Abstract (en)
[origin: WO2021185757A1] The invention relates to a method for producing an EBM bottle with 0.90 to 1.5 dl/g from a bottle-grade PET post-consumer recycling flake, i.e. a recycled post-consumer PET with a viscosity of 0.65 to 0.84 dl/g, using extrusion processes, solid state polycondensation processes and a blowing process.
