PVC shrink film can be divided into printing level and ordinary packaging level. Printing grade PVC shrink film, as its name implies, is used for printing and can be processed into printed labels. The vast majority of beverages on the market use PVC labels, such as those used on black tea, green tea, and mineral water bottles. Ordinary packaging grade PVC shrink film can be made into tubular film, L-shaped fold film according to requirements, and can be processed into tube bags and flat bags. http://www.xfhlabel.com/
