Density and Thickness of Three-layer Co-extrusion Film Blower

The three-layer co-extrusion film blower solves the problems of lotus leaf edge and winding head, thus improving the product quality to a new level. Up rotation refers to a 180 degree round-trip rotation of the traction roll and the herringbone splint and radius operation of the film to eliminate the phenomenon of "rebar" caused by the thickness of the membrane bubbles. The film blowing die head is always stationary.

The downward rotation refers to the continuous 360 degree rotation of the film blowing die while blowing the film. The film is circulated 360 degrees to eliminate the phenomenon of "rebar bulge" caused by the thickness of the membrane bubbles. One traction and the herringbone splint are always stationary. The purpose of both methods is to solve the adjustment method of film "rebar burst" caused by uneven thickness of the film. Temperatures are relative.

With or without pod, sometimes the quality and temperature of regenerated material are different. You can get a bag to start up and then the main engine comes in front of the card, almost not moving. Then you can get its weight and know its thickness by dividing the main engine by width and then by traction, then you can know its density. As long as there is density and thickness. It will be OK in the future, but there are too many uncertainties because these two materials often have to be regenerated, and they also change depending on the temperature. We usually just click on them and add up the radius.

For example, HDPE membranes are commonly used in commercial, grocery and food packaging. PE film processing generally uses ordinary blown film processing or flat extrusion processing. Mainly by adjusting the base speed and the proportion of traction speed, it can be calculated with simple mathematical formula. The die head can only fine-tune the uniformity of the film thickness.
