Metsä makes improvements to folding boxboards to guarantee off-flavour value

- Metsä Board can now guarantee a new off-flavour value for all its folding boxboards of <1 for 12 months for products stored in the original packaging, following improvements to Simcote, Avanta Prima and Carta Elega grades

 

- “Off-flavour” means a taint that may be transferred to food from its packaging

 

Metsä Board can now guarantee a new off-flavour value for all its folding boxboards, following improvements to Simcote, Avanta Prima and Carta Elega.

 

According to the standard EN1230-2, comparable to the Robinson test, the new value is: <1 for 12 months for products stored in the original package. “Off-flavour” means a taint that may be transferred to food from its packaging.

 

Metsä Board carried out substantial measures to research and improve the organoleptic properties of its folding boxboards. Metsä Board attributes the quality enhancement of its boards to: increased use of BCTMP pulp in the middle layer; technical development and new process chemistry to improve middle layer washing; fiber know-how applied to the pulping process; and more consistent board making, as production has concentrated on a small portfolio of high-quality grades, leading to more stable and standardised processes.

 

Verification of the improved quality included regular sensory testing and long-period off-flavour surveys.

 

Metsä Board’s folding boxboard grades are manufactured from fresh forest fibers. They are manufactured in compliance with good manufacturing practice and management systems certified according to ISO 9001, ISO 14001 and ISO 22000.

 

All chemicals and additives are approved according to German recommendation XXXVI of BfR and USA regulations of FDA, 21 CFR, parts 170-189.

 

Metsä Board’s Carta Integra and Carta Solida grades already meet the new off-flavour value.

 

Markku Romano, vice president of cartonboard sales in the EMEA region for Metsä Board, said: ‘Consumer demand for improved food quality, combined with market requirements for longer shelf-life, has set higher standards for packaging.

 

‘These drivers, together with tightening regulations, led us to review the sensory properties of our grades so that they continue to meet or exceed new standards.’
