Food is the material basis on which human beings depend. Human beings cannot do without food. If you want food to be better preserved, you need to use safe and guaranteed packaging products.
The safety requirements of multigrain packaging are anti-enzyme, insect-proof and fresh-keeping. At present, food commodities are changing from large package purchases to small package sales to meet the needs of people’s daily life for convenience, safety, nutrition, and speed. This requires food commodities to change their packaging methods. In the course of the transportation and marketing of miscellaneous grains, the packaging development trend of “big change to small, heavy to light” is the development trend of packaging.
Generally there are two materials for grain packaging: 1, PA / PE. 2, seven-layer co-extruded film.
PA / PE is made of nylon composite polyethylene. Nylon is soft, wear-resistant, airtight and has good printability, while
polyethylene is a non-toxic, odorless, colorless, transparent plastic film And it is one of the most internationally recognized
materials that can directly contact food. The food pouch made of nylon and polyethylene are called vacuum bags,
which have a very good vacuum effect and are very suitable for packaging all kinds of cereals, beans, rice and other products.
Vacuum food pouch can be stored at room temperature for at least 6 months. The load-bearing range is generally 5kg.
2. Henan Baolai Packaging Co., Ltd., a domestic food pouch technology company, has developed and produced seven-layer co-extruded high-barrier vacuum packaging based on the problem of easy aging and deterioration of miscellaneous grains. They are made of environmentally friendly materials (EVOH, PA, PET , PP, PE) It is formed by multi-layer co-extrusion by physical hot-melt method at one time, without pollution, high barrier, strong function, low cost, small capacity ratio, high strength, flexible structure and so on. Compared with composite packaging materials, seven-layer co-extruded high-barrier packaging materials do not use adhesives, thus eliminating the pollution of food such as esters and benzene and ensuring food safety; seven-layer The co-extrusion vacuum degree can reach 100%, and the two-layer dry composite material is generally 90%; the seven-layer co-extrusion is composed of more than two layers of nylon, so the packaging tensile and tear strength is greatly improved, not easy to break, and durable Transport, easy storage, anti-puncture. The seven-layer co-extruded high-barrier packaging material can be used to produce hermetic grains and rice for hermetic packaging, vacuum packaging, and more user-friendly (aluminum foil) zipper bags and self-supporting bags, which are in line with market consumption needs.
vacuum food pouch remove oxygen to help prevent the deterioration of coarse grains. The principle is also relatively simple, because food spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen for survival, and vacuum packaging is to adjust the oxygen in the cell to make the microorganisms When the loss of oxygen concentration is less than 10%, the growth and reproduction speed of microorganisms decreases sharply. When the oxygen concentration is ≤5%, most microorganisms will die or fail to reproduce due to lack of oxygen. In addition to inhibiting the growth and reproduction of microorganisms, vacuum deoxygenation also has the function of preventing the oxidation of food. Because food contains a large amount of unsaturated fatty acids, it is oxidized by the action of oxygen, causing the food to taste and deteriorate. The seven-layer co-extruded high-barrier antibacterial vacuum packaging is excellent in oxygen and water resistance, and can effectively inhibit and kill most bacteria, thereby effectively inhibiting and killing most bacteria, which can greatly extend the shelf life of miscellaneous grains.

The promotion and application of high-barrier vacuum food pouch of Bao Lai cereals has solved the problem of storage of cereals that has plagued people for a long time. It is of great significance for ensuring the quality of cereals, enhancing the brand image and economic benefits of cereal companies, and achieving the large circulation of cereals at home and abroad. A new chapter has been written in the preservation of miscellaneous grains.
