Abstract
A packaging tube including a body formed from a laminate containing a metal foil and a plastic layer is provided with a strip also formed from a laminate incorporating a metal foil and a plastic film. The metal foil in the strip is thicker than the metal foil in the body laminate. The strip provides dead-fold characteristics. The strip may extend along a joint, such as a butt joint, in the tube body so that the strip covers the joint.
