What is features and applications of stretch film ?

　　PE stretch film (also known as roll film) has high tensile strength, tear strength, and good self-adhesive properties, which can wrap objects together to avoid loosening during transportation. The film has excellent transparency, wraps objects beautifully, and makes objects waterproof, dustproof and anti-breakage. 　　Specific features of stretch film (winding film). 　　1. Unitization: This is one of the great characteristics of winding film packaging. The extremely strong winding force and shrinkage of the film make the product compactly and fixedly tied into a unit, and the small scattered parts are combined into one, so that the product will not be loosened and separated even in an unfavorable environment, without sharp edges and adhesiveness, and will not cause damage. 　　 2、One-time protectiveness: One-time protectiveness provides product surface protection and forms a slight protective appearance around the product to achieve the purpose of dustproof, oilproof, moistureproof, waterproof, and anti-theft. It is especially important that the winding film packaging should apply force evenly to the packaged items to avoid uneven force causing damage to the items. This is what the traditional packaging methods (strapping, wrapping, tape, and another packaging) cannot do. 　　 3、Compression and fixity: Wrap the wrapped products with the contraction force after stretching the wrapped film to form a whole machine with compact structure and not occupying space, and wrap each pallet of the products, which can effectively prevent the misalignment and movement of the products during transportation, and at the same time make close contact with the hard products with adjustable stretching force to make close contact with the hard products 　 　4、Saving cost: Using winding film for product packaging can effectively reduce the use cost. The use of winding film is only about 15% of the original box packaging, about 35% of the heat-shrinkable film, and about 50% of carton packaging. At the same time, it can reduce the labor intensity of workers and improve packaging efficiency and packaging grade. Application areas of stretch film (winding film). 　　 Stretch film (also known as rolled film) is mainly used with pallets to replace small containers with fragmented goods for packaging. As it can reduce the transportation packaging cost of a large number of goods by more than 30%, it is widely used for bulk packaging of numerous products in industries such as electronics, building materials, chemicals, metal products, auto parts, wires, and cables, daily necessities, food and paper. In warehouse storage, in order to save space and floor space in foreign countries, most of the packaging of stretch-wound film pallets are used for three-dimensional storage and transportation.
