Abstract: This invention provides a polyolefinic multilayer film which has a base layer containing polypropylene and at least one outer layer. The outer layer contains at least 50% by weight of a propylene/butylene resin composition. The propylene/butylene resin composition has a low degree of crystallinity and is modified by a surface treatment, e.g. corona treatment. The surface treatment raises the minimum heat-sealing temperature to the range of 85.degree. to 110.degree. C. and unexpectedly reduces the film's tendency to block. The resulting multilayer film is useful in packaging.

Abstract: A method for improving the formability of zinc coated steel sheet, and the product produced therefrom. The steps of the method include applying to the zinc coating an oxalic acid solution in an amount that will form a zinc oxalate film having a coating weight in a range of s about 10 mg/ft.sup.2 to about 100 mg/ft.sup.2. A lubricant is applied to the zinc oxalate film, and the lubricant is adsorbed by the zinc oxalate film to provide a lubricated zinc oxalate film that is bonded to the zinc coating. The method produces an improved zinc coated sheet product having a tightly formed lubricated coating structure resistant to galling in the die steels of a forming press. The improved zinc coated sheet product having a lubricated zinc oxalate film improves formability and reduces the coefficient of friction during the forming operations that shape the zinc coated steel sheet or strip into a finished product shape.

The abrasion-protective coating comprises a weatherable polymer such as an acrylic polymer which is transparent in thin film form and adhered to the plastic sheet as a semi-permanent coating removable by an alkaline water-based cleaning agent. The thin-film form coating provides a level of abrasion protection by preferentially abrading while protecting the underlying clear plastic window from scratching. A preferred coating comprises a water-based emulsion of an acrylic polymer such as an acrylic floor polish diluted with water and applied to the window by a dipping process.
