Multilayer film having excellent recoverability

A vapor deposition multilayer film comprising:

• a multilayer film comprising:
• a resin composition (A) layer containing an ethylene-vinyl alcohol copolymer (a1) with an ethylene unit content of 20 mol % or more and 60 mol % or less and an ethylene-vinyl alcohol copolymer (a2) with an ethylene unit content being more than that of the ethylene-vinyl alcohol copolymer (a1);
• a thermoplastic resin (B) layer;
• and
• an adhesive resin (C) layer;
• and
• an inorganic vapor deposition (D) layer directly in contact with an exposed surface of the resin composition (A) layer, wherein
• an outermost layer in the multilayer film includes the resin composition (A) layer;
• and
• the multilayer film is an inflation molded article and is stretched uniaxially by 3 times or more and 12 times or less;
• an average thickness of the inorganic vapor deposition (D) layer is 10 nm or more and 150 nm or less;
• a layer structure of the vapor deposition multilayer film is:
• (i) layer (B)/layer (C)/layer (A)/layer (D);
• (ii) layer (B)/layer (C)/layer (A)/layer (C)/layer (A)/layer (D);
• (iii) layer (A)/layer (C)/layer (B)/layer (C)/layer (A)/layer (D);
• or
• (iv) layer (B)/layer (C)/layer (A)/layer (C)/layer (B)/layer (C)/layer (A)/layer (D), and
• the film is stretched in the machine direction (MD) but not in the transverse direction (TD).
