ABSTRACT:
Polymeric multilayer optical films, and laminate bodies that include such films, are provided with a melt zone that extends between a first and second portion of the multilayer optical film. If a shearing operation or other external influence acts on the film in the first portion that causes delamination of individual layers of the multilayer optical film, the melt zone is effective to prevent the delamination from propagating from the first portion to the second portion. The melt zone is characterized at least in part by a deformation of individual layers of the multilayer optical film. The melt zone can be positioned to extend along and proximate to some or all of a periphery of the multilayer optical film.
