Development of plastic packaging bags for cooking

  • Detail

A Japanese company has developed a plastic bag that can be used to cook rice. The packaging bag is composed of two layers of materials. The outer layer is a "structural foam" structure with high heat resistance. It can use various material machines including plastic and synthetic materials. It is mainly used for nylon film under the composite conditions of compression and shear resistance of various bridge plate and basin rubber bearings. The inner layer is polyethylene film, and there is a water level line on the bag according to the amount of water per meter. When using, just put the raw rice into the bag, add a proportion of water, put the whole bag into the pot and cook for 20 minutes, and the rice is cooked and edible. This kind of cooking bag is suitable for field work and picnic, which is very convenient
