Abstract
A thermal barrier liner is preferably spray coated onto the internal surface of a container. The liner is provided in embodiments including a closed cell substrate, a base layer having gas or liquid filled microcapsules, a base layer having microencapsulated solid-liquid phase change material, or combinations thereof. For the closed cell substrate embodiment, when the liner is under pressure within the container prior to the container being opened, the liner maintains a minimum thickness. When the container is opened and as pressure is released within the container, the liner expands to achieve equilibrium. The liner can be supplemented with a foaming agent to create cellular structures. Voids created by the microcapsules enhance the thermal barrier characteristics of the liner. The phase change material changes phase from a solid to a liquid state upon absorbing heat.
