What's in Cooler Bags?

The Cooler Bag is filled with a refrigerant, and the liquid in the ice bag can be rapidly cooled by the refrigerant to achieve the cooling effect.

1. Quick-cooling ice bag: The outer packaging is made of composite material, which is filled with refrigerant. When using, the inner bag is crushed by hand to generate an endothermic reaction and then a new type of cooling environmental protection bag for cooling.

2. Biological ice pack: The outer packaging is made of composite material, which contains refrigerant, and is prepared with high-tech biological materials. It is clean, non-toxic, full of certain elasticity, colloidal, and has excellent cold-keeping performance. Refrigerate before use.

3. Water injection ice pack: The outer packaging is made of composite material, and the powder refrigerant is filled with water before use, and it becomes a colloid after water injection. The usage method is the same as that of the biological ice pack.
