Shrink packaging is one of the more advanced packaging methods in the market. It uses packaging film or packaging bag to wrap the product on the outside. After heating, the shrink film or shrink bag wraps the product tightly, fully displaying the appearance of the item, improving the product's displayability, increasing the Aesthetics and sense of value. At the same time, the packaged items can be sealed, moisture-proof, pollution-proof, and protect the goods from external shocks. Moreover, heat shrink packaging with oxygen barrier properties can also greatly extend the shelf life of the product.
The benefits of using shrink wrap
1. Shrinkage helps to reduce excess material outside the package, making the package closer, more beautiful in appearance, and improving the attractiveness of meat sales;2. Shrinkage eliminates the wrinkling of the film of the packaging bag and the capillary water absorption caused by it, thereby minimizing the leakage of liquid from the meat;
3. Shrinkage can increase the thickness of the packaging bag, thereby improving its oxygen resistance and prolonging the shelf life of fresh meat. At the same time, it also makes the packaging bag more tough and wear-resistant;
4. The sealing strength of the bag can be improved after shrinking;
5. After shrinking, the packaging bag is closer to the meat, forming a "second skin". If the packaging bag is accidentally damaged, it can significantly reduce the impact on the meat and minimize the loss.

Tips: High-barrier packaging can block the entry and exit of oxygen, carbon dioxide, and water vapor, and play a role in better quality, freshness and shelf life of food.
Choose the right shrink bag based on different uses
1. Choose the right size bag, such as poultry, meat, tuna, etc. If the shrink bag is too large, it will not only cause waste, but also objectively affect the effect of shrinkage. On the other hand, bags that are too small will be marketed to consumers, resulting in a bad consumer experience.
2. When filling, there should be some gaps at the bottom and both sides of the bag to facilitate vacuuming, and the product should not be packed too tightly.
3. Use PB series Barrier Bag for fresh meat or refrigerated meat to ensure a longer shelf life. Frozen meat is selected from SE series, which is resistant to low temperature and puncture, and can effectively prevent the meat from being frostbitten.
