Unitization of packaging materials: This is one of the biggest characteristics of winding film packaging. With the help of the super winding force and retraction of the film, the product is compactly and fixedly bound into a unit, so that the scattered small parts become a whole. Even in an adverse environment, the product has no looseness and separation, and there is no sharp edge and viscosity, so as to avoid damage.

Primary protection: primary protection provides the 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. It is particularly important to wrap film packaging to make the packaged articles bear uniform force and avoid damage to the articles caused by uneven force, which can not be achieved by traditional packaging methods (binding, packaging, tape and other packaging).

Compression fixity: the product is wound and packaged with the help of the retraction force after the stretching of the winding film to form a compact unit without occupying space, 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 together and tighten the soft products, Especially in the tobacco industry and textile industry, it has a unique packaging effect.

Cost saving of packaging materials: the use of winding film 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 the labor intensity of workers and improve the packaging efficiency and packaging grade.
