Abstract: An oriented heat-treated principal film capable of thermally-induced self-forming, including one or more (co)polymers and exhibiting a relaxation temperature (Tr), the oriented heat-treated principal film having opposed first and second major faces, a land portion on the second major face and one or more modification zones on the second major face. A cross-linked (co)polymeric carrier layer is in contact with the first major face. Each modification zone includes a central closed portion and a rim portion surrounding the central closed portion and being surrounded by a land portion. An average thickness of each rim portion is greater than an average thickness of the land portion surrounding the central closed portion. An average thickness of each central closed portion is less than the average thickness of the land portion surrounding the central portion. Methods for making such films and adhesive articles comprising such films are also disclosed.
