POF shrink film products have good airtightness and long service life.

Convenience in life is a trendy buzzword, and it is the main theme of the continuous development of our society. Among the products used for packaging, heat shrinkable film is a good film packaging material. It has many advantages, but it also has some disadvantages. It is necessary to consider that the shrinkage rate of the graphic image is the same as the shrinkage rate of the heat shrinkable film, so that the ink used in the heat shrinkable film label printing must have a certain shrinkage rate to accurately reproduce the image and text. Since heat shrinkable film labels must undergo shrinkage during the printing process, and barcodes can only be read with accurate reproduction, they must undergo strict design and printing quality control. Otherwise, the bar code quality will be unqualified or cannot be read after the pattern shrinks and deforms. The printability of most heat shrinkable films is not very good, and pre-press pretreatment is required. POF shrink film products have good airtightness and long service life, but after opening the can, because the edges of the easy-pull lid and iron lid have begun to contact the natural space, the natural oxidation process may lose the original protection and safety. The better choice is to use a well-sealed glass packaging box, place it in the freezer of the refrigerator, and then enjoy the opened canned food as soon as possible. The lifestyles of modern people are changing rapidly and with each passing day, and the requirements for various products needed for daily life are getting higher and higher. How should we correctly recognize and use modern POF shrink film products? POF shrink film manufacturers can produce modern products that are convenient, beautiful, and affordable, so that consumers can use them with confidence and joy. But because it is easy to oxidize after opening the can, a better choice is to put the opened food in a well-sealed glass box, and then place it in the freezer of the refrigerator, and then enjoy the opened canned food as soon as possible. Enjoy modern life.
