Container With Liner

A method of forming a container comprising a bottom panel and a sidewall extending along the bottom panel, the method comprising:

• obtaining a blank, a liner material, and a heat seal layer;
• forming the blank into an initial construct;
• activating the heat seal layer;
• and
• applying at least a portion of the liner material to an inner surface of the initial construct so that the liner material and the initial construct form a respective liner and base layer of the container and so that the liner is releasably attached to the inner surface of the base layer by the heat seal layer, wherein the liner is separable from the base layer after heating the container.

A container for heating a food product, the container comprising

• a base layer of material and a liner releasably attached to an inner surface of the base layer, wherein the liner is separable from the base layer after heating the container;
• a bottom panel;
• and
• a sidewall comprising at least an end panel foldably connected to the bottom panel and a side panel foldably connected to the bottom panel;
• the sidewall comprising a lower portion extending along the bottom panel and an upper portion extending upwardly from the lower portion along an intermediate fold line.

In combination, a blank and a liner material for forming a container for heating a food product, the blank comprising:

• a bottom panel;
• an end panel foldably connected to the bottom panel and a side panel foldably connected to the bottom panel;
• the end panel and the side panel being for at least partially forming a sidewall comprising a lower portion extending along the bottom panel and an upper portion extending upwardly from the lower portion along an intermediate fold line when the container is formed from the blank and the liner material;
• wherein the blank is for forming a base layer of the container, the liner material is for forming a liner that is releasably attached to an inner surface of the base layer when the container is formed from the blank and the liner material, and the liner is separable from the base layer after heating of the container formed from the blank and the liner material.
