上海Three layer coextrusion film blowing machine

The three-layer coextrusion film blowing machine is installed. The three-layer coextrusion film blowing production line adopts new high-efficiency and low-energy consumption extrusion unit, IBC film bubble internal cooling system, ± 360 ° horizontal up traction rotation system, photoelectric automatic deviation correction device, full-automatic winding and film tension control, computer screen automatic control system and other advanced technologies.

The non-woven fabric is also a kind of polymer short fiber chemical material. It has high tensile strength and extensibility through acupuncture or hot bonding. After it is combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of the non-woven fabric, which is conducive to the stability of the composite geomembrane and protective layer. This film can be widely used in light and heavy packaging because of its good barrier, fresh preservation, moisture resistance, frost resistance, oxygen resistance and oil resistance. Such as all kinds of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies, etc. Its main mechanism is to block the leakage channel of earth dam with the impermeability of plastic film, bear water pressure and adapt to dam deformation with its large tensile strength and elongation.
