Atria – one of the most respected food brands in Finland – was established in 1963 as brand to represent the central organisation of co-operative Finnish slaughterhouses (TLK). Atria took over usage of the brand in 1992 when the TLK organisation was dismantled. In 1994, the Atria brand, which was already highly respected, became the name of the entire group. The brand took on its current character at the beginning of the 1990s.

The products produced by Finnish company Liha ja Säilyke Oy were brought under the Forssan brand in the 1990s with the slogan, "Enter a world of flavours with Forssan!” Atria acquired Liha ja Säilyke Oy and the Forssan brand in 1999.

The Wilhelm product range was launched in 1994 under the name ‘Mestari Wilhelm’. The range included barbecue sausages, frankfurters, meatballs and mustard. In 1999, the name was shortened to Wilhelm and the selection was narrowed down to class A barbecue sausages.

The Atria Bravuuri products were developed in Finland in 2011 to meet consumers’ changing cooking needs. Bravuuri offers all of the ingredients required for a quick and easy meal in a single package.

The Atria Kulinaari family of high-quality, top-class cold cuts with high meat content was launched in Finland in 2011.
