The structure of the lunch cooler bag
As the name suggests, the lunch insulation bag is a bag with heat preservation function, which is suitable for packaging various food, fresh food, and other products. Also known as ice packs in the industry, they are often used in conjunction with phase change cold storage materials to achieve the purpose of cold/heat preservation.
The lunch insulation bag generally has a three-layer structure, which are the outer layer, the heat insulation interlayer and the inner layer. The outer layer is made of Oxford cloth or nylon cloth, which is strong and wear-resistant; the heat insulation interlayer is made of EPE pearl cotton insulation material to keep the cold and heat. This layer determines the heat preservation performance of the heat preservation bag; cleaning.
At present, thermal insulation bags are widely used in the market, and thermal insulation bag devices can be used to solve the problem of thermal insulation timeliness for short-distance cold/hot preservation of food and fresh food. The heat preservation bag is light and easy to fold, which can save space and reduce costs in transportation and storage.
