Abstract
This invention relates to the development of a multi-layer PC polar laminate and its cut and form process. The laminate displays increased adhesion between a PC film layer and an adjacent film layer. As a result of the increased adhesion, less adhesive may be applied between laminate layers, which positively affects PC cracking and mold cavity contamination.
