High temperature cooking bag for non woven fabric production line
Non woven production line www.handern.comHigh temperature cooking bag is a kind of high-temperature cooking bag developed by US Navy stone Research Institute in 1960s, which is used in Zihang food It's a kind of packaging material. The sterilized food can be stored at room temperature for a long time, and it is easy to use. Therefore, after it was introduced to Japan, it has been developed rapidly in Japan, with an annual rate of 20%. Up to now, the packaging of tongpin luoyishang has developed from 500g / bag to more than 1ke so-called business hot me, and the packaging bag has developed into self-supporting bag, pallet and other types; There are 267 kinds of fast food and 100 kinds of other food packaging from curry food. There are 36 companies in Japan that produce high-temperature steamed vegetable to high-temperature Yanjiao packaging materials. The structure, materials and production process of packaging materials are also changing. Polycarbonate and other engineering plastics are also used in high-temperature steamed Yanjiao packaging materials.
High temperature cooking packaging can circulate at room temperature: it can package all kinds of food from liquid to solid The batch size is not limited: the container can be diversified, can be bag, can also be cup, plate; It is especially suitable for low salt, low sugar and children's food. In 1983, cooking food was evaluated by Japanese experts. There were 66 kinds of meat food packed in aluminum cooking bags, such as curry food, diced meat and onion, stewed food and so on twelve The processed aquatic products are packed in aluminum foil steaming bags, such as fried tuna, steamed eel, stewed herring and so on; 46 kinds of aluminum foil packaging of agricultural products, such as soup, vegetables, beans, etc; forty-seven Three kinds of seasonings, such as minced meat soup, Chinese cooking seasoning, Japanese seasoning, etc; There are 61 kinds of cooking food packed in transparent cooking bags and self-supporting bags. Therefore, cooking bag packaging is widely used in food packaging. Non woven production line www.handern.com
Due to eating habits and other reasons, high-temperature cooking bags are more suitable for China's needs, but it is difficult to develop cooking bags in Europe and the United States. Just as the Japanese view on the development prospect of high-temperature cooking bags in China, due to the fact that China has similar eating habits with Japan, the development of high-temperature cooking bags has been valued by most entrepreneurs. In Beijing Institute of food industry as the center of the research enterprise began production. Non woven production line www.handern.com
Some of the public in the United States Since 1983, some liquid drugs have been packed in steamer bags and sent to the hospital for patients to take at any time. The outer layer of the steamer bag is pet, the middle layer is aluminum box, and the inner layer is PP composite film. The package of nutrient solution is 1 l-bag with 1 kcal heat. A patient needs two bags a day. Now the cooking bag filled with medicine liquid has been put on the cardboard, and then the EVA film is used for skin packaging. There is a small piece of paper on one corner of the cardboard, which is installed on the lower side of the film, so that it can be easily opened and the medicine bag can be taken out. This type of medicine bag has been widely used in hospitals all over the United States and Europe. Non woven production line www.handern.com
General pathogenic bacteria can be killed in 30 minutes at 85'c, but botulinum spores, which can cause food deterioration and cause human death, are difficult to die. It can cause food deterioration and release toxins with high toxicity and high mortality. It can be seen that the optimal temperature for botulinum to die is 115 ~ 120c. According to the temperature of disinfection, the high-temperature cooking bag can be divided into 100c30min low-temperature distillation bag (boilmgbag); There are three types of retort bag with 120c30min and high temperature retort bag with 135'c30min sterilization. According to the transparency of high temperature cooking bag, it can be divided into transparent high temperature cooking bag and opaque high temperature cooking bag. Transparent high temperature cooking bag can be divided into non barrier and barrier. The structure of transparent non barrier cooking bag is pet12 μ M / po70um, or ony12 / po70 KOPET14~ 16pum/PO70pm，KONyl4~16pm/PO70pm。 PVDC or Eval films with high barrier properties can also be used directly, for example: Pet12 / pvdc9 / po70 or ny12 / pvdc9 / P070. The opaque cooking bags all contain aluminum boxes, and the structure is as follows: Peti2 / al9 / po70 or PA6 12 / al9 / po70. In order to give full play to the barrier property of nylon film, some manufacturers have produced transparent cooking bag with pet12 / ony12 / po70 structure, which has good barrier property. Pet prevents the moisture absorption of nylon film, which can prevent the decline of barrier property of nylon film after moisture absorption. Non woven production line www.handern.com
