Forests
  • It’s all Metsä Group from forest to pulp mill to board mill. This is unique in the industry, and is the reason we know exactly what our boards are made of.


Fresh from the forest
Fresh fibres are pure, as they contain no unknown chemical loads, as opposed to recycled materials.

Mill
  • All our mills have ISO 22000 food safety certication, the same standard used by the food industry.
  • The finished paperboard is carefully packaged in materials designed to avoid contamination during transportation.
  • For example, to avoid any unwanted tainting and odour caused by exhaust gases, the forklifts at our mills use liquid gas or electricity.


Pure Nordic water
Metsä Board’s mills are located in Finland and Sweden – the world’s most water-rich areas. Paperboard is 8–10% water, all taken from clean surface supplies.

Unprinted board
  • The finished board must be analysed according to global legislation. For Metsä Board this means a hundred analysis methods and thousands of tests.
  • To confirm no off-flavour of board, the Robinson test is frequently used, in which a trained person tastes milk chocolate stored together with the board. Like all measuring devices, the taste buds are calibrated. Online methods have been developed but the human senses cannot be replaced fully.
  • Research has shown that paperboard prevents microbiological growth – an advantage over plastic packaging. The board absorbs the excess moisture of the packed product (e.g. an apple) and inhibits the growth of bacteria.


Taster’s choice
Metsä Board uses 120 kg of chocolate every year to test taint neutrality – with our pure boards this is considered a delicious task. In addition to taint, odour is also tested.

Printed board
  • The customer needs to make sure – in cooperation with Metsä Board – that they select a suitable grade for the desired end use.
  • The end user is responsible for the final compliance of the packaging – unprinted paperboard is only one component, even if it makes up most of the package.


Safe and sound
Before the packaging hits the store shelves, its various materials have been tested for safety several times by the material manufacturers, converters and food packagers.

Store
  • Metsä Board helps the brand owner enhance its brand image with high quality and globally consistent boards.
  • For ultimate product protection, choose strong, clean, fresh fibre paperboard for your primary and secondary packaging. Strong packaging stays in shape and protects the packed material as it makes its way across the world.


Making the brand
Metsä Board testing ensures that the paperboard can be, if needed, safely used in both cold and warm temperatures, such as Finland and the Bahamas – or was it the freezer and the oven?

Recycling
  • Metsä Board paperboard is safe to dispose of, as it contains no harmful ingredients.
  • All Metsä Board’s products are recyclable (if the right facilities are present), compostable and can be incinerated to create energy.


Staying in the loop
Without fresh fibres, the entire fibre supply would run out in about six months. Fresh fibres play a key role in keeping the fibre loop circulating.
