Hand wrapped film

With the development of the packaging industry, polyethylene stretch film occupies the most advantageous position in the packaging industry. Polyethylene stretch film can tightly wrap goods into a whole, reducing damage, collapse, and unboxing during storage and transportation. The product is packaged with polyethylene film, which is waterproof, dustproof, and transparent. It can easily distinguish the variety of packaged goods. Used in the logistics industry, mainly for environmental protection, convenient to use, and not easily detached. So what are the advantages of polyethylene stretch film as a packaging material?
1. Based on the characteristics and application scope of different types of stretch films, the method of polyethylene stretch film was selected. After stretching the stretch film according to the pre-set stretching ratio, it is wrapped on the pallet of goods. The advantages of stretch film are uniform coating, beautiful packaging, and strong adaptability (ultra light, 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 stretch film has evolved from single-layer to two-layer and three-layer, and now it is mainly produced by casting method. PE stretch film is a material with good toughness and is not easily crushed by ordinary plastic crushers. Due to the softness and toughness of the PE film, it is not easy to cut, and the high temperature of the cutting tool at high speeds can cause LDPE to melt and adhere to the cutting edge. PE granulation can be directly placed 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 stretch film is a thin and transparent film. Due to its excellent transparency, consumers can directly see the product information when packaging products, dispelling their doubts and increasing sales volume. It is precisely because of this that it has occupied an indelible position in the packaging industry.
