Product description

Invercote Duo is made by back-to-back pasting to triple coated Invercote G. This standard version has identical printing surfaces front and back. Alternative versions are available, with e.g. front-to-back pasting to achieve special properties or appearances. An Iggesund representive would be happy to discuss further and give advice.

Invercote Duo’s printing surfaces has the ability to faithfully reproduce the most sophisticated printing images. A patented coating formula provides outstanding lightfastness, giving the end products a longer life. Due to its strength, toughness and thickness, it is especially suitable for various display purposes and different types of rigid, exclusive packs.

Invercote Duo is particularly recommended for packaging of aroma and flavour sensitive products. The pasting glue is taint and odour neutral. Invercote Duo can be extrusion coated to add the barrier functions necessary under extreme conditions, e.g. outdoor displays or foil or film laminated for added sales appeal.

Tradition with modern packaging

In time for Christmas 2009 people throughout Sweden had an opportunity to vote for their favourite Blossa vintage mulled wine. The three winners – the 2005 vintage flavoured with cloudberry and armagnac, the 2006 vintage flavoured with lingonberries and juniper berries, and the 2008 vintage flavoured with blueberries – were released as a triple-pack. The packaging was created in partnership with converters Ekmans Jönköping.
