Intended use: Insulated pouch with zip-lock closure and a die cut handle is designed for transportation and temporary storage of thermolabile drug products and laboratory reagents, as well as goods and products that require different temperature modes (caviar, confectionery, drinks). It is ideal for sending by mail in the standard mail container. Design: The inner 10-mm-thick layer of multilayer air-filled polyethylene acts as the main thermal insulation and protects against convection and conduction heat (cold) flow from the environment. The top layer, laminated foil, provides additional protection from external temperature radiation.
