The invention relates to a fibrous product (2, 2.1, 2.2, 2.3) for packaging, in particular food product packaging, comprising at least one first fiber layer (4.1, 4.1′, 4.1″, 4.2, 4.2′, 4.2″, 4.3″, 4.4″, 4.5″, 4.6″, 14, 16, 18), a filter material (6) for binding mineral oil substances extending at least partly through said first fiber layer (4.1, 4.1′, 4.1″, 4.2, 4.2′, 4.2″, 4.3″, 4.4″, 4.5″, 4.6″, 14, 16, 18).
Claim CLM-00001. 1. A fiber product for foodstuff packaging, comprising at least one first fiber layer, wherein the first fiber layer comprises cellulose fibers and the fiber product is card, board or paper, wherein the first fiber layer is at least partially interspersed with a filter material for binding mineral oil substances in such a manner that the fiber product has a migration value of at least less than 0.6 mg/kg., wherein said filter material is comprised of activated charcoal.
Claim CLM-00006. 6. A method for producing a fiber product, which is a foodstuff packaging product, comprising the formation of at least one first fiber layer containing a filter material, wherein the fibers of said first fiber layer are made from cellulose fibers and said fiber product is shaped into the form of a card, a board or a paper, wherein said first fiber layer is then interspersed with said filter material for binding mineral oil substances in such a manner that the fiber product with interspersed filter material has a migration value of at least less than 0.6 mg/kg. of mineral oil, wherein said filter material is comprised of activated charcoal, wherein said fiber product is made from a fiber suspension, wherein said suspension is comprised of the first fiber layer interspersed at least in part with activated charcoal.
Claim CLM-00010. 10. A method of reducing the migration of mineral oil substances from a foodstuff in a fiber based foodstuff package, wherein the migration value of the mineral oil substances from said foodstuff is about 0.6 mg/kg or less of mineral oil substances migrating from said foodstuff; comprising interspersing activated carbon filter material into a fiber product, wherein said fiber product interspersed with filter material is in the form of card, board, paper or any combination of card, board, and paper.
Claim CLM-00017. 17. A method for binding mineral oil substances in foodstuff packaging wherein the migration value of mineral oil from the foodstuff in said packaging is reduced to at least less than 0.6 mg/kg, comprising interspersing activated carbon particles, in the size range of 1 μm to 100 μm, into a cellulose fiber layer or layers wherein said cellulose fiber layer or layers with interspersed carbon particles are formed into a card or board.
