What Are The Benefits Of Heat Shrinkable Film To The Product?

Automotive Shrink Film Suppliers explain to everyone the advantages of heat shrinkable film:

Heat Shrinkable Film is a kind of packaging film with transparent gloss, high shrinkage, environmental protection, safety, and strong tear resistance. During the production process, it is stretched into various shapes regardless of the stretching orientation, so as to adapt to various shapes of products. Packaging, heat-shrinkable film packaging is tightly attached to the surface of the product, forming a transparent and sealed film on the surface, which is firmly wrapped around the periphery of the product, like a protective film.

The PVC Shrink Film is not only beautiful and elegant, save packaging costs, but also can be packaged for promotion, etc., and are sealed, dust-proof, moisture-proof and anti-theft. It has the following four characteristics:

1. Absorbed foreign technology, combined with the domestic status quo, with unique creativity, automatic assembly, sorting, lamination, and thermal shrinkage of various packaging materials, thus overcoming the overlap caused by the easy jitter of similar domestic machines. Insufficiency such as unstable installation, easy-to-card machine, and inadaptability to light, thin and small box products broadens the scope and ability of the machine in the packaging field.

2. A large number of accessories from well-known international companies are used. The electrical components of the whole machine all adopt OMRON, NORGREN and other world-famous brand components. The equipment runs stably and reliably and has won praise from customers in related industries.

3. It can run independently to complete the middle packaging of the small box, or it can be connected with the front-end boxing machine and the back-end with the cartooning machine, without adding special mechanical devices.

4. The packaged product has a smooth and neat appearance, tightly wrapped, and firm welds

For commodity manufacturers, guaranteeing the quality of their products is a necessary condition, and how to make their products stand out among many competitors has become the key to development. Shrink film is generally transported by car: As for transportation and storage, the aspects that need attention are roughly the same. At present, shrink films on the market basically refer to heat shrink films. Therefore, the temperature has a very large impact on the shrink film, which is therefore important in transportation and storage. The point is to manage the temperature. Generally, the distance is more than 5m. Although the shrink film can protect the product, it is necessary to avoid the sun and rain during transportation and storage before use, which will shorten the shrink film's expiration time.

The heat shrinkability of the film has been applied as early as 1936. At first, rubber film was mainly used to shrink packaging perishable food. The shrink film has a single direction of heat shrinkage, and the shrink film has good wear resistance and high strength and can accept the weight of the content. Shrink film is a kind of thermoplastic film that is stretched and oriented during production and shrinks by heat during use. Heat shrinkable film label is a kind of film label printed on plastic film or plastic tube with a special ink. During the labelling process, when heated (about 70℃), the shrinkable label will quickly follow the outer contour of the container Shrink, close to the surface of the container, heat-shrinkable film labels mainly include shrink sleeve labels and shrink-wrap labels. Shrink sleeve label is a cylindrical label made of the heat-shrinkable film as the base material after printing. It is easy to use and is very suitable for special-shaped containers. Shrink sleeve labels generally require special labelling equipment to cover the printed sleeve on the container. At first, the labelling equipment opens the sealed cylindrical sleeve label, and sometimes it may need to punch; then, the sleeve label is cut into a suitable size and sleeved on the container; then heat treatment is performed using steam, infrared or hot air channels, Make the sleeve label tightly attached to the surface of the container. Due to the high transparency of the film itself, the label has a bright colour and good gloss. However, because it needs to undergo shrinkage during use, there is a disadvantage of pattern deformation, especially for products with printed barcodes. Need to go through the strict design and printing quality control, otherwise, the bar code quality will be unqualified after the pattern is deformed. Shrinkwrap labels can be labelled with traditional labelling equipment, which requires the use of adhesives and higher temperatures during the labelling process. In the shrinking process, since the adhesive at the overlapping part of the film will produce stress, hot melt adhesive is better.
