Multilayered Package With Barrier Properties
US Patent:
7807270, Oct 5, 2010
Filed:
Oct 31, 2001
Appl. No.:
10/416135
Inventors:

Assignee:
Valspar Sourcing, Inc. - Minneapolis MN
International Classification:
B32B 7/08, B32B 27/34, B29D 23/00
US Classification:
4284744, 4284752, 4285428, 428 367, 428 366, 428 357, 428 3691, 215 122
Abstract:
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.

International Classification:
B29C 49/04, B29C 49/06, B29C 49/22
US Classification:
264537, 264513, 264514, 264539, 264540
Abstract:
A method of manufacturing a multilayer or a monolayer plastic container is disclosed. The container has a barrier layer manufactured from (i) a polyester resin, preferably an aromatic polyester resin such as a polyethylene terephthalate, (ii) a polyamide material, preferably an aromatic polyamide material, and (iii) an oxygen scavenging material, preferably a transition method. The present invention also provides containers having a multilayer or a monolayer body. In the preparation of the barrier layer. a preform first is prepared by an injection-molding process wherein a preblend containing a diluent polyester, polyamide material, and an oxygen scavenging material is added to a base polyester during the injection molding process. The preform then is expanded to form a container.
