ABSTRACT:
The edge of an interior lamina or laminae of a laminated sheet or film having three or more laminae is positively encapsulated to protect material enclosed by the laminated sheet or film from contacting and interacting with the edge of the interior lamina or laminae. To encapsulate the interior lamina or laminae, the edge of the laminated sheet or film is heated and the molten outer laminae are mechanically forced out and over the interior lamina or laminae to be covered, thereby positively encapsulating the edge of the interior lamina or laminae.
