| 摘要 |
A multi-layer construction film is prepared by co-extrusion coating a molten multilayered polymer which satisfies the relationship: 0.08</= eta E/ eta A</=8, which comprises 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., and at least one adhesive resin layer (B) of ethylene polymer having a melt index of eta Ag/10 min. and a density of not more than 0.9 g/cm3, onto a plastic film (C) in a manner that layer (B) is laminated adjacent to plastic film (C).
