Polyester, nylon, polypropylene, etc. with a thickness of 7 to 30 μ and stretched at a stretching ratio of 2 to 10 times in the vertical and horizontal directions are coated on both sides of an aluminum foil 1 with a thickness of 5 to 20 μ. Biaxially oriented synthetic resin films 2 and 3 made of the following materials are laminated with an adhesive layer 4 such as a suitable adhesive or a melt-extruded synthetic resin film, with a density of 0.910 to 0.940 and a melting point of 100 to 130.
℃, linear low-density polyethylene with a tear strength of 80 to 150 g is extruded through a T-die, and the molten linear low-density polyethylene layer 5 with a thickness of 20 to 100 μ is formed into the two-layer biaxially stretched synthetic resin film 2. , 3, which is adhesively laminated on one side of
The adhesive strength between the biaxially stretched synthetic resin films 2 and 3 and the linear low density polyethylene layer 5 is 300 to 600 g/
The aluminum foil 1 has a diameter of 25.4 mm and is used as a soft packaging material.

ることができるものである。 In the present invention, biaxially stretched synthetic resin films 2 and 3 are laminated on both sides of an aluminum foil 1, and a linear low-density polyethylene layer 5 is laminated on either surface of the biaxially stretched synthetic resin films 2 and 3. The adhesive strength between the aluminum foil 1 and the biaxially oriented synthetic resin films 2 and 3, and between the biaxially oriented synthetic resin film 3 and the linear low density polyethylene layer 5 is 300~800g/25.4mm
In particular, the linear low-density polyethylene layer 5 is laminated by extrusion lamination, so there is no intervention of an adhesive layer, and when it is torn, it can be easily torn without the cushioning effect of the adhesive layer. It has a tear strength of 30 to 45 g, making it easy to tear open and quickly remove contents such as yogurt sauce and viscous cocoa. In addition, the present invention has excellent thermal bonding strength at the thermally bonded portion when the bag is manufactured using the linear low-density polyethylene layer 5 on the inner surface, which effectively prevents the bag from breaking due to peeling of the thermally bonded portion. , aluminum foil 1
The two-layer biaxially oriented synthetic resin film 2, 3 has excellent gas barrier properties, light blocking property, moisture proofing property, and aroma retention properties. In addition, the present invention has a linear low density polyethylene layer 5 extruded and laminated to reduce the tear strength and facilitate tearing and opening. It is possible to
Moreover, since the linear low-density polyethylene layer 5 is laminated by an extrusion method, the lamination process can be simplified.
