Abstract: A method for thermally bonding together a cover film (3) of an ophthalmic lens package (1) and a base part (2) of the ophthalmic lens package (1), such as a contact lens package, in particular a soft contact lens package, including the steps of providing a package holder (9) supporting a base part (2) and a cover film (3) arranged thereon, the base part (2) comprising a depression (4) containing an ophthalmic lens (5) immersed in a liquid (6); mechanically pressing the cover film (3) and the base part (2) together along a bonding area (7) having a shape completely enclosing the depression (4) while applying heat to the bonding area (7), thereby thermally bonding together the cover film (3) and the base part (2) along the bonding area (7); wherein the step of providing the package holder (9) includes arranging a flexible support element (18) on an upper surface (10) of the package holder (9) to form a support area (19) corresponding in shape to and being arranged in alignment with the bonding area (7), with the flexible support element (18) having a flexibility higher than the flexibility of the base part (2).
