Abstract: Composites of paper and bioriented polyester plastic film are made by passing a web of paperboard and a web of plastic film, with a layer of extruded molten polymer impregnating and bonding agent between the webs, through a nip. The process involves controlling one or more of the speed of the webs, the temperature of the molten polymer, the pressure or spacing of the rolls at the nip, and the rate of extrusion, relative to the porosity and surface characteristics of the paper web such that a portion of the molten polymer impregnates partially into and becomes part of the paper web and a substantial portion lies outwardly of the surface of the paper web and solidifies to form a new surface to which the film is bonded and which it is supported clear of the paper surface. The molten polymer may be polyethylene or an ethylene acrylic acid copolymer. These composites are useful in forming corrugated structures which may be used for baking in convection ovens.

Abstract: A cohesive coating composition (16) having differential adhesion properties is applied to window glass (12) without regard to covering adjacent trim material (14) which is to be subsequently painted. The DAC (differential adhesion composition) coating (16) is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective adhesion to glass-like surfaces, so that the coating composition (16) may be easily scraped, peeled, or otherwise lifted from the glass (12), together with any paint overlay thereon, after the painting operation of the window frame (14) is completed. When subjected to sheer forces of pulling and scraping, the cohesive properties of DAC coating (16) when considered in combination with a relatively low adhesion to glass, allows the coating (16) to be removed in long continuous strips rather than fracturing into small pieces.
