Abstract

L'invention concerne l'industrie des matières plastiques. Pour préparer des films de polyester, on fond un mélange intime de polyéthylène téréphtalate PET avec une quantité de polytétraméthylène téréphtalate PTMT suffisante pour accroître de plus de 10 % la résistance au déchirement du film et on extrude et transforme le mélange pour produire des films de polyester non orientés, à orientation uniaxiale ou à orientation biaxiale. Application notamment aux rubans adhésifs et aux systèmes de fermeture de récipients pour boissons.
