HEAT-SEALING MATERIAL FOR ALUMINUM FOILS AND POLYETHYLENE TEREPHTHALATE FOILS AGAINST POLYPROPYL, POLYVINYL CHLORIDE, AND POLYSTYROL CONTAINERS

摘要

The invention relates to a heat-sealable coating system which is suitable for sealing different bottoms. Said heat-sealable coating system contains a film forming dispersion while being characterized in that a polymer type A, a polyester, or a polyester mixture is contained, a polymer type B representing a (meth)acrylate homomer or/and copolymer containing standard methacrylates and/or standard acrylates is contained, and a polymer type AB, a graft copolymer of polymer type A and polymer type B is contained, and an optional polymer type C, an olefin polymer, or an olefin copolymer is contained, and a polymer type CB, a graft polymer of polymer type C and polymer type B is contained, and an optional polymer type D and/or a polymer type D_A is contained.
