Zusammenfassung:	To provide a bag which can be easily opened linearly in the direction same as the direction in which the bag has been opened and from which the contents can be more easily taken out without fail. Disposition of an aluminum foil as an inner layer brings about an excellent moistureproof effect to improve the storage stability of the contents. [MEANS FOR SOLVING PROBLEMS] The bag is characterized by comprising a layered film comprising a biaxially stretched polystyrene film comprising an amorphous polystyrene copolymer resin and having a Vicat softening temperature of 110-155 DEG C and a polyethylene film, the biaxially stretched polystyrene film being disposed on the outer side of the bag and the polyethylene film being disposed on the inner side thereof. The bag may be characterized by including an aluminum foil disposed as an inner layer. This constitution produces an excellent moistureproof effect to improve the storage stability of the contents.
