Characteristics of heat shrinkable packaging heat shrinkable packaging in addition to the general characteristics of plastic film packaging, but also its unique advantages. After the heat shrinkable film is heated, the film will produce 25% - 70% shrinkage. The film is close to the goods. Because the film is transparent, it can fully show the appearance of the goods and improve the effect of exhibition. The shrink film as a sealing material, without adhesive and adhesive, can be close to the package. The sealing material can also be printed with trademarks, product introductions, etc., so as to improve the effect. Because the film is tightly wrapped around the goods, it can be protected from external impact and has a certain buffering property. When it is used for the packaging of brittle containers, it can also prevent the containers from flying away when they are broken. Rain proof and moisture proof - after heat shrinkable packaging, the upper and lower sides of the goods are wrapped in a complete film cover, even if the goods are stacked in the open air or transported in rainy days, there is no risk of moisture. When the film shrinks, it can produce a certain tensile force, which can reach about 300 kg / cm2. It is especially suitable for the collection and pallet packaging of multiple items or easily scattered items, such as the packaging of glass containers, batteries, cans, ceramics, etc., which have been used in the market. The middle package is omitted or partially omitted, which saves the cost of package and is convenient for long-distance transportation and sales. The tear strength of shrinkage film is large, generally not less than 40kN / m. when there are holes in the shrinkage film, it will not expand or tear, which is conducive to the protection of packaging. The technology and equipment of shrink packaging are simple, easy to operate, easy to realize mechanization, save manpower and material resources, and can partly replace the carton and wooden box packaging.
