1.Double-layer co-extrusion laminated film can prolong the length for preservation of liquid package.
2.The cylinder and the screw stem of the extruder are made of high quality alloy steel with optimum hardness and durable service after precision finishing and nitrogen treatment.
3.The auxiliary machine has a platform working table for making operation easy and is equipped with bubble stabilizing ring.
4.Double-rolling and double-cutting coiling unit adopts torque motor to keep proper tensions and make rolling even and roll-changing easy.
1.The thickness and width of the product can be adjusted during production, so this equipment allows you to produce various specifications about this product.
2.The production speed of film is very fast. Because the equipment is highly automated and the stability during production is very good, it can greatly improve the production efficiency of the film;
3.Easy to operate and easy to maintain. This machine uses a good control system, so it is easy to operate. In addition, the quality of this machine is very good, so it does not need to spend a lot of effort in maintenance.
1.Liquid packing film blowing machines are designed to process plastic materials that are suitable for liquid packaging, such as Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), and other appropriate resins.
2.The machine can be adjusted to produce films with specific thicknesses that provide the necessary strength and barrier properties for containing liquids.
3.Liquid packaging films are often designed with enhanced barrier properties to prevent leakage, maintain product freshness, and protect against external contaminants.
4.The films produced by the machine should be compatible with various sealing methods, such as heat sealing or adhesive sealing, to ensure proper closure of the liquid packaging
