Unimodal: This is one of the biggest properties of the wrapping. With the help of the film's superior winding force and retraction, the product is tightly and firmly tied into a single unit, making the scattered pieces a whole, and even in an unfavorable environment, the product does not have any looseness and separation, and there is no sharp edges and viscosity., To avoid damage.

Primary protection: Primary protection provides the surface protection of the product, forming a very light, protective appearance around the product, so as to achieve the purpose of dust, oil, moisture, waterproof, and anti-theft. In particular, it is important to wrap the film around the packaging to make the packaging articles evenly stressed and to avoid the damage caused by the uneven force, which is not possible by traditional packaging methods(packaging, packaging, tape, etc.).

Compression fixation: The product is wrapped around the film by the retraction force after the film is stretched, forming a compact, non-space occupied unit whole, so that the tray of the product is tightly wrapped together. It can effectively prevent the misalignment and movement of products in the transportation process. At the same time, the adjustable stretching force can make hard products stick tight and make soft products tighten, especially in the tobacco industry and the textile industry.

Cost-saving: using winding film for product packaging can effectively reduce the cost of use. The use of winding film is only about 15 % of the original box packaging, about 35 % of the thermal shrink film, and about 50 % of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve the packaging efficiency and packaging grade.
