An environmentally sound alternative to foam coolers. Thermal Shield tough, most durable box liners made today.


    Foil liner is built to fight the three basic modes of heat transfer: CONDUCTIVE: By touching two opposing surfaces together, heat can move from one source to another. The denser the item the more conductive it will be; RADIANT: Metallized foil reflects up to 97% of the surface energy. The combination of 3 specific co-extruded layers stands up to the toughest challenges; CONVECTIVE: The still air trapped in our barrier-bubble makes it difficult for opposing temperatures to penetrate.


    Foil insulated box liners are used in many ways to maintain and preserve freshness and serve as a barrier. But its main use is to reflect and reduce energy consumption. Great for overnight and priority shipping. Commonly used for transporting perishable food, flowers, and cosmetics. Freeze thermal box liners prior to use to keep items cooler for longer!

    They kept my food cold. I used them to ship food. They are surprisingly durable but I wouldn’t put too much heavy items in them because they could rip.
