With the development of the packaging industry, polyethylene stretched film holds the most advantageous position in the packaging industry. Polyethylene stretch film can tightly wrap goods into a whole, reducing damage, collapse, and unpacking during storage and transportation. The product is packaged with polyethylene film, which is waterproof, dustproof, and transparent. It can easily distinguish the types of packaged goods. Used in the logistics industry, mainly for environmental protection, easy to use, and not easy to come off. So what are the advantages of polyethylene stretch film as a packaging material?
1. According to the characteristics and application scope of different types of stretching films, the method of polyethylene stretching film was selected. The stretching film is stretched according to a predetermined stretching ratio and wrapped on a pallet of goods. The advantages of stretching film are uniform coating, beautiful packaging, and strong adaptability (both ultra-light and ultra-high goods can be used). Under the same conditions, the material consumption of the stretching film decreased by 3050%, resulting in a slower pulling speed of the stretching film compared to the pulling speed of the tray, and a slower rotation speed of the goods.
2. PE stretching film has developed from a single layer to two or three layers, and now it is mainly produced by casting method. PE stretch film is a material with good toughness and is not easily crushed with ordinary plastic crushers. Due to the softness and toughness of the PE film, it is not easy to cut, let alone the high tool temperature at high speeds, which can cause LDPE to melt and adhere to the blade. PE granulation can be directly put into the feeding port of the extruder in strips, and the PE film is pulled into the barrel by the shear force of the screw to heat, melt, and extrude for granulation.
3. The complete appearance of stretched film is a thin and transparent film. Due to its excellent transparency, consumers can directly.
