1. Unitization: This is one of the great features of the wrap film packaging. With the film's superior winding force and retractability.

2. Primary protection: Primary protection provides surface protection of the product, forming a very light, protective appearance around the product to achieve dust, oil, moisture, water, and theft. It is especially important that the wrapping film package makes the packaged articles evenly stressed, and avoids damage caused by uneven force. This is not the case with traditional packaging methods (bundling, packaging, tape, etc.).

3. Compression and fixation: The product is wrapped by the retractive force of the stretched film to form a compact, space-saving unit, so that the trays of the product are tightly wrapped together, which can effectively prevent the transportation process. The misalignment and movement of the products in the middle, while the adjustable tensile force can make the hard products close to each other, making the soft products tight, especially in the tobacco industry and the textile industry.

4. Cost-saving: The product packaging can be effectively reduced by using the wrapping film. The 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, improve packaging efficiency and packaging grade. and packaging grade.

In summary, the application field of the wrapping film is very wide, and many fields in China have not been involved yet, and many fields that have been involved have not been widely used. As the application field expands, the amount of the wrapping film will increase greatly. Market potential is immeasurable. Therefore, it is necessary to vigorously promote the production and application of the stretch film.
