Unitization: This is one of the biggest characteristics of stretch film packaging. With the film super winding force and retraction, the product compact, fixedly tied into a unit that scattered small pieces as a whole, even under adverse environmental products without any loose and separate, and no sharp edge and tack to avoid damage.
Primary protection: Primary protection provide surface protection products, around the product to form a very light protective appearance, so as to achieve dust, oil, moisture-proof, waterproof, anti-theft purposes. Particularly important is the film packaging makes packaged goods even by force, to avoid uneven stress damage to the goods, which is the traditional packaging (bundling, packaging, packaging tape, etc.) can not be done.
Compression fixity: With retraction force stretched Stretch Wrapping the product to form a compact, space unit as a whole, so that the products of each tray packed together tightly, which can effectively prevent the product during transport mutual dislocation and movement, while adjustable tensile force can make hard goods close, so soft goods crunch, especially those with unique packaging effect in the tobacco industry and the textile industry.
