MULTILAYERED PACKAGE WITH BARRIER PROPERTIES |
摘要 |
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 material, preferably an aromatic polyester resin such as polyethylene terephthalate (PET) and (ii) a vinyl alcohol material. The blend optionally may further comprise (iii) a polyolefin material (preferably a functionalized polyolefin material, e.g., a BYNEL material); and/or (iv) a polyamide material (preferably an amorphous polyamide material, e.g., a GRIVORY material), that optionally further comprises 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. |
