Patent

CA 2436826

The present invention provides compositions useful as a barrier layer in, for example, packaging products. The compositions generally comprise a blend of (i) a polyester resin, preferably an aromatic polyester resin such as polyethylene terephthalate (PET) and (ii) a polyamide material (e.g., MXD6). The blend optionally may further comprise (iii) an oxygen scavenging material. The present invention also provides containers (e.g., containers formed by expansion of preforms) having a multilayered body-forming portion including: a core layer comprising the aforementioned blend; and inner and outer layers of a formable polymer composition. The present invention also provides methods of making such containers.

La présente invention se rapporte à des compositions utiles en tant que couche barrière, notamment dans des produits d'emballage. Les compositions comprennent généralement un mélange (i) d'une résine de polyester, de préférence une résine de polyester aromatique, telle qu'un polyéthylène téréphthalate (PET), et (ii) d'une matière polyamide (par exemple un MXD6). En outre, le mélange peut éventuellement comprendre (iii) une matière désoxygénante. La présente invention traite également de contenants (tels que des contenants formés par allongement de préformes) munis d'une partie multicouche formant le corps, comprenant : une couche centrale comportant le mélange susmentionné, ainsi que des couches intérieures et extérieures d'une composition d'un polymère formable. La présente invention traite également des procédés de fabrication desdits contenants.
