Beschreibung
Zusammenfassung:	The present invention is directed to a heat shrinkable, thermoplastic film or bag which contains at least one homogeneous ethylene alpha-olefin copolymer with long chain branching. Oriented films made in accordance with the present invention exhibit improved processability as well as improved physical properties such as resistance. L'invention se rapporte à un film ou sac thermoplastique, thermorétractable, contenant au moins un copolymère alpha-oléfinique d'éthylène homogène ayant une ramification à longue chaîne. Des films orientés fabriqués selon la présente invention présentent une amélioration de leur faculté de mise en oeuvre et de leurs propriétés physiques, telles que la résistance.
