Definitions

  • a method of decreasing acetaldehyde content in a molded article to be produced comprises introducing into a feed throat of an injection unit a PET material to be plasticized, the PET material having been dried in a pre-treatment chamber; introducing into the feed throat an un-treated agent, the un-treated agent selected from a list including:
  • PET scrap can come from either preform producing or blow-molding stages.
  • the un-treated agent 136 does not undergo any additional drying or other treatment in the pre-treatment chamber 130 .
