Abstract
Barrier films, in-mold label formed from barrier films, and containers incorporating in-mold labels with barrier properties. Films according to embodiments of the invention include multi-layer or composite films that include one or more layers of a barrier material. The films can be used to form labels in standard in-mold labeling processes such that standard robotics, molds, and materials can be used. Preferably, the film can seal on itself such that an overlap seam can be made. The film has adequate desired barrier properties, i.e. water vapor, oxygen, light, aroma, and/or flavor retention barriers depending on the application, such as packaging of consumable products.
