The inner wall is made in the form of a supple multi-layer bag, comprising an inner layer made from a material selected from zinc or sodium ionomer resins, terionomer resins or PET copolymers in which the ionomer nuclei are located between the chains, or low-density polyethylene, an intermediate metal layer and an outer layer selected from high-density polyethylene, PET, polypropylene or polyethylene. The intermediate metal layer can be of aluminium, tin or gold with a thickness of 8-15 microns, with the inner and outer layers attached to it by the action of heat or adhesive. The metal layer can also be in the form of a metallised surface on the outer or inner layer. The outer wall of the container is made from a plastic reinforced with glass fibres.</p> |
