France develops frozen food insulation bag packaging

the appearance of insulation bag is similar to that of commodity or super market. Finally, it also saves expenses for kindergartens. The commodity plastic bag and paper bag provided by the market are similar, but if a manipulator system that can operate continuously is adopted in the material test, it is too thick. The bag is divided into two layers, the outer layer is general plastic and thick paper, and the inner layer is an insulating layer made of nylon fiber. The upper part of the commodity bag is tightly sealed, and the principle is similar to that of a thermos bottle. The holding time is 2 hours, 3 hours and 4 hours, and different temperatures such as 0 ℃, - 4 ℃ and 10 ℃ are maintained. There are also portable travel bags, which can hold more than 10 kilograms of frozen food, and the heat preservation time is longer. Frozen food insulation bags provide great convenience to consumers with stable performance, and are very beneficial to the sale of frozen or quick-frozen food in supermarkets
