<p>A process for the manufacture of an Al/plastic laminate foil is described. The laminate comprises an aluminum foil with plastic foil stuck on to at least one of its sides whereby the plastic foils exhibits an elongation at fraction of 80-100% and the adhesive joining the components achieves a shear strength of at least 0.3 N/mm2. The plastic foils bear a greater part of the applied load when the laminate foil is stressed. The laminate foil is suitable for the manufacture of containers by deep drawing whereby no cracks or macropores form in the Al foil. The laminate effectively excludes light, water vapor and aromas from external sources and prevents the loss of aroma from the contents of such containers.</p> |
