The Insulated Box Liner is an inflatable cooler/thermal box that is capable of converting from an ordinary cardboard box to a cooler box to store the most fragile goods. Commonly used in pharmaceutical or F&B industries for chemicals and food-related products, the Airliner not only can provide users maximum protection and prolong the shelf life of their product, but it is also able to reduce storage costs. It can be easily disposed of at the end of its lifespan.
