1. Unitization: This is one of the biggest characteristics of wound film packaging. With the help of the super winding force and retraction of the film.
2. 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).
3. 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 hard products close to each other, making soft products tight, especially in the tobacco industry and textile industry.
4. Cost saving: The use of wound film for product packaging can effectively reduce the use cost. The use of wound 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.
To sum up, the application field of stretch film is very wide, but many fields in China have not been involved and many fields involved have not been widely used. With the expansion of the application field, the amount of stretch film will increase greatly, and its market potential is incalculable. Therefore, it is necessary for us to vigorously promote the production and application of stretch film.
