Alu Alu Foil :
OPA Film / Adhesive / 45 micron Aluminium foil / 60 micron PVC film (25 micron) AluAlu Foil is a multilayered construction designed for very hygroscopic or light sensitive pharmaceutical and generic drugs that cannot be adequately packed with barrier plastic films. The alumina layer is sandwiched between an inner heat sealable polymeric film and an outside supporting bendable film in this structure, which is made up of an optimum combination of aluminium foil and polymeric films.
