Thermal insulation liners
Provided herein are products, methods, and kits, for use in regulating the temperature of an object. The present invention relates to thermal insulating liners for regulating the temperature of perishable goods or temperature sensitive products. The thermal insulating liners generally may be dimensioned to fit within a container. The thermal insulating liners may be quickly collapsed and reconstructed to improve stackability and diminish the amount of space required to store the thermal insulating liners prior to use.
