Manufacture of draw-redraw cans using steel sheet material film laminated or extrusion coated with a high density polyethylene graft copolymer

摘要

The use of organic solvent-based coating compositions in the preparation of plastic coated steel feedstock for use in the manufacture of retortable draw-redraw food and beverage cans is substantially reduced or eliminated by using as such can feedstock a laminated or extrusion coated steel sheet having adhered to at least one, and preferably to both, major planar surface(s) thereof a layer of an adhesive synthetic thermoplastic resin composition having a crystalline melting point of at least about 250° F. and comprising graft copolymer of high density polyethylene with an ethylenically unsaturated carboxylic acid monomer.
