PharmaNEOPET® is a medical grade copolyester produced by a continuous melt polymerisation process from terephthalic acid and ethylene glycol, followed by solid state polymerisation. The manufacturing process is adjusted to minimize the residual acetaldehyde content below 0.5 ppm. The specially designed composition of the polymer is used to improve the mechanical and barrier properties of the polymer, and this makes it ideal for a wide variety of pharmaceutical and medical applications. PharmaNEOPET® resin complies with the requirements established by the 6th edition of the European Pharmacopoeia in chapter 3.1.15, requirements mandatory for Polyethylene terephthalate containers for preparations not for parental use.
