Brief introduction of cooler bag 2022-05-11
There is thermal cooler material in the thermal cooler bag. This material has a relatively low thermal conductivity, which hinders the contact with the air, so that the temperature in the bag can not be directly dissipated. The thermal cooler bag is made of Oxford cloth or nylon cloth, which is tough and wear-resistant. There are waterproof rubber soles and anti-skid pads, independent thermal food storage, equipped with anti-pressure system, not to be squeezed. cooler bag, also known as passive refrigerator, is a kind of bag with high heat preservation and constant temperature effect, which has the functions of cold preservation, warmth preservation and freshness preservation. Aspects to reduce heat loss. The thermal cooler bag adopts special materials, especially the inner material, the density is higher than the density, and the super-dense thermal cooler cotton is often added in the middle. The thermal cooler lunch box is developed from the thermal cooler bottle. The thermal cooler
