Abstract: The present invention relates to polymeric compositions that can be used for producing packaging with dynamic cushioning, with a pleasant touch, with reduced abrasive power, in which the expanded particles constituting the packaging adhere well to one another and do not come detached during use. Said compositions comprise: a) from 70% to 90% by weight of a vinyl aromatic polymer and/or copolymer, calculated with respect to (a)+(b); b) from 10% to 30% by weight of an ethylene-vinyl acetate copolymer (EVA) containing a percentage that ranges from 10% to 30% by weight of vinyl acetate, calculated with respect to (a)+(b); c) from 3 to 10 parts by weight of a blowing agent, calculated on 100 parts of component a) added to component b); said copolymer (b) being distributed in the polymer (a) in the form of particles having an average volumetric diameter ranging from 1 nm to 2000 nm. The compositions described and claimed do not include styrene-butadiene or styrene-isoprene block copolymers, hydrogenated or non-hydrogenated; thermoplastic polyurethanes, polystyrene-butadiene grafted polymers or styrene core-shell polymers.
