Ingenious food packaging (I)

in recent years, with the improvement of people's living standards, all kinds of convenient, health care, medical and flavor foods will become the development direction of the food industry. In order to adapt to the development of the market and put forward new requirements for food packaging, let's enjoy the innovative new food packaging technologies of foreign developed countries in recent years

Germany: fresh-keeping packaging is unique

in Germany, the preservation of food is very scientific and reasonable. Whether meat, fish, vegetables, melons and fruits, from the origin or processing plant to the point of sale, as long as they enter the circulation field, these foods are always running in a cold chain channel that meets the quality assurance requirements of products. Large refrigerated refrigerated trucks are responsible for the connection between production areas, processing plants and sales points. In the cold storage and fresh-keeping warehouse, all adopt the air-cooled type, and the fan adjusts the temperature under the control of the computer. The leafy vegetables can be stored for 2 ~ 5 days in this kind of cold storage. Vacuum or aerated packaging is widely used in meat packaging. In Germany, the aerated fresh-keeping packaging machine is very fast. Compared with vacuum fresh-keeping packaging, In terms of color and lustre, it is obviously superior to vacuum packaging in terms of boosting the development confidence of domestic and foreign-funded enterprises and exudates. Advanced food preservation packaging technology is extremely beneficial to the demand of the food market. Recently, there are many kinds of food preservation packaging in Germany, which are scientific and reasonable. For example, melon and fruit packaging and vegetable packaging, as long as they are tubers that are not easy to be crushed, small bags (woven with plastic wires) are used Bagged; Fragile products, such as melons and fruits, are packed in cardboard boxes with good air permeability; For meat, there are frozen, vacuum and gas containing packaging forms. In the audenburg meat processing plant, raw meat is packed in a large refrigerated vacuum bag every 500 kg, with a large plastic turnover box outside. In supermarkets and stores, cooked products are sliced and vacuum packed or inflatable packed. Leafy vegetables are generally stacked in parallel in turnover boxes, and a small amount of products are packed in boxes, but the boxed products have good air permeability and no obvious condensation. In the dortmont wholesale market, vegetables, fresh fish and meat are stored in a good cold storage environment. After the vegetables are cleaned and processed at the origin, they are stored in boxes in plastic insulated plastic boxes with ice. It is predicted that the global TPE revenue growth will reach 4.7% by 2022

Japan: unique packaging efficiency

nipponcas Copper Strip Tensile testing machine hide company of Japan launched a polyolefin stretch packaging film product for food packaging. This product, called high snewcheapweave, is a multilayer film for food. It is a multilayer film composed of some olefin resins including polyethylene, which is 30% lighter than traditional products, and is easy to incinerate. Its width is 250 ~ 500mm

TBI Walker of Japan and David Smith Packaging Company of Britain jointly produced tri wallpak corrugated board, a new packaging material with paper instead of wood. Its technical performance conforms to the American national standard ppd-b-640d and 42 national government standards in the world. This kind of packaging corrugated board has large capacity, light weight, box weight is only 25% - 30% of the weight of wooden boxes with the same volume, and high strength; Good water resistance, strong sealing and good cushioning effect; The design is beautiful and practical, flexible and diverse, saving storage space, suitable for folding and stacking, and convenient for handling; Individual specially designed cartons can be reused

a Japanese food company has recently launched an antibacterial plastic packaging container, which is widely used in food production and other fields. This antibacterial plastic packaging container is synthesized from fiber plastic and polypropylene and mixed with an antibacterial agent for food film, which can prevent the reproduction of microorganisms and bacteria, prevent the deterioration of the food contained, and greatly extend its shelf life

a Japanese plastic company recently developed a new type of fast food heat-resistant packaging plastic. In addition to good processing performance and no toxicity, the main feature of this packaging plastic is that the heat-resistant deformation temperature is above 280 ℃. The packaging material is used to contain instant noodles and rush into boiling water. Compared with boiled water from foreign manufacturers, the packaging box will not be deformed, so it can completely maintain the flavor of fast food

two Japanese companies have jointly developed a packaging bag that can be used for cooking. This bag has two layers, the outer layer is nylon with strong heat resistance, the inner layer is polyethylene film, and the bag is also printed with a water level line that discharges water according to the meter. When using, just put the rice into the bag, add water to the corresponding water level, and then put the bag into the pot to cook for 20 minutes. This kind of packaging is very suitable for field use

recently, a Japanese company successfully developed an ultra-thin pure iron foil suitable for packaging semiconductor devices. It is a pure iron film with an iron content of more than 99.9%, which is equivalent to three times the strength of hard aluminum foil and six times the strength of soft aluminum foil. It has good moisture resistance. It is easy to apply adhesives and coatings on it. This ultra-thin pure iron foil is only 20 microns thick and 1.2 meters wide. (to be continued)
