ABSTRACT:
A plastic container having a multilayer label applied by in-mold labeling during the blow molding of the plastic container. The label includes a non-cellular inner layer, an intermediate cellular layer compatible with the inner layer and heat bonded to the inner layer, and an outer non-cellular plastic layer compatible with the intermediate cellular layer and heat bonded thereto. The label is positioned in a mold cavity with the outer layer in contact with the mold. When a hot plastic parison at molding temperature is expanded by fluid pressure against the walls of the mold to form a container, the non-cellular inner layer becomes bonded to the outer surface of the container by heat from the container.
