Heat shrinkable insulated packaging

摘要

A method for preparing an insulating packaging material for a container is disclosed. A first layer of insulating material can be placed around a container, a second layer of heat-shrinkable material can be placed around the first layer and heat can be applied to heat-shrink the layer and conform the label to the contours of the container. The insulating packaging material can retain its hot and cold insulative properties after being heat-shrunk. The insulating packaging material can be used as a label.
