All kinds of food packaging

Can be used to cook rice bags

Japan has developed a packaging bag that can be used to cook rice. There are two layers. The outer layer is a heat-resistant nylon and the inner layer is a polyethylene film. There is a water level line in the bag. Put the raw rice into In the bag, after adding water to the corresponding water line, put the bag into the pot and cook it for 20 minutes, then open the bag and eat it, which is both hygienic and convenient, especially suitable for use in the field.

Household food cooling bags

The domestic food cooling bag introduced in Japan is a double-layer polyethylene plastic bag with a length of about 20 cm and a width of 16 cm. The outer bag has a polymer water-absorbing polymer coagulant, and the inner surface has two micro-holes and a straw. . Put the bag in water for 15 to 30 minutes. The water will slowly infiltrate into the bag and form a gel-like coolant, which is then placed in the refrigerator for cooling. When traveling, people can remove food or drink from the refrigerator and put it in a cold storage bag, which is especially suitable for midsummer use.

Grain anti-mildew bag

This new kind of grain mold proofing bag was developed by Japan Mitsubishi Chemicals Co., Ltd. It is made of polyolefin resin film and contains 0.01% to 0.05% vanillin. It can slowly volatilize and infiltrate into food. It can not only inhibit mold for a long time, but also Makes food produce a fragrance.

Food preservation and preservation packaging paper

This is a kind of food packaging paper launched by Orenson Paper Co., Ltd. in Sweden. The inner and outer layers of the packaging paper have a thin layer of fluorine resin, which is waterproof and oil-proof, and has high air permeability. Wrapping food with it can make the temperature inside and outside the same, put it in the refrigerator can better maintain the original flavor of the food, so that the food is fresh.

Inflatable bags

Inflatable bags extend the food shelf life by removing food from the bag and filling it with carbon dioxide and sulphur dioxide. Potato apple beef mushrooms and other foods can be stored at room temperature for 250 days in air-filled bags. They do not need to be refrigerated during storage and transportation and can save a lot of energy, and can be reduced by 45% compared with frozen food canned foods. Energy consumption.

Self-heating or self-cooling packaging

Japan has used the exothermic reaction of calcium chloride with water or the heat released from the oxidation reaction of iron to heat the food in the package; or the endothermic reaction of calcium chloride and urea to cool the food in the package. New packaging used for canned food and travel convenience food.

Absorbent packaging

Germany STOCK-HANSE

A water-absorbing package developed by bf, made of F-VOR-PAC film, is used to package fresh fish and absorbs blood and odors to prevent contamination. It also absorbs water vapor to prevent condensed water from damaging the food in the package. Used to package frozen foods to reduce freezing time.

Anti-fog packaging

Japan's GUNZITOYOB0 and CNA have developed a polyethylene and polypropylene film with anti-fog effect that can be used as an anti-fog package for packaging fresh fruit, preventing condensation from evaporating and condensing in the film and causing fruit rot. The phenomenon occurs.

Deodorant packaging

Japan's DANICEL Chemicals has developed a deodorant that can be added to polyethylene films to package seafood foods to remove odor, and to pack food waste to remove odors such as ammonia and hydrogen sulfide.

Releasable far infrared packaging

Nippon Paper Co., Ltd. has developed a ceramic-containing film for packaging fresh meat that can extend the preservation time of meat by releasing far-infrared rays.

The Vegetable Porcelain fresh packaging launched by Trebo Packaging Company combines the use of inflatable packaging technology with advanced ceramic paper packaging technology. The vegetables are packed in a film bag with porcelain paper. The air in the bag is first removed by vacuum and then filled with inert gas. After the bags are sealed, the porcelain paper will continuously emit harmless far-infrared rays. Thus restricting the activity of bacteria in the water molecules, but also can absorb a small amount of ethylene gas, greatly prolonging the preservation time of vegetables.

Among the new types of packaging, the most favored food is edible packaging paper, which is a packaging paper made from spinach, melon, carrot, kelp, banana, apple, and other fruits and vegetables, and tofu lees and other materials, and can be used to package foods. It can also be eaten directly.

Pigs can be packaged

Poland has developed a new type of packaging made of Siris material. Its production cost is lower than traditional plastic packaging. It can be used to package foods that can withstand high temperatures of 120°C. It can be used to feed pigs when used, and it can be quickly converted to underground when it is buried. fertilizer.

Biodegradable resin packaging

Japan's successful corn starch resin packaging is based on corn as raw material and plasticized. Packages made with it can be disposed of by burning biochemical decomposition and eating insects, eliminating the "white pollution" hazard. (Liu Hua)
