Abstract

L'invention concerne l'agriculture et l'horticulture. Elle a pour objet une feuille dégradable thermoplastique munie de zones de plus grande faiblesse, par exemple de fentes, de perforations, de rainures ou de zones oxydées, en vue d'une moindre tendance des feuilles partiellement dégradées à encrasser les outils et machines agricoles, la matière thermoplastique étant avantageusement un homopolymère ou copolymère du propylène, auquel cas la composition ne contient pas d'additif favorisant la dégradation. Les pellicules dégradables thermoplastiques de l'invention sont preférées comme paillis.
