How do waterproof cooler bags work?
The function of the cooling bag is mainly from its special inner materials. The working principle of the cooling bag is mainly to use the thermal insulation material to keep the temperature inside the bag stable. Common insulation materials include foamed plastic, bubble wrap, wood chips and so on. These materials can form a heat-insulating layer to prevent the external temperature from affecting the temperature inside the bag, so as to achieve the effect of heat preservation.
The role of waterproof comes from the outer layer of the package material. Waterproof fabric is a new type of textile fabrics, it’s composited by the polymer waterproof breathable material plus fabric composite fabric.
