A thermoplastic composition including a mixture of three particular and different polyolefins, including one of a polyamide-grafted polyolefin having particular polyamide grafts (type and quantity), for example, a polyamide-grafted polymer having a polyolefin trunk containing a residue of at least one unsaturated monomer and a plurality of polyamide grafts. Also, a thermoplastic film and, more specifically, a film for encapsulating a photovoltaic module incorporating the polyamide-grafted polyolefin composition.
