Abstract: A heat-sealable packaging sheet comprising a base sheet of paper, a heat- sealable ethylene layer, a polyamide layer, and a polymer coextrusion coating tie layer, wherein the tie layer, the polyamide layer, and the ethylene layer have been co-extrusion coated together on a second surface of the base sheet, wherein the base sheet constitutes at least 73 wt% of a total grammage of the packaging sheet, and the coextrusion coating constitutes no more than 27 wt% of a total grammage of the packaging sheet, wherein the base sheet has a grammage of 60 to 150 g/m2, and the coextrusion coating has a grammage of 5 to 32 g/m2, wherein the tie layer has a grammage of 1 to 30 g/m2, wherein the polyamide layer has a grammage of 1 to 30 g/m2, wherein the ethylene layer has a grammage of 1 to 30 g/m2, and wherein the ethylene layer essentially consists of a coextrusion coatable copolymer of ethylene and at least one acid comonomer, wherein the at least one comonomer constitutes 5 to 20 wt% of the ethylene layer.

Abstract: A method for making a sheet laminate for being pre-punched to a sheet lid for a container, comprising the steps of providing a base sheet layer, and coextrusion coating an additional sheet layer, which comprises a tie layer comprising polyolefin and a welding layer comprising polystyrene (PS), onto said base sheet layer, so that the tie layer is disposed between the base sheet layer and the welding layer.The additional layer is coextrusion coated onto the base sheet layer.A sheet lid with a similar structure may be manufactured by punching the sheet laminate.The sheet lid may be used to close a container to form a package.
