Stretch Film is used for the sale and transportation of various products, and its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, the film cannot create holes. Since shrink films are often used outdoors, UV anti-ultraviolet agents need to be added. It has the advantages of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided and double-sided adhesive, etc., which can save materials and labor when using it. , Save time, widely used in papermaking, logistics, chemical industry, plastic raw materials, building materials, food, glass and so on.
Stretch film uses and general properties: Unitization: This is one of the biggest characteristics of stretch film packaging. With the film's super winding force and retractability, the product is compactly and fixedly bundled into a unit, so that the scattered small pieces become a whole, and the product has no looseness and separation even in unfavorable environments, and there is no sharp sharpness. edges and stickiness to avoid damage. Primary protection: The primary protection provides surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dustproof, oil-proof, moisture-proof, waterproof and anti-theft. It is particularly important that the stretch film packaging makes the packaged items evenly stressed to avoid damage to the items caused by uneven stress. Compression fixation: With the help of the retraction force of the stretch film, the product is wrapped and packaged to form a compact unit that does not take up space as a whole, so that the trays of the product are tightly wrapped together, which can effectively prevent the transportation process. The mutual dislocation and movement of the products, the adjustable stretching force while stretching the stretch film can make the hard products close to each other and make the soft products compress, especially in the tobacco industry and the textile industry, it has a unique packaging effect. Cost saving: The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve the packaging efficiency and packaging grade.
Stretch film is widely used: bundle box packaging, horizontal mechanical packaging, paper tube packaging, tube and cable packaging, carpet, board, fiberboard, profiled materials and other product packaging.
