stretch wrap film, also known as “wrap film”, is made by linear polyethylene LLDPE resin and tackifier special additives in a certain proportion of formula. stretch wrap film is a very popular packaging form in the world. High elasticity, can be wrapped for any geometric shape, and can avoid the damage caused by the strapping. It has good anti-loose, rainproof, dustproof, anti-theft effects, etc. It is widely used in the collection and packaging of articles. And tray packaging for containers (cans), chemicals, ceramics, glass, hardware machinery and equipment, steel, paper, textiles, furniture, food industry (beverage packaging), electronic product boxes and other industries.
There are three main ways to use stretch wrap film
1. Hand-wound film: This is mainly by manual packing. Hand-wound film generally has lower requirements on quality. The weight of each roll is generally around 4KG and 5KG to facilitate operation.
2. Machine wrapping film: The mechanical wrapping method is adopted when the machine uses the wrapping film. The main purpose is to pack the die roll by the movement of the goods. The tensile strength of the film is relatively high, and the stretching rate of the film is also required. The general stretch ratio is required to be 300%, and the product has a coil weight of 15KG;
3. Machine pre-stretch wrap film: This type of wrap film is mainly used for mechanical packaging. When packing, the packing machine first stretches the stretch film to a certain ratio, and then wraps the wrap film around the goods to be packaged. The resilience of the goods tightens the goods, and the product quality is high, with high tensile strength, elongation and puncture resistance;
Henan Yinfeng Plastic Co., Ltd. is currently the private enterprise producing the largest polyethylene plastic film products in Henan Province with the best quality and the most complete product structure. stretch wrap film is made by Yinfeng Company using advanced production technology, with pre-stretching ratio of up to 400%, high anti-buffering strength, good puncture and tear resistance, thin thickness and high cost performance. Over the years, it has been exported to more than 20 countries such as the United States, Mexico, Canada, and Japan, and has been well received by the market.
