Cooking bag is a kind of composite plastic film bag which can be heated. It has the advantages of both canned container and boiling water resistant plastic bag, so it has a wide market. Today, we analyze the common materials and advantages of high temperature resistant cooking bags.
material
High temperature cooking bag, literally you can understand according to the word, is placed on the pot of high temperature cooking, but the cooking temperature should be controlled within 135℃, 121℃, cooking time to 30-40 is the best, so the material of high temperature cooking bag must have the characteristics of high temperature resistance.
At present, there are two common high temperature cooking bags on the market, one is transparent, the other is opaque. A layer of aluminum foil is added in the middle of the opaque bag to increase the properties of shading and retaining fragrance. The more commonly used materials are generally nylon NY composite cooking grade CPP, that is, RCPP, and nylon NY composite pure aluminum AL composite cooking grade CPP, that is, RCPP. RCPP is a cooking CPP membrane. It is better than ordinary CPP film heat resistance, can withstand 121 degrees and higher temperatures. For bags that need more than 121 degrees to sterilize, RCPPS can be used. Or pet+cpp/bopa+pe, pet+al+cpp\ny+al+cpp, = thickness according to requirements, bag style: three side sealing, middle sealing, sealed, self-sealing, etc., can withstand temperature: ≤135℃.
advantage
First, fresh-keeping and fragrance. Food in storage for a period of time will appear some bad taste, even is not good for eating, so that the food is wasted. But with high temperature cooking food packaging storage food, especially some meat food, high temperature sterilization, packaging after vacuuming, a good barrier between food and oxygen contact, so it will not easily deteriorate, in a short time to achieve sterilization requirements, as much as possible to preserve the original food color, aroma, taste, shape. Because septum oxygen, food preservation is a big advantage of high temperature cooking food packaging bags.
Two, convenient transportation. The cooking bag is light, can be stacked storage, occupy a small space, packaging food, occupy a smaller space than the metal can, can make full use of storage and transportation space, save the cost of storage and transportation. At the same time, the transportation process will inevitably encounter violence, high temperature cooking bag stronger puncture resistance, collision and extrusion is not easy to damage, so the transportation is safer.
Three, easy to use. The cooking bag can be opened easily and safely. When eating, put the food in the bag together with the boiling water to heat for 5min and then open to eat. For meat food, no additional container is needed, which is more convenient to eat.
Four, cost-effective. Compared with metal cans, the unit price of high temperature resistant cooking bag is lower, which can better save costs and form a price advantage. In addition, because of the thin cooking bag, heating bag can reach the lethal temperature of bacteria quickly, energy consumption is 30 ~ 40% less than iron cans.
Application scenario
High temperature cooking bag is also widely used, mainly used in the packaging of meat, milk, corn, soybean products, our common packaging products are braised chicken, steamed corn, rice dumplings, milk, etc., which is more common in northern China.
