摘要：
A sealable coextruded film is made from at least one outer layer and from at least one base layer, where the outer layer is composed of a propylene terpolymer comprising from 80 to 99.5 mol % of structural units derived from propylene, from 0.2 to 15 mol % of structural units derived from ethene or from a C4-C6 1-olefin (I) and from 0.3 to 15 mol % of structural units derived from another C4-C12 1-olefin (II) different from the C4-C6 1-olefin (I), and where the propylene terpolymer has been prepared using metallocene catalysts.
