A multilayer foam film comprising a core layer and two skin layers,
- (i) the core layer comprising the product of the combination of an LDPE composition, at least one blend partner and at least one foaming agent;
- wherein the at least one blend partner comprises a polyethylene composition having a density of 0.910 to 0.940 g/cm3 and an MI from about 0.20 to about 0.50 g/10 min, and further wherein the core layer comprises from 40 to 50 percent by weight of the LDPE composition, based upon the total weight of the core layer;
- and
- (ii) the two skin layers each independently comprising the product of the combination of an ethylene 1-hexene copolymer and at least one additive;
- wherein the core layer is disposed between the two skin layers.
