Abstract: A sheet (2) is made by the method of the invention, in particular for use for the punching of lids for containers, in that a PE layer (5a) and a polyester (PET) welding layer (5b) of an amorphous polyester are applied to a base sheet layer (4) of polyester (PET) by coextrusion to form the finished sheet laminate (2). This ensures that the sheet (2) is transparent throughout, just as it provides the possibility of controlled delamination by separation of the PE layer (5a) from the PET welding layer (5b) in the welding area only, when the sheet (2) is pulled off a container (1). In addition, the sheet does not curl when punched into lids prior to being applied to the containers (1).

Abstract: A laminate for use in packages comprises a base layer (3), a welding layer (1), and an adhesive layer (2) sandwiched there between. The adhesive layer (2) is a hot melt or a pressure sensitive adhesive (PSA) having a shear rate of 10-150 minutes at 40° C. in a test area of 12.5 mm×25 mm. The welding layer (1) comprises a layer of a polyethylene (PE) copolymer, and optionally an additional layer of PET, PE, such as low density polyethylene (LDPE) and/or PP. The method of making the laminate involves applying a base layer (3), an adhesive layer (2) of hot melt/PSA and subsequently a welding layer (1) in one working process to form a reclosable laminate (9). This laminate may serve as a reclosable lid and exhibits a reduced risk of cracks or so-called piping in the laminate.
