PP/PE double-layer co-extrusion sheet machine is one of the main products produced by Qingdao East star Plastic Machinery Co., Ltd. The width of the sheet ranges from 600-3000mm. We can not only produce A+B form, but also A+B+A. We can also fine-tune the width of the product through the die, and the thickness range is adjustable. The products produced by our equipment are evenly layered and have a smooth surface.
