PVC shrink film advantages and selection techniques
Jun 15, 2018

The more common types of shrink film are POF, OPS, PETPE, PVC, etc. In comparison, the advantages of PVC shrink film are still more obvious. It not only can assemble bulk goods into a whole, but also applies to single-piece goods packaging. The shrink film is close to the surface of the package, so that the goods are more beautiful, crisp and shiny.


At present, PVC shrink film is mainly used for food and beverage and cosmetics products, because it is non-toxic and non-polluting, used for outer packaging is elegant, smooth, transparent, strong toughness, good sealing, and for durability, preservation, anti- Dust, moisture, loss prevention, anti-pollution have excellent functions and are deeply loved by manufacturers


When choosing a PVC shrink film, consider factors such as the printing method, the shape of the container, and the storage and transportation environment of the product. Different printing methods The printability of inks is different. Flexographic printing and gravure printing are mainly used for PVC shrink film printing. The former mainly uses environmentally-friendly water-based inks, and the latter generally uses solvent-based inks.


Second, the shape of different containers has different requirements for the shrinkage rate of the material. If it is a PVC shrink film, it can meet the requirement of low shrinkage rate and it is an approximately cylindrical container. Because different films have their own surface characteristics, each film requires the use of a specific ink composition in order to obtain suitable properties. However, in order to reduce the number of press cleaning, reduce cross-contamination, and control the amount of ink, general-purpose inks will have a good development.
