1By using two extruders to plasticize and extrude two identical or different materials into a co extrusion composite head, a type of express bag film is produced through co extrusion, which greatly improves the physical properties of the film, increases its strength, and gives the film good barrier and air tightness.

2Adopting advanced continuous rotating machine heads, the products are smooth and uniform, ensuring the quality requirements of subsequent process equipment such as packaging machines and printing machines for films. It is suitable for producing composite pearl films, composite liquid packaging films, insulation films, multifunctional agricultural films, etc. Its application scope is gradually expanding and it is the direction of plastic product development.

Applicable raw materials:LDPETheLLDPE

Usage:
1. Check that the temperature self-control is intact, the heating appliances are intact, and pay attention to timely adjusting the heating temperature at each point within the specified range.
2. Check the traction speed and control the film thickness.
Observe and adjust the uniformity of the film thickness, and ensure that the bending diameter meets the standard.
4. Check the pressure of the air storage cylinder, it should not be too high, but there should be a backup pressure.
5. Check and control the proportion of raw materials and mix them evenly.
⒍ Check for impurities in the raw materials, especially by promptly using a magnet to check for any iron mixed in.
7. Check the lubrication condition of the gearbox position and air compressor cylinder lubricating oil.
Regularly check the temperature rise and mechanical transmission of each operating motor.
