The invention relates to a blank (101) for forming a container (126). The blank (101) is provided with a substrate layer and a film layer. Part of the film layer extend beyond the substrate layer to forma an area of unsupported film (122a, 122b, 122c) such that when a container (126) is formed from the blank (101), the unsupported film area (122a,122b,122c) is arranged to wrap around and seal vertices (130,132,134,136) provided at corners of an opening of the container (126).
