What type of rice packaging bags does the packaging bag processing factory mainly do
In today's internationalized 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 films, generally more than two-layer composite material packaging bags.
Due to the diversity of food, the types of food packaging bags are rich and varied, 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 of the packaging bags, it 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: stand-up bag, sealed bag, vest bag, square bottom bag, rubber strip bag, sling bag, special-shaped bag and so on.
Third, is to classify according to the form of packaging, which can be divided into: middle sealing bag, three-side sealing bag, four-side sealing bag, yin-yang bag, stand-up bag, zipper bag, nozzle bag, roll film and so on.
Fourth, is to classify according to the function of packaging bags, which can be divided into: high temperature cooking bags, high barrier bags, vacuum packaging bags and so on.
Fifth, according to the production process classification, it is often divided into: plastic packaging bags and composite packaging bags.
In our lives, foods such as rice are usually packaged in food packaging bags such as vacuum packaging. The use of vacuum packaging can reduce the oxygen concentration in the storage environment, inhibit the respiration intensity of the rice and the reproduction of mold, prevent the rice from stale, moldy, insects, etc., and better maintain the quality of the rice. Due to the high degree of vacuum, the packaging material tightly wraps the rice, and the ends of the rice are sharp, and the packaging bag is easily punctured by rice grains, resulting in the failure of vacuum packaging. The friction, collision and drop between the bags during the circulation process of the packaging bags can also easily cause the bags to be broken. Therefore, the fresh-keeping packaging of rice should be combined with the circulation environment, so as to achieve good results.
