1. Unitization: This is one of the biggest characteristics of stretch film packaging. Thanks to the film's superior winding force and retraction.
2. 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 dustproof, oil-proof, moisture-proof, waterproof and anti-theft. It is particularly important that the stretch film packaging makes the packaged items evenly stressed and avoids damage to the items caused by uneven force, which cannot be done by traditional packaging methods (bundling, packing, tape, etc.).
3. Compression fixity: With the help of the retraction force after stretching the stretching film, the product is wrapped and packaged, forming a compact, space-free unit as a whole, so that the product pallets are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the products during transportation, and the adjustable tensile force can make the hard product close and the soft product tight, especially in the tobacco industry and the textile industry, which has a unique packaging effect.
4. Cost saving: the use of stretch film for product packaging, can effectively reduce the cost of use, the use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.
To sum up, the application field of stretch film is very wide, and many domestic fields have not been involved, and many fields have not been widely used, with the expansion of the application field, the amount of stretch film will grow greatly, and its market potential is immeasurable. Therefore, it is necessary to vigorously promote the production and application of stretch film
