Abstract:
A method of forming a multi-ply composite container for consumer products with at least one region of weakened strength, comprising the steps of:advancing a continuous body ply formed of paperboard material towards a shaping mandrel; advancing a continuous liner ply having a moisture barrier layer towards the shaping mandrel; wrapping the body ply and the liner ply around the shaping mandrel and adhering the liner ply to the body ply; advancing a continuous label ply towards the shaping mandrel downstream of the adhered liner ply and body ply; wrapping the label ply around the body ply and the liner ply and adhering the label ply to the body ply and the liner ply to create a multi-ply composite tube; and circumferentially scoring the multi-ply composite tube through the label ply and into the body ply but not through the liner ply to create a region of weakened strength in the composite tube for allowing the volume of the multi-ply container to be reduced as the volume of consumer product in the container is reduced.
