Courier Bag Film And Two-color Film

AB Two-layer Co-extrusion Blown Film Machine

The production line of AB two-layer co-extrusion blown film machines produced by our company is suitable for blowing high-density polyethylene, low-density polyethylene and linear low-density polyethylene. The products are widely used in courier bag film and two-color film.

Forced feeding main machine: All main machines of PLASTAR adopt dual-alloy forced-feeding screws that feature excellent hardness and wear resistance. It can still plasticize a large number of particles under the environment of high speed and high pressure. The service life can reach 3-5 times of ordinary screws.

Cone stacking mold: The production line of two-layer co-extrusion blown film machines adopts a two-layer cone stacking mold. We optimize the layout by virtue of thermofluidics and observe the fluid condition with the help of 3D simulation software. We are sure that after a high degree of polishing and coating, each runner has the ability to clean itself under the high pressure and high speed scouring of PLASTAR’s high-speed screws. It will reduce waste in the particle replacement process and shorten the downtime of maintenance.

Advanced automation module: The production line of two-layer co-extrusion blown film machines has advanced automation functions, such as centralized feeding, batching, weight control, and automatic central winding. All functions are integrated on the touch screen, thus simplifying operations and increasing productivity. Packaging of fruits, meat, pickles, etc.
