General Properties Of Shrink Film

Unitization: This is one of the biggest characteristics of wound film packaging. With the help of the super strong winding force and retraction of the film, the product is tightly and fixedly bundled into a unit, so that the scattered small pieces become a whole. Even under adverse circumstances, the product is free of any looseness and separation, degree, sharp edges and stickiness, so as to avoid damage.

Primary protection: 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 dust, oil, moisture, water and theft prevention. What is particularly important is that the wrapping film packaging can make the packaged articles bear uniform force to avoid damage to the articles due to uneven force, which is impossible for traditional packaging methods (binding, packaging, tape and other packaging).

Compression fixation: The product is wound and packaged with the help of the retraction force after the winding film is stretched to form a compact, non space occupying unit as a whole, so that the pallets of the product are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the products during transportation. At the same time, the adjustable tensile force can make the hard products close to each other, making the soft products tight, especially in the tobacco industry and textile industry, which has a unique packaging effect.

Cost saving: The use of winding film machine 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 the carton packaging. At the same time, it can reduce labor intensity of workers, improve packaging efficiency and packaging grade.
