PROBLEM TO BE SOLVED: To facilitate the laminating, to eliminate the influence to the content and to further improve the adhesive strength and low-temperature impact resistance by laminating a film of modified polypropylene and an aluminum foil on the copolymer of propylene homopolymer or copolymer of propylene andα-olefin. SOLUTION: Propylene monopolymer or copolymer of propylene andα-olefin is generated by using single site catalyst made of metallocene transition metal compound and organic aluminum compound. The monopolymer or the copolymer of the propylene andα-olefin and carboxyl group-containing ethylene unsaturated monomer are brought into contact with one another to be graft polymerized in the presence of reaction accelerator to manufacture a modified polypropylene. A method for laminating the film 1 of the modified polypropylene on an aluminum foil 2 can be conducted by an extrusion laminaitng method or a coextrusion laminating method. |
