Product description

Invercote Albato is designed for luxury packaging applications where an exceptional aesthetic result is desired.The reverse side has improved printing potential compared with an uncoated surface.

Invercote Albato is a solid bleached board of medium density. The printing side is triple coated and finished to a high gloss level. The reverse side is single coated and finished to a matt level. Because of the solid bleached primary fibre composition Invercote has a superior strength and toughness compared to board grades containing mechanical or recycled fibres or single-ply bleached primary fibre board. This gives several advantages in designing and processing cartons, in packaging operations and in the use of the package itself.

Invercote Albato has an excellent surface smoothness with the ability to faithfully reproduce the most sophisticated printed images; this combined with its excellent structural, design and embossing characteristics make it ideal for the packaging of luxury products.
