Barrier boards
For better protection against moisture and grease
Metsä Board’s barrier boards respond to the growing requirements of the sustainable food service market by providing product safety, purity and protection. Our barrier boards have been developed for various food service uses as well as for other packaging applications requiring a barrier resistance against grease or moisture.
Our food service boards are made of pure and renewable fresh fibres making them a preferred choice to cups, plates and other takeaway packaging as well as for frozen food packaging.
Metsä Board’s product portfolio includes both PE extrusion coated paperboards as well as an eco-barrier board that comes with a special bio-based barrier treatment.
PE extrusion coating
PE extrusion coating creates a protective layer on paperboard to protect the packed product. Coating is applied at the extrusion line onto reverse (1PE) or both sides (2PE) of the paperboard. Single coated 1PE is used for hot cups, plates and various food service packaging that require barrier against liquid. Double coated 2PE is often used for cold cups, ice cream and frozen food packaging to achieve barrier against liquid and moisture.
Compostable and non-plastic eco-barrier paperboard with grease barrier
The recently launched eco-barrier paperboard with grease resistance is an ideal packaging solution for food, takeaway and food on-the-go applications. The non-plastic special barrier treatment made of bio-based materials and natural minerals improves the grease resistance of the board and makes it an ecological and efficient packaging material. The grease resistance can be cost-efficiently enhanced further at the converting stage with the addition of just one varnish layer.
The product is safe for direct food contact and no optical brighteners (OBA free) or fluorochemicals have been used. The biodegradable board can be recycled with paper and board recycling schemes and it has an industrial compostability certification complying with DIN EN 13432 and ASTM D6400 standards.
