PROBLEM TO BE SOLVED: To provide an easily openable packaging material which is excellent in easy opening and oil resistance and which can be suitably used not only as the packaging material for the pillow packaging bag of a fat component-containing content such as a snack confectionery, an instant Chinese noodle and the like, a three-way sealed bag and the like but also as the various easily openable packaging materials such as the lid material of a polypropylene container and the like.SOLUTION: An easily openable packaging material is composed of at least three layers such as (A) layer, (B) layer and (C) layer in this order. (A) layer is a resin composition layer for laminate and satisfied with requirements (a)-(d). (B) layer is an adhesive layer and satisfied with requirements (e)-(g). (C) layer is made of a base material consisting of at least one or more layers. Requirements (a)-(g) are shown as follows: (a) a composition contains polyethylene and polypropylene; (b) density measured based on JIS K6922-1 is 910-945 kg/m; (c) a melt mass flow rate measured based on JIS K6922-1 is 2-30 g/10 min; (d) a film thickness is 5-25 μm; (e) a film thickness is 0.01-1.0 μm; (f) a glass transition point measured based on JIS K7121 is -30-+10°C; and (g) a storage elastic modulus E' at 20°C is 1.0×10-2.5×10Pa.SELECTED DRAWING: None |
