Patent number: 7018712Abstract: Volatile organic compound or other materials are produced in the thermoplastic manufacture of thermoplastic polyester beverage containers. Such materials can be eluted into beverages such as carbonated beverages, sparkling or still water from the polyester. Such thermoplastic polyester resins can be manufactured with a material that can prevent the formation of, or react with, and absorb volatile by-products during the formation of thermoplastic preforms or containers from the thermoplastic pellet or chip. Further, as the preform is blown into a polyester container, the active materials of the invention prevent the generation of additional undesirable volatile materials. Lastly, the scavenger material can act as a barrier that prevents transport of materials from the exterior of the container into the container contents.Type: GrantFiled: March 2, 2005Date of Patent: March 28, 2006Assignee: Cellresin Technologies, LLCInventors: Willard E.

Publication number: 20050089658Abstract: The present invention describes both a stretch-blow-molded opaque polyester container and a method of making it. The container, typically a beverage bottle has less than 15% transmission of visible light (500 nm) through a 0.4 millimeter wall thickness. It contains from about 0.1 to about 5 wt. % of said opacifying material. The opacifying material may be any material compatible with polyester resin. The method of making the container includes introducing the opacifying material during polymerization, or prepared as a master batch for mixing with the polymer. Selection of certain opacifying materials can also result in favorable reheat properties, gas permeation-barrier improvements, and when the resin contains both opacifying material and oxygen scavenger there can be a synergistic effect with respect to CO2 permeation.Type: ApplicationFiled: January 31, 2003Publication date: April 28, 2005Inventors: Geoffrey Scantlebury, Zhenguo Liu, Xiaoyan Huang

Patent number: 5925710Abstract: The present invention relates to a polyester polymer composition containing graphite in the range of about 3-60 parts per million based on the polyester. The size of the graphite particles is greater than about 0.5 .mu.m. As an upper limit, however, any particle size which is not visible to the naked eye is acceptable. Such polyester polymers having graphite incorporated therein absorb infrared radiation better than polymers containing no graphite and thus in the production of plastic bottles less energy is required to heat the preform so that it can be blow molded into a bottle.Type: GrantFiled: June 9, 1997Date of Patent: July 20, 1999Assignee: Hoechst Celanese CorporationInventors: Audrey C.

Patent number: 5874517Abstract: There is disclosed a process for reducing the amount of acetaldehyde generated when polyethylene terephthalate (PET) chip is subjected to high temperatures in order to render the PET chip suitable for making food containers, particularly beverage bottles. This process comprises the addition of primary and secondary antioxidants either prior to or after the PET polycondensation reaction in order to reduce the amount of regenerated acetaldehyde produced by the polymer. The polyethylene terephthalate produced by this process reduces regenerated acetaldehyde by at least 25% in comparison to control resin produced without antioxidants, while maintaining suitable color for use as clear glass replacement. There is also disclosed a process for molding a PET preform wherein the polymer prepared as described above is melted, formed into the desired preform shape, and solidified by cooling. This preform can then be reheated above its glass transition temperature and molded into the desired container shape.Type: GrantFiled: December 23, 1997Date of Patent: February 23, 1999Assignee: Hoechst Celanese CorporationInventors: Xiaoyan Huang, Ligia Dominguez
