Today, with the internationalization of the commodity economy, food packaging and commodities have been integrated. As a means of realizing commodity value and use value, it is increasingly playing an important role in the fields of production, circulation, sales and consumption. Food packaging bags should be produced with food-grade plastic film, generally more than two layers of composite material packaging bags.Due to the diversity of food, the types of food packaging bags are rich and varied, there are many types, and the specifications are uncertain. According to different classification standards, the classification of food packaging bags is also different.First, according to the different raw materials for the production of packaging bags, they can be divided into: low-pressure polyethylene plastic bags, polyvinyl chloride plastic bags, high-pressure polyethylene plastic bags, polypropylene plastic bags, etc.Second, according to the shape of the packaging bag, it can be divided into: upright bag, sealed bag, vest bag, square bottom bag, strip bag, sling bag, special-shaped bag and so on.The third is to classify according to the form of packaging, which can be divided into: middle-sealed bag, three-side-sealed bag, four-side-sealed bag, yin-yang bag, stand-up bag, zipper bag, nozzle bag, roll film and so on.The fourth is to classify according to the function of the packaging bag, which can be divided into: high temperature cooking bag, high barrier bag, vacuum packaging bag and so on.Fifth, according to the classification of the production process, it is often divided into: plastic packaging bags and composite packaging bags.In our lives, foods such as rice are usually packaged in vacuum-packed food packaging bags. The use of vacuum packaging can reduce the oxygen concentration in the storage environment, inhibit the respiration intensity of rice and the reproduction of mold, prevent rice from stale, moldy, and infested with insects, and better maintain the quality of rice. Due to the high degree of vacuum, the packaging material tightly wraps the rice, and the two ends of the rice are sharp, and the packaging bag is easily punctured by the rice grains, resulting in the failure of the vacuum packaging. The friction, collision and drop between the bags during the distribution process of the packaging bags can also easily cause broken bags. Therefore, the fresh-keeping packaging of rice must be combined with the circulation environment, so as to achieve good results.
