Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laminated film that is used for a package suitable for use in automation such as automatic filling and packaging, and also to provide a package that normally maintains a sealed condition but allows repetition of the automatic decrease of pressure in the package when pressure in the package is increased, and that easily decreases pressure in the package and maintains the decreased pressure. SOLUTION: The laminated film is formed by bonding together two film sheets 1 and 2, each of which is formed of one or more layers. The bonded faces of the two film sheets 1 and 2 are formed of synthetic resin layers that cannot be fused by heat. These film sheets 1 and 2 are bonded by an adhesive 4 except for one portion. Through-holes 5 are made in the one film sheet 2 in a portion 3 where it is not joined to the other film sheet 1. Embossed portions 6 are formed on one of the two film sheets and along the edges of the through-holes or near the through-holes. The package is formed using the laminated film.
