<p>Multi-layered plastic structure is produced by laminating a polyester layer consisting mainly of ethylene terephthalate or butylene terephthalate unit and gas-barrier layer contg. an olefin-vinyl alcohol copolymer using an intermediate thermoplastic resin adhesive layer contg. ester and amine gps. The formation of multi-layered structure can be carried out by such methods as hotpress, sandwich- lamination, and extrusion coating. The multilayered plastic structure has balanced gas-barrier property, impact resistance, rigidity, resistance to peeling between layers, and transparency. It is useful as a material for sealing containers.</p> |
