The present invention relates to a transparent lid sheet for being punched to a transparent sheet lid to be attached to a container, specifically either a PET (polyethyleneterephtalate), a PP (polypropylene) or a PS (polystyrene) container or a container comprising either a PET, a PP or a PS surface layer, to produce a package. The invention also relates to a method for

5

manufacture of such a lid sheet as well as a package comprising such a lid sheet.

Lid sheets of various materials and compositions are known and are used as lids on containers producing packages, e.g. cups and bottles, for the

10

packaging of especially milk products, fruit juices, drinking water, salads, pâtés, etc. The lid may be made of an Al sheet, to which a layer of welding lacquer has been applied in order for it to be able to adhere to the package. This type of lid, however, is not transparent, which is a widespread wish among consumers.

WO 2013/075713 A1 discloses a transparent lid sheet comprising a transparent PET base layer coated with an additional layer on top of the base layer in the form of a polyolefin layer and a PET welding layer of amorphous polyester, which are coextruded onto the base layer, the

20

polyolefin layer being disposed between the base layer and the welding layer.

WO 2011/160627 A1 discloses a transparent lid sheet comprising a transparent PET base layer coated with an additional layer on top of the 25
