<p>A multi-layer construction film comprising at least one layer (A) of ethylene-vinyl alcohol copolymer and having an ethylene content of 20-60 mol%, and a melt index of eta Eg/10 min., at least one adhesive resin layer (B) of ethylene polymer and having a melt index of eta Ag/10 min. and density of not more than 0.90 g/cm<3>, and a plastic film (C) wherein the layer (B) is laminated adjacent to the plastic film (C), which satisfies the following formulas. 0.5 mu m </= a </= 20 mu m (1> 0.5 mu m </= b' </= 20 mu m (2> 1 mu m </= a + b </= 30 mu m (3> 0.08 </= eta E / eta A </= 8 (4> wherein a is the thickness of the entire layer (A), b is the thickness of the entire layer (B), and b' is the thickness of one layer of layer (B), and a method for producing same. The multi-layer construction film of the present invention has gas barrier properties, flex resistance, and resistance to boiling, and does not yellow at ultraviolet rays.</p> |
