A method for preparing a metal-polymer laminate packaging material, a method for preparing a metal-polymer laminated electrochemical cell package (70) and an electrochemical cell package (70) wherein adhesion of the polymer (84, 86) to the metal sheet (78) used in the packaging material and/or hydrophobicity of the metal sheet (78) are improved. In accordance with the invention, the metal sheet is subjected to a surface treatment and thereafter coated with a polymer to form a metal-polymer laminate packaging material. Exemplary surface treatments include chromate or phosphate conversion coatings (80) anodization, or chemically cleaning the metal sheet (78) with a caustic solution and/or an acidic solution. |
