The inventions relates to a method for processing polyethylene terephthalate (PET) comprising supplying PET raw material (S1), drying the PET raw material (S4) to a target moisture level, plasticizing the PET (S5), and injecting the plasticized PET (S6) into a mold. In this method, the target moisture level is between 60 ppm and 250 ppm to generate hydrolysis of PET during plasticization (S5) resulting in a controlled drop of intrinsic viscosity of the PET. According to other aspects of the invention, there is provided a method for forming a bottle and a method for packaging still beverage in this bottle.

METHOD TO MANUFACTURE THIN STRUT STENT FROM BIOABSORBABLE POLYMER

This invention discloses a process for preparation of a balloon expandable biodegradable polymer stent with thin struts (strut thickness 130 m or less, preferably 100-110 m) with high fatigue and radial strength. The invention discloses a process for the preparation of a biodegradable polymer stent which involves deforming an extruded biodegradable polymer tube axially at a first predefined temperature by applying an axial force for a first predefined time interval. The process further includes radially expanding the axially stretched tube at a second predefined temperature by pressurizing the tube with an inert gas in one or more stages, the pressure applied in each successive stage being higher than the pressure applied in a previous stage.
