Double-walled beverage cups

Iggesund Paperboard has created a cup with a double-walled construction, using one material inside the cup and another for the outer wall, which functions as both a heat shield and a brand carrier.

“For the cup’s inside, we chose Invercote coated with polyethylene (PE) and for the outside, we used Aluvision, which is Invercote extrusion coated with a thin layer of aluminium foil plus PE on top of the foil,” explains Anna Adler, who is in charge of the project for Market Communications at Iggesund Paperboard. “We wanted the metallic feature in order to achieve elegance and shine even though we only printed with one colour, vintage orange.”

The project used an ornamental pattern that framed Iggesund’s Invercote brand. The plan was to cover everything except the pattern with the orange colour and then get the pattern and product name to shine by giving them a raised embossing. The Swiss toolmaker SMR Stanztechnik AG supplied the high-precision embossing tool and Italian paper cup specialist SDG Scatolificio del Garda SpA then did the printing.

The paperboard’s printability and ability to be finished to a high level of elegance are not the only reasons why Iggesund believes in a renaissance for paperboard-based beverage cups. Competing materials, such as traditional plastic or polystyrene foam cups, create a much higher carbon footprint than a cup made of paperboard with a thin PE coating, it says.
