed in the water medium are opened into single fiber, and different fiber raw materials are mixed at the same time to make fiber suspension slurry. The suspension slurry is transported to the netting mechanism, and the fiber is netted in the wet state and then reinforced into cloth.
5. Spunbonded nonwoven bag: after the polymer has been extruded and stretched to form continuous filament, the filament is laid into a net, and the fiber mesh is then self bonded, thermally bonded, chemically bonded or mechanically reinforced to make the web into non-woven fabric.
6. Melt blown nonwoven bag: its technological process: polymer feeding --- melt extrusion --- fiber forming --- fiber cooling --- netting --- reinforcement.
7. Acupuncture: it is a kind of dry non-woven fabric. Needle punched non-woven fabric uses the puncture effect of needle to reinforce the fluffy fiber mesh into cloth.
8. Stitching: it is a kind of dry non-woven fabric. Sewing method is to use the warp knitting coil structure to strengthen the fiber mesh, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
Bag making machines can be divided into:
1. Non woven bag series:
Bag Making Machine, non-woven environmental protection bag, non-woven bag, non-woven shopping bag, etc.
2. Non woven bag series: non woven paper bag, environmental protection shopping bag, packaging bag, non-woven bag.
3. Non woven products series: non woven storage box, non-woven storage box, non-woven Suit Cover - non-woven suit set.
4, jewelry bag series: gift bags, rope bags, jewelry bags, velvet bags, perfume bags, pencil bags, jewelry bags, etc.
Plastic bag making machines are generally divided into: high pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags, PVC plastic bags, mainly according to the characteristics of their raw materials. And the use of plastic bags with different raw materials is also different.
1. High pressure polyethylene plastic bags are used for: Food Packaging: cakes, candy, fried goods, biscuits, milk powder, salt, tea, etc.; fiber packaging: shirts, clothing, cotton products, chemical fiber products; daily chemical products packaging.
2. Low pressure polyethylene plastic bags are mainly used for: garbage bags, bacteria bags; convenience bags, shopping bags, handbags, vest bags; fresh-keeping bags; woven bags inside bags.
3. Polypropylene plastic bags are generally used for packaging textiles, cotton, clothing, shirts, etc.
4. PVC plastic bags are mainly used for: gift bags, bags, sewing cotton packaging bags, cosmetics packaging bags; zipper file bags, information bags.
Therefore, customers can choose
Bag making machine and its raw materials according to their own actual situation and different needs.
