Abstract
A die-cut lid (20) for closing a container is disclosed; the lid being formed from a flexible composite sheet material (30). The lid comprises a functional area (70) bearing human-readable and/or machine-readable data with the lid comprising one or more rigidifying indentations (50) to promote flatness of the functional area in a resting state of the lid. The one or more rigidifying indentations are selected from the group of: i) one or more encircling indentations that border the functional area; and/or ii) a planar indentation that encompasses the functional area. A lidded container (1) comprising such a die-cut lid and a method of forming a die-cut lid are also described.
