Abstract
Composite film assemblies, in-mold label formed from the composite film assemblies, and articles incorporating in-mold labels. Film assemblies according to embodiments of the invention include multi-layer or composite films that include one or more optional layers of a barrier material sandwiched between films, such as heat sealable films. The composite films can be used to form labels in standard in-mold labeling processes such that standard robotics, molds, and materials can be used. The composite film assembly can seal on itself or other similar compatible films when overlapped such that a complete overlap seam is formed without edge lift or curl. The composite film assembly can be tailored to have certain barrier properties depending on the end-use application of the molded article, such as packaging of consumable products.
