ABSTRACT:
A foldable heat-preserving bag has a bag body with an upper opening, a lid to close on the upper opening of the bag body by means of zippers sewn on the bag body and the lid. A heat-preserving layer is made up of a foam rubber portion and a tin foil portion adhered and pressed together and sewn with the bag body. And, a water-proof rubber bag is stuck with the heat-preserving layer by means of sticker fastener bands provided on the heat-preserving layer and forms a preserving space in its interior for preserving things.
