Application of high temperature cooking bag

In the process of meat production and processing, there are always two cooking processes, namely high temperature and high pressure sterilization and low temperature and normal pressure sterilization. The low-temperature sterilized meat food has a low heating temperature and the fiber of the meat is not destroyed, so the taste is fresh and tender, and various nutrients are well preserved; but because it only kills pathogenic bacteria, there are still a large number of spoilage bacteria, not only has a short shelf life, And it is very easy to cause loss in the circulation field. High-temperature sterilized meat products have excessive shrinkage of meat fibers due to the high heating temperature, and the taste is not as good as low-temperature sterilized products, but because it kills all bacteria and eliminates the internal causes of corruption, it can greatly extend the shelf life. High-temperature sterilized meat products using high-barrier packaging materials not only have a longer shelf life at room temperature, but also have convenient transportation, storage, and sales, which are very suitable for the consumer needs of modern society. Therefore, vigorously developing the production of storage-resistant meat products at room temperature is an important product development direction for the meat industry. The packaging industry conforms to this development trend, does something and innovates, which can not only meet the needs of the food industry, but also win a broad market for itself. It is understood that the earliest packaging that can store meat at room temperature is canned food, which is an iron can made of tinplate, and a glass bottle is later used as the outer packaging. Both tinplate and glass bottles have high temperature cooking resistance and high barrier properties, so the shelf life of canned food can reach more than 2 years. However, because tinplate cans and glass bottles are rigid packaging containers with large volume and heavy weight, the chemical resistance of tinplate is not good, especially when it is loaded with acidic food, metal ions are easy to precipitate, which affects the flavor of the food. In the 1960s, the United States invented the aluminum-plastic composite film in order to solve the packaging of aerospace food. It is used to package meat food. It can be stored at room temperature through high temperature and high pressure sterilization. The shelf life is more than one year. The function of the aluminum-plastic composite film is similar to the canned food box, which is soft and light, hence the name soft canned food. Store meat products with a long shelf life at room temperature, such as using rigid packaging containers, or use tinplate cans and glass bottles; if using flexible packaging, almost all use aluminum-plastic composite film. The aluminum-plastic composite film is a laminated composite multilayer film, generally three layers, and the typical structure is surface layer/adhesive/aluminum foil/adhesive/heat seal layer (CPP). The packaging film has the advantages of beautiful appearance and good mechanical properties, high barrier properties, high temperature cooking performance and excellent hygiene, and it is light and soft, so it is widely used in various food packaging. But there are also some defects, such as the texture of aluminum foil is hard and brittle, and the flexibility is not good compared with plastic film. In order to prolong the shelf life of meat products, high-temperature-resistant meat products are packaged in a vacuum package. When the aluminum foil composite material is vacuumed, due to the insufficient flexibility of the aluminum foil, it is difficult to completely stick to the contents, which easily causes the air in the packaging bag to be unclean, which affects the preservation of food. Therefore, the thickness should not be too high when using aluminum foil for meat packaging. But because its barrier property depends on the thickness and processing level, when the thickness is small, a large number of pinholes are prone to appear, so the thickness of the aluminum foil should not be too thin for the packaging of storage-resistant meat products; such as aluminum foil is too thin, aluminum foil After the composite film is evacuated, many wrinkles will be formed, which will easily produce cracks and cause the loss of barrier properties. Therefore, the thickness, barrier properties, and flexibility of aluminum foil are always the three contradictions that plague the application of aluminum foil composite films. From the perspective of the market, the aluminum foil composite film packaging food is opaque so that consumers cannot see the color and shape of the contents, which is not conducive to consumers to buy. In addition, some manufacturers use the opacity of the aluminum plastic composite film to cover up the defects of the product, or even falsify , Entrap consumers. Therefore, most consumers choose completely transparent packaging

Where is the way out for the packaging industry? The development prospects of the packaging industry

In this era of information explosion, technological innovation is changing with each passing day, and new technologies in the packaging industry are constantly being produced. So what are the development prospects of the packaging industry? Let's take a look next. my country's packaging industry will present the following development trends: domestic packaging materials continue to introduce new ones. In addition to traditional paper, plastic, glass, and metal packaging, new packaging materials such as plant materials will gradually enter the market. As more and more packaging materials continue to be popularized, the types of domestic packaging materials will be more abundant in the future. With the rapid development of the domestic material industry, various special packaging materials will appear, such as new packaging materials with higher compression resistance, barrier properties, heat sealing properties, and gas barrier properties. At the same time, the speed and automation of the packaging system have increased. Speed ​​and system flexibility will become the main criteria for choosing packaging equipment in the future. The above are some of the development prospects of the packaging industry. With the continuous maturity of technology applications in the packaging industry, such as the production of automatic packaging roll film and the use of nanomaterials, these technologies have given the packaging industry infinite vitality.
