Abstract
A container is provided for heating items, such as contents of the container. The container has a compartment for storing an air-activated material for heating those contents. The compartment is formed between a first web of material and a second web of material, where the first web includes a first film layer laminated to a second film layer via an adhesive layer. The second film layer includes a plurality of score lines that define plugs, such that when the first film layer or a portion thereof is peeled away from the second film layer, the plugs are separated and displaced from the second film layer to create openings in the second film layer that allow air to enter the compartment. When the air contacts the air-activated material to activate the material, an exothermic reaction takes place that serves to produce heat, such as to heat the contents of the container.
