Abstract

Barrierkartonki, joka käsittää yhden kerroksen, eli ensimmäisen kerroksen (1) ja joka on tarkoitettu elintarvikkeiden pakkausmateriaaliksi ja jossa ensimmäisen kerroksen (1) pääasiallinen raaka-aine on sellu, jonka SR jauhatusluku on yli 50 ja jonka neliöpaino on yli 90 g/m². Eräs keksinnön sovellus on barrierkartonki (10), jossa on vähintään kaksi kerrosta ja jossa ensimmäisen kerroksen (1) pääasiallinen raaka-aine on sellu ja että kyseisen sellun SR jauhatusluku on yli 50, ja toisen kerroksen (2) pääasiallinen raaka-aine on sellu, hioke, CTMP massa tai puolisellu ja mainitun raaka-aineen ollessa sellu sen SR jauhatusluku on yli 35, tai edellä mainitun raaka-aine-ehdon toteutuessa 1. kerroksen (1) ja 2. kerroksen (2) sellujen SR jauhatusluvut ovat päinvastoin kuin edellä on määritelty. Eräs keksinnön sovellus on barrierkartonki, jonka ensimmäisen kerroksen (1) ja toisen kerroksen (2) pääasiallinen raaka-aine on sellu, ja että kyseisen sellun SR jauhatusluku on yli 50, ja jonka toinen kerros (2) on aallotettu, jolloin barrierkartonki (10) on aaltopahvi.
