Insulated Thermal Box Liners

Insulated thermal box liners are lined with reflective metalized film to keep temperatures consistent during transit while protective bubble lining cushions your items. Cold chain products are commonly used for mailing or packing perishable food, flowers, and pharmaceuticals via 1-2 day service*. Thermal box liners may be used with or without a cool pack inside.

We have recently switched to a lighter-weight brand that performs better than the old brand. You can still order the old brand in sizes 12x12x5.5" and 12x12x12". However, we suggest the lighter-weight brand to save money on postage and the product.
