PE heat shrinkable film, as an environmentally friendly packaging material with low cost, high production efficiency, excellent appearance, and efficient logistics, has been widely used in the beverage and beer fields in developed countries. The application in China's beverage and beer industries is also becoming increasingly widespread.

The annual usage of PE heat shrink film in Europe exceeds 400000 tons. The author once visited the third-largest shrink film supplier in Europe, PLATO, whose annual production in 2003 was 55000 tons, of which 28000 tons were printed PE color shrink film, exceeding the production of 27000 tons of unprinted PE shrink film (commonly known as white film or plain film in the industry). Its detailed composition is 28000 tons of printed color film, accounting for 51%; Other: 6100 tons are used for glass bottle packaging, accounting for 11%; 8600 tons are used for packaging paper, accounting for 15%; 8600 tons are used for milk packaging, accounting for 15%; 3700 tons are used for packaging building materials such as bricks and tiles, accounting for 6%.

Since the domestic beer industry banned the use of bundled beer, PE shrink film packaging has emerged in the market at a low cost, and its usage has been increasing year by year; Later, as Coca Cola promoted the use of PE shrink film instead of cardboard packaging in China, it expanded from the beer industry to the beverage industry. With the increasingly fierce competition in the terminal market, the low-cost advantage of PE shrink film packaging is becoming more and more popular among manufacturers. Initially, PE shrink film emerged in the market as a form of transportation packaging. After being transported to the sales terminal, it needs to be broken and sold as a single item. However, in recent years, with the change of purchasing methods, the direct sales trend of collective packaging has become increasingly evident. This requires printing of shrink film to improve the shelf display effect of products, providing packaging manufacturers with a good opportunity to enhance the added value of PE shrink film.
