3. Make sure the product is not pressed against the bottom of the bag and the sealing area is completely clean; 

4. Leave about 5cm of space between the product and the vacuum seal. This is to improve the vacuum effect and also to allow the product to have a certain expansion space after freezing (for frozen products); 

5. Put the vacuum-packed product into the water for 1-2 seconds.

The advantages of shrinkage: 

1. Longer shelf life: the increased barrier means longer shelf life, making the product fresher and longer; 

2. Beautiful: no edges, no wrinkles, and enhanced product attractiveness; 

3. Less chance of leakage: only One bottom seal, less chance of leakage; 

4. No need for post-pasteurization while maintaining the shelf life, thereby enhancing product flavor and saving costs; 

5. Saving packaging materials: 40um Shrink Bag is better than 80um vacuum.
