Abstract
The various embodiments described herein include aluminum cups and method and materials to form aluminum cups. In one aspect, an aluminum cup includes a cup side wall including an aluminum foil layer, a first polymer layer, and a second polymer layer. The first perpendicular edge of the cup side wall can be heat-bonded to the second perpendicular edge of the cup side wall, bonding the first polymer layer to the second polymer layer.
Claims26
An aluminum cup comprising:
- a common aluminum material comprising:
- an aluminum foil layer, comprising a common foil thickness of between 80 to 180 microns;
- a first polymer layer disposed on a first surface of the aluminum foil layer;
- and
- a second polymer layer disposed on a second surface of the aluminum foil layer opposite the first surface;
- a cup side wall formed from the common aluminum material, the cup side wall comprising:
- a first perpendicular edge;
- and
- a second perpendicular edge,
- wherein the first perpendicular edge of the cup side wall is bonded to the second perpendicular edge of the cup side wall to bond the first polymer layer to the second polymer layer, to have a frustoconical shape;
- and
- a cup bottom formed from the common aluminum material, wherein the cup side wall is coupled to the cup bottom and the cup side wall and the cup bottom have the same common foil thickness.
