Abstract
An insulative label is provided for a beverage container to reduce heat transfer, particularly heat transfer by conduction from a consumer's hand to the beverage container. The label comprises a dual-ply construction, with a grid pattern placed between the layered materials. Preferably, the label comprises a film base layer secured to the container, the grid pattern comprising an ink and varnish mixture printed over the film base layer, and a laminate top layer secured to the film base layer. Air is trapped in the gaps or spaces between the protrusions created by the grid pattern, and the trapped air insulates the container. The label has a very thin profile, thereby not perceptibly changing the appearance of the label or the container.
