Patent number: 5149389Abstract: A laminated metal sheet, the metal sheet having adhered on at least one major surface thereof a film of a non-crystalline polyester, and a process for the preparation thereof. The laminated metal sheet is particularly useful for forming into drawn and wall ironed (DWI) cans. The laminate is also useful for forming other non-retorted packaging components.Type: GrantFiled: April 18, 1990Date of Patent: September 22, 1992Assignee: CMB Foodcan plcInventors: Peter J. Heyes, Nicholas J. Middleton, Alison M. Brown

Patent number: 5100708Abstract: A laminated metal sheet, the metal sheet having adhered on at least one of its major surfaces a composite film comprising:(A1) an inner layer of a thermoplastic polymer incorporating a white pigment and a toner for compensating for the natural color of the metal sheet, and(B1) an outer layer of a thermoplastic polymer incorporating a white pigment, the concentration of white pigment in layer (B1) being lower than the concentration of white pigment in layer (A1).The laminated metal sheet of the invention is useful for forming into containers or various components thereof.Type: GrantFiled: May 28, 1991Date of Patent: March 31, 1992Assignee: CMB Foodcan plcInventors: Peter J. Heyes, Nicholas J. Middleton

Patent number: 5059460Abstract: A process for producing by simultaneous lamination a polymer/metal/polymer laminate, which process comprises(i) simultaneously laminating to each of the major surfaces of a metal sheet a composite polyester film (A) comprising an inner layer (A1) of a substantially non-crystalline linear polyester having a softening point (Ts-A1) below 200.degree. C. and a melting point (Tm-A1) above 150.degree. C. and below 250.degree. C. and an outer layer (A2) of a biaxially oriented linear polyester having a crystallinity greater than 30% and having a melting point (Tm-A2) above 250.degree. C., the metal sheet having been heated to a temperature T.sub.Type: GrantFiled: June 9, 1989Date of Patent: October 22, 1991Assignee: CMB Foodcan plcInventors: Peter J. Heyes, Nicholas J. Middleton

Patent number: 4957820Abstract: A process for producing by simultaneous lamination a polymer/metal/polymer laminate, which process comprises laminating to one of the major surfaces of a metal sheet a composite polyester film (A) comprising an inner layer (A1) of a substantially non-crystalline linear polyester having a softening point below 150.degree. C. and a melting point above 150.degree. C. but below 240.degree. C. and an outer layer (A2) of a linear polyester having a melting point above 220.degree. C., and simultaneously laminating to the other major surface of the metal sheet a polyolefin-containing film (B) comprising a bonding resin which is an acid modified polyolefin-resin containing carboxyl or anhydride groups, the metal sheet having been heated to a temperature T.sub.1 sufficient to cause softening of the polymer films and intimate contact with the metal sheet, the temperature T.sub.Type: GrantFiled: June 9, 1989Date of Patent: September 18, 1990Assignee: CMB Foodcan plcInventors: Peter J. Heyes, Nicholas J. Middleton

Patent number: 4917260Abstract: A metal can end with a one-piece tear-open closure of a polymeric material (e.g. a polyolefin or polyamide) moulded thereon so as to fill an aperture therein and to form a rim surrounding the aperture on the underside and a pull tab lying against the upper side of the can end, wherein the underside of the can end has a coating of a polymeric material bonded to the polymeric material of the rim and the upper side has a coating whose outer surface is of a different polymeric material which will not bond to the polymeric material of the closure, the materials of the coatings being chosen to be capable of being laminated simultaneously to the metal of the can end, e.g. by the use of bonding resins such as an acid-modified polyolefin resin.Type: GrantFiled: June 9, 1989Date of Patent: April 17, 1990Assignee: CMB Packaging (UK) LimitedInventors: Peter J. Heyes, Nicholas J. Middleton

Patent number: 4715913Abstract: A method for decorating substrate materials such as flat metal sheet or cylindrical metal containers in which a linear polyester/adhesive laminate film is applied to the substrate either prior to or simultaneously with a flexible dye transfer carrier. Thus, on heating the laminate film bonds to the substrate and dye is transferred from the carrier to the film. After cooling the carrier is removed, leaving a high gloss, finely decorated laminate film/substrate.Type: GrantFiled: April 24, 1986Date of Patent: December 29, 1987Assignee: Metal Box p.l.c.Inventor: Nicholas J.
