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%.

Abstract

L'invention porte sur un récipient en polyester transparent (1.0) qui comprend une base et des parois latérales s'étendant vers le haut et se terminant par un rebord continu qui fait saillie à partir des parois latérales. Ledit récipient multicouche comprend une couche intérieure (1.1) dans une phase amorphe et une couche extérieure comprenant un agent de nucléation dans la composition du polymère, de manière à être cristallisé dans au moins une partie du rebord.
