Several kinds of classification of rice food packaging bags?

Rice is our life cannot leave food at ordinary times, because it is food, many worms are also very clever often run into packaging and we rob food, and rice is particularly easy to mold. So the rice food packaging should have mouldproof, insect-resistant, safety, health, quality assurance. In previous years, the main use bag and bag, but the two bags of permeability is very poor, so rice can't get good protection. With the development of science and technology, now people are starting to use plastic bags, the many kinds of plastic food packaging bags of rice are also points: ordinary rice food packaging: this bag production process does not use fresh technology, bags of rice insect-resistant, mouldproof, preservation effect is not particularly clear, usually only have the effect of moisture proof moistureproof. However, ordinary rice food packaging has strong tensile strength, more than 5 kg packing weight can be used to this kind of packing, shelf life is about 3 months. Rice food vacuum packaging, vacuum packaging can reduce the oxygen concentration in the storage environment, prevent breathing and mold for rice breeding, prevent rice mutant, mildewy, insect pest and so on, to better maintain the quality of rice. Because of high vacuum degree, the packing material wrapped tightly rice, rice end sharp, bags are easy to be big grain prick, lead to vacuum packing. During transportation and storage in bag bag and bag, the friction between the collision and whereabouts also easy to cause the bag burst. Therefore, in order to save the rice packing in good condition, you need to use the correct storage method, in order to achieve good effect. Inflatable rice food packaging bags, inflatable packaging usually filled with carbon dioxide and nitrogen, they are colorless, tasteless, non-toxic gas, and chemical stability. Rice has the ability of adsorption of carbon dioxide, rice is in 'sleep' state, to extend the shelf life effectively; Nitrogen filling of oxygen concentration reduces the storage environment, inhibit the growth of microorganisms in the rice quality of slow changes play an important role. Most studies show that inflatable packaging can effectively maintain the quality of rice, prevent mildew in rice and moths.
need huge investment, so it is important to shop with caution.
