Abstract
A windowed paperboard carton having a window aperture extending across two or three major wall panels, which aperture is closed by a clear plastic sheet. The plastic is adhered to the carton in selected areas but not in zones of articulation where the window goes around the corner of the carton. Special elongated slots are disposed along the lines of articulation of the plastic sheet and paperboard in non-adhesive areas to eliminate deleterious stress concentrations in the composite paperboard-plastic sheet blank.
