The principle of Food Grade Heat Shrink Wrap is a widely used technology in the packaging industry, which heats the film shrink to tightly wrap the item, achieving a protective and aesthetically pleasing effect.
Food Grade Heat Shrink Wrap is a thin film made of polyolefin materials, which has a certain degree of elasticity and shrinkage sex. When the heat shrink film is heated, the internal thermal motion of the molecules is enhanced, and the interactions between molecules are enhanced reduce the force, causing the film to contract. The shrinkage rate of heat shrink film depends on the material of the film factors such as material, thickness, and heating temperature.
Meat food heat shrinking machine is one of the more advanced packaging methods in the market. After heating, the shrinking film shrinks and wraps the product or package. It can be used for heat shrinkage of high-grade beef, mutton, and fresh meat after vacuum packaging to improve product appearance, improve product grade, and increase aesthetics value.
In the packaging industry, Heat Shrink Wrap is usually used to package various items, such as food, medicine cosmetics, electronic products, etc. During the packaging process, first place the item in the packaging bag, and then afterwards, the heat shrink film is placed outside the packaging bag, and then heated to shrink the heat shrink film, thereby bagging and items are tightly wrapped together.
1. Wide scope of application: Heat shrink film can be applied to various shapes and sizes of items, with excellent strong adaptability.
2. Good protection: Heat shrink film can effectively prevent oxidation and microbial invasion, thereby extending long shelf life of items.
3. Clean and sanitary.
4. Environmentally friendly and beautiful, cost saving.
