1. Set appropriate temperature on the vacuum machine and hot water tunnel;
3. Make sure the product has not been pressed at the bottom of the bag, and the area of the seal is completely clean;
4. Leave about 5cm space between product and vacuum seal. This is to improve vacuum effect, and also to allow some room for product to expand after freezing (for frozen product);
5. Place vacuum packed product in water at 85-90 degrees Celsius for 1-2 seconds.
1. Longer shelf life: increased barrier means longer shelf life keeping product fresher for longer;
2. Attractive appearance: no edges or wrinkles to enhance product appeal;
3. Less chance of leakages: only one bottom seal so less chance of leakages;
4. No need for post pasteurization while maintaining shelf life, therefore enhancing product flavor and saving costs;
5. Save packaging materials: 40-55um Shrink Bag can do a better job than 80um vacuum.
