PROBLEM TO BE SOLVED: To provide an easy-to-cut pouch which allows easy formation of a linear opening at the time of opening by using a commonly used sealant resin.SOLUTION: A pouch is formed by preparing a laminate composed of at least a sealant layer and an oriented film, laminating the laminates together, on both front and back surfaces, arranging, with the oriented films outside, and heat-sealing superimposed end parts. The pouch is provided with an opening start part in which a plurality of straight-line-segment-shaped cracks are formed at both stretching-direction pouch ends of the oriented film and a large number of rows of notches are formed in an area at positions out of the seal parts of both pouch end parts. The sealant layer includes at least one layer blended with a linear low-density polyethylene having a C4 α-olefin in a side chain and expressed by C4-LLDPE and a cyclic olefin copolymer expressed by COC. |
