The winding film, also called stretch film and thermal contraction film, is produced by taking PVC as a base material and DOA as a plasticizer and having self-adhesion function at home at first. Due to environmental problems, high cost, poor stretchability and the like, the PE stretch film is gradually eliminated.
The PE stretch film firstly uses EVA as a self-adhesive material, but has high cost and taste, and later develops PIB and VLDPE as self-adhesive materials, the base material is mainly LLDPE at present, the existing PE winding film is a material with good toughness, and has high tensile strength and tear strength and good self-adhesion, so that an object can be wrapped into a whole, and the object is prevented from scattering and collapsing during transportation. The wrapping object is attractive and elegant, the object can be prevented from being waterproof, dustproof and damaged, and particularly, the wrapping film is used for packaging to enable the packaged object to be stressed uniformly, so that the object is prevented from being damaged due to uneven stress, which cannot be realized by the traditional packaging mode (bundling, packaging, adhesive tape and the like), the wrapping film is used for packaging products, and the use cost can be effectively reduced. Therefore, the winding film can form a light and protective appearance around the product, thereby achieving the purposes of dust prevention, oil prevention, moisture prevention, water prevention and theft prevention.
With the expansion of the application field, the dosage of the stretched film must be greatly increased, and the market potential of the stretched film is immeasurable. It is necessary to greatly popularize the production and application of stretch films. However, the winding film on the market has a problem that the winding film has low tensile strength and is easy to break.
