Such as color steel plate, galvanized sheet, glass, stone, carpets, flooring, plastic steel profiles, new decorative materials, plastic products and high-grade furniture. Most of the stretch film products in the early stage of stretch wrap were blown film, first from monolayer to two, then to three.

But now most of the drawing film manufacturers are produced by the method of casting. This is mainly due to the uniformity and transparency of the drawing film produced by the casting process, which can fully meet the requirements of the high rate predrawing die. Then, the single layer and double decayer have no three layers in the choice of material, and the finished product is relatively high, so it is ideal to draw the winding film or select the three layer structure.
