Food vacuum packaging bag is the first striking visual effect of food, food vacuum packaging bag design is beautiful, atmospheric and advanced. The probability of customers considering buying is particularly high.
Food vacuum packaging bags, also known as decompression packaging, is the packaging container of air all out of the seal, so that the bag to maintain a high state of decompression, air scarcity is equivalent to the low oxygen effect, so that microorganisms have no survival conditions, to achieve the purpose of fresh fruit, no disease and rot. Because the fruit is fresh food, still breathing, high lack of oxygen will cause physiological disease, so the fruit rarely use vacuum packaging.
In addition to the vacuum packaging has the function of oxygen removal and quality preservation, the main function of vacuum food packaging also has the function of anti-pressure, gas barrier, freshness, etc., can more effectively make the food long-term to maintain the original color, fragrance, taste, shape, nutritional value.

4. Sealing to adjust the heat sealing time, generally 1-3 seconds, cooling time, generally 5 seconds, vacuum time to determine the actual product and the size of the vacuum bag, the general internal vacuum machine 10-25 seconds, external vacuum switch machine 5-15 seconds. The seal must be flat and not wrinkled. The temperature of the machine should be constant.
5. When the device is put into the box, and when handling (especially for freight), it should be taken lightly to avoid damage.
