Vacuum-packed rice can effectively extend the shelf life and reduce the adverse effects of changes in the storage environment on rice. Rice can generally be stored9-12months, but changes in the weather may cause mildew in the rice, and even rice worms that are not conducive to health. Vacuum packaging can effectively block the air and extend the shelf life of rice to18months.When we buy rice in the supermarket, we often see some vacuum-packed rice. The main purpose of vacuum packaging is to extend the shelf life of rice. Generally, the shelf life of rice without vacuum packaging is9-12months, while the shelf life of vacuum-packed rice can reach18months, be sure to see the production date on the vacuum packaging when purchasingRice has certain requirements for storage conditions. As the seasons change, the humidity and ventilation in the air will be affected, which may cause mildew in the rice, and the growth of bacteria will also cause rice worms to grow in the rice. The use of vacuum packaging can effectively block the air and avoid adverse effects caused by changes in the weather. 1, The capacity of the packaging is differentCompared with non-vacuum-packed rice, vacuum-packed rice has less capacity and less floor space. 2, The ability to guarantee quality is differentVacuum packaging has a strong ability to preserve quality, which can reduce the oxygen concentration in the storage package, inhibit the respiration intensity of rice and the reproduction of mold, and prevent rice from becoming moldy and infested with insects. The quality preservation ability of non-vacuum packaging is relatively weak, and the effect of insect-proof, mildew-proof and fresh-keeping on rice is relatively worse than that of vacuum packaging bags. 3, shape and packaging are differentVacuum packaging is more beautiful, and can be packaged in a six-sided plastic appearance, but due to the high degree of vacuum, the packaging material tightly wraps the rice, and the packaging bag is easily punctured by rice grains, resulting in vacuum packaging failure. During the circulation process, the friction, collision and drop between bags can easily cause the bag to break.Non-vacuum packaging cannot be shaped, and the effect of insect-proof, mildew-proof and fresh-keeping on rice is relatively worse than that of vacuum packaging bags. Generally, it can only accommodate grain. This kind of packaging is often used for rice with heavy packaging weight.
