Title:
RESIN-COATED METAL SHEET FOR CAN LID
Document Type and Number:
WIPO Patent Application WO/2016/093219
Kind Code:
A1
Abstract:
A resin-coated metal sheet for a can lid is configured by: heat sealing a thermoplastic resin film A on a surface to be the exterior surface side of a can lid made of a metal sheet (1), the thermoplastic resin film A principally containing PBT and PET; and heat sealing a thermoplastic resin film B on a surface to be the interior surface side of the can lid, the thermoplastic resin film B principally containing PBT. In the thermoplastic resin film A, the PBT/PET composition ratio is (40/60)‒(80/20) in terms of percentage by weight, and the ratio of the Raman band intensity (I0) at 1615 ±10 cm‒1 in the horizontal plane of polarization with respect to the surface and the Raman band intensity (I90) at 1615±10 cm‒1 in the vertical plane of polarization with respect to the surface is 0.60 or higher. The thermoplastic resin film (B) has a PET content of 95% (molar) or more. The melting point resulting from the PET in the thermoplastic resin film B is 250 to 265℃ and is at least 25℃ higher than the melting point resulting from the PBT in the thermoplastic resin film A. The half-value width of the Raman band at 1730±10 cm‒1 in the horizontal plane with regard to the surface is 15-20 cm‒1.
