PVC winding film and PE winding film, as winding film, sometimes have general functions, such as packaging wires and binding small pieces, not only choose the users of PVC winding film, but also choose the users of PE winding film. In terms of stability, it is more stable and will not change the status quo because of the temperature. PE wrapping tray, in the process of shipping, will affect its existing properties due to the change of temperature, and even release plasticizers due to high temperature, resulting in insects sticking to the tray.

In terms of cost, it is more economical. Because its thickness can reach 2 wires, and PE is generally more than 3 wires, in addition, PE winding film has a lower proportion, under the same weight, its metre number is longer, and its tensile performance is better than PE, so it is more affordable in terms of the packaging cost of a single pallet. It is necessary to have certain strength and toughness, to have enough viscoelasticity, to stretch the wrapped film, to have enough capacity and to keep it for a long enough time without relaxation, and to have certain viscous and good stretchability on one-sided or two-sided surfaces.
