  • 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.
  • a generally known process to form a polyester tray includes extruding a polyester sheet in amorphous phase and subsequently crystallizing the whole tray by using a two stage mold, one hot for crystallization and the other cold for cooling down the article.
  • 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.

  • GB 2 205 063 relates to a PET container having different degrees of crystallization in different regions of the article to ensure best functionality, the different degree of crystallization of the tray is obtained using a special mold at different heating region without using nucleating agents.
  • US 2007/0082151 relates to a polyester container with a flange with a projecting portion, which exhibits low-temperature heat sealability.
  • object of the present invention is a clear multilayer polyester container comprising a base and upwardly extending side walls terminating in a continuous flange projecting from the side walls, said multilayer container comprising at least an inner layer of an amorphous polyester and a bulk outer layer comprising a polyester in admixture with a nucleating agent, said bulk outer layer being crystallized in at least one portion of said flange.
  • the term “inner layer” means the layer of the container that will be in contact with the content of the container or in alternative that part of the container that comes in contact with the forming plug of the mold; in Figure 1 the “inner layer” is indicated by (1.1), the crystallized portion of the flange and the bulk outer layer are indicated by (1.2) and (1.3), respectively.
  • a container according to the present invention wherein said bulk outer layer is continuosly crystallized all along the flange is particularly preferred.
  • the container is a double-layer or tri-layer container.
  • the inner layer is in the amorphous phase and the crystallized portion of the flange is in the other outer layer.
  • the inner layer is in the amorphous phase and the crystallized portion of the flange is preferably in the intermediate bulk layer.
  • the third outermost layer is preferably amorphous, being the nucleating agent preferably in the second layer.
  • the portion of the bulk outer layer of the flange is crystallized while the other parts of the same, i.e. of the side walls and of the bottom part of the container, remain in amorphous phase, i.e. with a crystallinity percentage lower than 10%.
  • the polymers used in the present invention are clear amorphous thermoplastic polymers that can be injection molded or sheet extruded.
  • polyesters such as, for example polyethylene terephthalate (PET), polylactic acid (PLA), polyethylene terephthalate - glycol (PETG).
  • the polymer used in the present invention is PET or PETG.
  • the inner layer remains amorphous during the crystallization of the flange so it can easily seal to a top lid using conventional sealing system, such as sealing bars.
  • the bulk outer layer(s) comprising the nucleating agent can be crystallized in the flange part of the container, for example by using the mold showed in Figure 2.
  • the nucleating agent used to promote crystallization is contained in the bulk outer layer of the container and preferably only the flange portion is crystallized.
  • nucleating agents which can be used in the container according to the present application and nucleating agent known in the art and commercially available, are:
  • alkali metal salts of organic acids e.g. carboxylic acid; sodium, lithium, potassium benzoates

  • sodium, lithium, potassium benzoates see D. Garcia, Heterogeneous nucleation of PET, J. of Polymer Science - Polymer physics edition, Vol 22, 2063-2072, 1984 and R. Legras, C. Bailly, M. Daumerie, V.
  • the nucleating agent preferably used in the present invention is commercially available as Tna S471 by Sukano ® .

  • the crystallization of the flange is therefore selectively guaranteed by the heating provided on the flange using, for instance, a mold similar to the mold showed in Figure 2.
  • the heating can be provided using a mold at different heating zones in order to crystallize only a portion of the flange or preferably the entire flange.
  • the percentage of crystallization in the bulk outer layer outside the flange remains lower than the percentage of crystallization of the flange or portions of the flange.
  • the crystallization of flange may take place, preferably, in a forming mold but also outside a mold.
  • the percentage of crystallization of the flange or portion of the flange is equal to or higher than about 10%, preferably higher than 12%, more preferably higher than 15%.
  • the crystallization of the flange takes place by heating the bulk outer layer generally at a temperature of from 270°C to 300°C, preferably at 275°C for a time comprised between 5 seconds and 10 seconds, preferably between 6 seconds and 8 seconds.
  • the heat transfer takes place by conduction, induction or convection systems.
