Provides: easy-to-tear films with excellent straight-line cutting properties, high oxygen barrier properties, and low elastic modulus, as well as multilayer films, packaging materials and containers. An easily tearable film comprising a polyamide resin composed of more than 20 parts by mass and 70 parts by mass or less of semi-aromatic polyamide resin A and less than 80 parts by mass and more than 30 parts by mass of aliphatic polyamide resin B The amide resin component, the semi-aromatic polyamide resin A is composed of a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid, and 60 mol% or more of the structural unit derived from the diamine is derived from m-xylylenediamine, 60 mol% or more of the structural units derived from dicarboxylic acids are derived from α,ω-linear aliphatic dicarboxylic acids having 4 to 10 carbon atoms, the molar concentration of phosphorus atoms in the semi-aromatic polyamide resin, and the concentration of alkali metal atoms. The total molar concentration and the total molar concentration of alkaline earth metal atoms and Mn satisfy the prescribed relationship. |
