Material and effect of thermal insulation bag

At present, the main material of the thermal insulation bag lining on the market is aluminum foil and pearl cotton. This material is a thermal insulation material with a relatively low thermal conductivity, which blocks the contact with the air, so that the temperature inside the bag accumulates and cannot be directly dissipated. It prolongs the time of temperature loss in the bag, and achieves the purpose of heat preservation. The main external materials are non-woven fabrics, Oxford fabrics, nylon fabrics, polyester fabrics, PP woven materials, etc.

The thermal insulation bag generally has a thermal insulation time of more than 6 hours, which is better than the traditional ordinary iron insulation box and plastic box. It is very convenient to use, clean and hygienic. The thermal insulation bag can be used to store cakes, pizza, takeaway, lunch boxes, fruits, beverages, seafood transportation, and the preservation effect is excellent.
