Abstract:
A film (11) is used for a package (1) in which the packaging inner pressure increases when being heated in a microwave oven and then the inner pressure is lowered by having steam discharged outside from the inside. The film (11) is provided with: an outer layer film (21) that is molecularly aligned by biaxial stretching; an inner layer film (22) that is laminated on the outer layer film (21) and that is thermally fusible; one or more alignment relaxation parts (21a) that are formed in the outer layer film (21); and a breaking part (13) that is formed at a position where the one or more alignment relaxation parts (21a) face each other with a predetermined interval therebetween and that is broken by an increase of the packaging inner pressure caused by the microwave oven. At at least the breaking part (13), a printing layer is not present between the outer layer film (21) and the inner layer film (23).
