ABSTRACT Multicomponent thermoplastic resin blends useful as the adhesive layer in multilayer film structures are disclosed which have a nonisothermal crystallization half life of less than thirty seconds. Especially preferred are three component resin blends comprising a maleic anhydride grafted high density polyethylene, an unmodified linear low density polyethylene copolymer having a density between 0.905 grams/cubic centimeter and 0.93 grams/cubic centimeter, and an unmodified linear low density polyethylene copolymer having a density between 0.89 grams/cubic centimeter and 0.92 grams/cubic centimeter. The Multicomponent thermoplastic resin blends are especially useful in blown film multilayer structures and they show particularly good adhesion to polar substrates, e.g., EVOH substrates. 36,235-F
