A LAMINATE MADE OF A MULTILAYER POLYESTER FILM AND OF AN ALUMINIUM SHEET, METHOD FOR MANUFACTURING SAID LAMINATE, AND BEVERAGE CAN ENDS MADE FROM SAID LAMINATE

The invention relates to a laminate aluminium/multilayer biaxially oriented polyester film comprising successively: -M- an aluminum support; -C- at least one amorphous layer C comprising at least one copolyester PET- G-which the diol units include Ethylene Grycol -EG- units and CycloHexaneDiMethanol - CHDM-units; -B- at least one crystallizable layer B comprising: * at least one copolyester PET-X which the diol units include Ethylene Glycol -EG- units and which the acid units include Terephtalic Acid -TA- units and units of at least one Dicarboxylic Acid Différent From Terephtalic Acid [DADFTA units], said DADFTA units being preferably chosen in the group consisting of Isophtalic Acid -IA- units, Sebacic Acid -SA-units, Adipic Acid -AA-units, and mixtures thereof; and * possibly at least one polyester PolyEthyleneTerephtalate PET; -A- optionally at least one layer A, identical or différent from the layer B wherein i. the concentration of the CHDM units in the layer C is comprised between 18 and 34 mol %, preferably between 22 and 33 mol %; ii. the melting température of the layer B is comprised between 180 and 245°C. The invention also relates to the manufacture of this film and its applications as a aluminium/multi-layered polyester laminate for the manufacture of easy-open ends for beverage cans.
