What Is The Difference Between Vacuum Packaging And Ordinary Packaging Of Rice

Vacuum packed rice has less capacity than non vacuum packed rice. According to the manufacturer of woven bags, the vacuum packaging of rice bags has a strong quality assurance ability, which can reduce the oxygen concentration in the storage package, inhibit the respiratory intensity of rice and the reproduction of mold, and prevent rice from aging, mildew and insects. The quality assurance ability of non vacuum packaging is relatively weak, and the effect of insect prevention, mold prevention and fresh-keeping of rice is worse than that of vacuum packaging bags.

According to the introduction of rice packaging bag manufacturers and woven bag manufacturers, the vacuum packaging is more beautiful, but due to the large vacuum degree, the packaging materials tightly wrap the rice, and the packaging bag is easy to be punctured by rice grains, resulting in the failure of vacuum packaging. The friction, collision and drop between bags in the circulation process are also easy to cause bag breakage. Non vacuum packaging can not be shaped, but because of the strong tensile strength of plastic woven bags, this kind of packaging is often used for rice with heavy packaging weight.

The vacuum packaging of rice can reduce the concentration of O2 in the storage package, inhibit the respiration of rice and the reproduction of mold, prevent rice from aging, mildew, and insects, and better maintain the quality of rice. At present, the vacuum degree selected for rice vacuum packaging is generally between - 0, 07~- 0 and 09 kPa. Due to the high vacuum degree, the packaging materials tightly wrap the rice, and the packaging bag is easy to be punctured by the rice grains, resulting in the failure of the vacuum packaging.

The friction, collision and drop between bags in the circulation process are also easy to cause bag breakage. Therefore, it is necessary to combine the fresh-keeping packaging of rice with the circulation environment to achieve good results. The effect of insect prevention, mold prevention and fresh-keeping of rice is worse than that of vacuum packaging bag. Generally, it can only serve as a container for grain. The tensile strength of plastic woven bags is strong, and the rice with heavy packing weight is usually packed in this way.
