Definitions

  • a product support member i.e. a container or a tray
  • a cavity formed therein to accomodate the product and a flange around the perimeter of the member to be lidded, and the tray and the lid are not made by the same material causing recycling problems.
  • US 4,374,800 relates to a PAT (Polyalkylene terephthalate) container including a body portion of at least 20% of crystallinity, a flange having a crystallinity lower than that of the body, adjoined to the body portion.
  • PAT Polyalkylene terephthalate
  • polyesters such as, for example polyethylene terephthalate (PET), polylactic acid (PLA), polyethylene terephthalate - glycol (PETG).
  • the containers object of the present invention can be manufactured, for example, according to a process comprising the following steps:
  • the flange has a thickness ranging from 100 ⁇ to 1000 ⁇ , preferably from 200 ⁇ to 700 ⁇ , more preferably from 300 ⁇ to 600 ⁇ .
  • the second layer is made of 97% PETG Ramapet 9921W by Indorama and 3% of nucleating agent Tna S471 by Sukano ® and has a thickness of 320 ⁇ .
  • Sample 1 is tested in order to evaluate the variability of crystallinity and is tested after flange conditioning at different temperatures for different times.
  • the crystallinity of the flange is higher than the crystallinity of the container which is 2.45%.
