A flexible and foldable foam plastic sheet and a process for making same, said process comprising initially compressing the foam sheet between two surfaces at least one of which is a textured surface (e.g., screen like) to reduce the sheet in thickness and reduce or destroy the resilience of the foam, and then, when further reduction in thickness of the resulting sheet is desired, pressing the resulting compressed sheet between two substantially smooth surfaces to achieve such desired further reduction in thickness. Mechanical properties of the foam sheet so processed are desirably increased thereby producing a foam sheet product suitable as a replacement for paper in many applications.
