20120082810 | WATER-RESISTANT COATED ARTICLES AND METHODS OF MAKING SAME - Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by dip, spray or flow coating. The methods can make coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In some methods, the aqueous solutions, dispersions, or emulsions are substantially or completely free of VOCs. | 04-05-2012 |
20100109206 | MOLDS AND METHODS FOR INJECTION MOLDING PREFORMS - This invention relates to methods and apparatus for making articles made of polyester, preferably polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of thermoplastic material with good gas-barrier characteristics. In one preferred method and apparatus, preforms are injection molded, barrier-coated immediately thereafter, and remain on a mold portion for a time to speed cooling of the completed preform. Preferably the barrier-coated articles take the form of preforms coated by at least one layer of barrier material and the containers are blow-molded therefrom. Such barrier-coated containers are preferably of the type to hold beverages such as soft drinks, beer or juice. The preferred barrier materials have a lower permeability to oxygen and carbon dioxide than PET as well as key physical properties similar to PET. The materials and methods provide that the barrier layers have good adherence to PET, even during and after the blow molding process to form containers from preforms. Preferred barrier coating materials include poly(hydroxyamino ethers). | 05-06-2010 |
20100000957 | CONTAINERS COMPRISING A CLOSED CELL FOAM LAYER - In preferred embodiments there are provided containers such as bottles comprising at least one layer made from a foamable material comprising a polymeric carrier material and microspheres which expand during heat treatment to form the foam. The articles may be mono and multilayer. The articles can be formed by various methods. | 01-07-2010 |
20090220717 | CONTAINERS HAVING CROSSLINKED BARRIER LAYERS AND METHODS FOR MAKING THE SAME - Coated articles that can include one or more coating layers, and methods of making thereof, are disclosed herein. One or more coating layers can include a UV-curable material and a crosslinking initiator. | 09-03-2009 |
20080203617 | INJECTION MOLD HAVING A WEAR RESISTANT PORTION AND A HIGH HEAT TRANSFER PORTION - Disclosed is a preferred mold design for producing plastic, injection molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold includes a combination of hardened material components and high heat transfer material components to provide a mold having good wear characteristics, for a sufficiently long useful life, and to enable rapid cooling of the injected preform, in order to reduce the cycle time of an injection and cooling cycle. In some arrangements, the hardened materials may form a portion of the preform cavity thereby slowing the rate of cooling in those areas and inducing a semi-crystalline or crystalline structure in the cooled preform. | 08-28-2008 |
