Abstract: Disclosed are hot-melt, curl-free methods, structures, and compositions. One embodiment provides an optionally oriented base film having a first side and a second side, wherein the optionally oriented base film base film is transparent or opaque. Further, the composition includes a water-based primer applied to the first side. Further still, the composition includes a water-based coating applied to the first side having the water-based primer disposed thereon, wherein the water-based coating has a weight of at least 0.1 g/m2, wherein the composition is curl-free and has a barrier to one or more migratory additives and components in a hot-melt adhesive on the first side.

Abstract: Disclosed are methods, compositions and structures that, in one example embodiment, is a film that includes a multilayered base film comprising a core and at least one printable coating applied to at least one outer surface of the multi-layered film. The at least one printable coating may include an acrylic-based polymer, and have a dry coating weight is within a range from 0.1 g/m2 through 0.9 g/m2 with a pH of at least 9. The film complies with European regulations for use in food-contact packaging and labeling, which are examples of applications for the disclosed films.
