The present invention comprises a first resin layer containing a polyester resin; And a structure in which a second resin layer including a cyclo olefin copolymer (COC) is alternately laminated, and the first and second resin layers have a thickness of 0.01 μm to 0.6 μm. As the film has improved interlayer bonding force between incompatible resins, delamination does not occur even in harsh conditions, and barrier and weather resistance are excellent. Therefore, the film is useful for various packaging materials, printing materials, electronic materials, and display materials. Can be. |
