| abstract |
The present invention relates to a first polymer comprising units derived from (meth)acrylate and/or (meth)acrylic acid and/or salts thereof, and a) (meth)acrylate and/or (meth)acrylic acid and/or its salts. wherein the first and/or second side of the paper component is at least partially coated with a heat-sealable coating comprising a salt and b) a second polymer different from the first polymer comprising units derived from an alkene; a paper component having a first side and a second side, wherein the first polymer and the second polymer present in the heat-sealable coating in a total amount of at least 50% by weight, based on the total weight of the coating, are from 90:10 to and present in the heat-sealable coating in a weight ratio of 35:65. The present invention also relates to a laminate obtained by heat-sealing a paper article according to the invention to a substrate comprising a paper component, a substrate and a heat-sealing layer present between the paper component and the substrate. The present invention also relates to the use of a coating for heat-sealing a paper component to a substrate. |
