A B S T R A C T Heat shrinkable material obtained by a) thermoreversible gelation of a solution of a linear polyethylene having a weight-average molecular weight of at least 4 x 105 to form a gel material having virtually the same composition as the solution started from, and b) irradiation of said gel material with simultaneous or subsequent stretching at a stretch ratio of at least 15. Specifically claimed are articles, such as fabrics woven from fibres, and tubes or tapes, having an extremely high shrink ratio upon heating.
