ABSTRACT:
A poly-.epsilon.-caprolactone film whose weight-average molecular mass is equal to at least 75,000 g/mol having a modulus in tension of at least 600 MPa in the transverse and longitudinal direction and a shrinkage not exceeding 1% in both directions below the poly-.epsilon.-caprolactone melting zone. The process for producing the poly-.epsilon.-caprolactone film comprises online extrusion of the poly-.epsilon.-caprolactone through a die having a temperature not exceeding 160.degree. C. immediately following its polymerization using aluminum trialkoxide as initiator. The films according to the invention are suitable for producing films for packaging, for the protection of produce or for diapers.
