Split winding film

PE slitting and wrapping film, elastic film or wrapping film, with self-adhesive properties, is a type of plastic film that can be stretched and tightly wrapped around the packaged item on one or both sides. The self-adhesive adhesive does not adhere to the surface of the packaged item, but only exists on the surface of the film and film.
In the early stage, LLDPE stretch films were mainly blown films, developing from single-layer to two-layer and three-layer; Currently, the production of LLDPE stretch film is mainly based on the casting method, as shown in the following figure. This is because the casting line production has the advantages of uniform thickness and high transparency, which can be applied to the requirements of high magnification pre stretching. Due to the inability of single-layer casting to achieve single-sided adhesion, the application field is limited. Single layer and double-layer casting do not have as wide material selection as three-layer casting, and the formula cost is also high, so a three-layer co extrusion structure is still more ideal. High quality stretch film should have characteristics such as high transparency, high longitudinal elongation, high yield point, high transverse tear strength, and good puncture performance.
Advantages of using split wound film:
·Width can be selected according to specific circumstances, with high cost-effectiveness
·Easy to use and high efficiency
·High buffering strength
·Good shrinkage rate
·Anti puncture
·Good tear resistance
