Polyolefin Shrink Film Roll

Polyolefin shrink film roll is one of the more popular heat shrinkable materials in the world. PE heat shrinkable film is polymerized from ethylene, and can be divided into high-density polyethylene, medium-density polyethylene and low-density polyethylene according to different densities. Polyolefin shrink film roll is a kind of tough, highly transparent heat shrinkable film with two-way shrinkage. The shrinkage path is stable and balanced during the packaging process, including soft corners after completion, toughness, low temperature resistance, and no hardening. It effectively protects the packaged items, does not produce harmful gas during use, and can meet the requirements of most automatic and semi-automatic machines. It is an economical and affordable product. The heat shrinkability of the film was applied as early as 1936. At first, the rubber film was mainly used to shrink the perishable food. Today, heat shrink technology has been developed to the point that almost all kinds of goods can be packaged with plastic shrink film. In addition, shrink packaging is also used to make shrink labels and shrink bottle caps, so that containers that are not easy to print or have complex shapes can be labeled. Recently, newer application areas have been developed. Production technology and characteristics: The production of shrink film usually adopts extrusion blow molding or extrusion casting to produce thick film, and then stretches longitudinally and transversely at a high elastic temperature above the softening temperature and below the melting temperature, or Only stretch orientation in one direction, but not stretch in the other direction, the former is called biaxial stretch shrink film, while the latter is called unidirectional shrink film. When in use, when the stretching temperature is greater than or close to the stretching temperature, the packaged goods can be wrapped with reliable shrinkage force.

Product advantages of Polyolefin shrink film roll:

It not only overcomes the disadvantages of poor low temperature resistance and demanding storage conditions of PVC heat shrinkable film, but also avoids the disadvantages of poor tear resistance of PP heat shrinkable film and large haze of PE shrinkable film. Comprehensive properties of low temperature, high strength and rubbing resistance.
