Articles with enhanced gas barrier and methods for making gas barrier enhanced polyesters and articles are disclosed.
摘要:
The coated multilayer structure comprising a polymeric base layer, an inorganic oxide gas barrier layer on a surface of the polymeric base layer, and a top coat on the inorganic oxide gas barrier layer, the top coat comprising a soluble compound capable of reducing the permeability of the multilayer structure to gas or vapor. A method for enhancing the gas or vapor barrier properties of a multilayer polymeric/inorganic oxide structure is also disclosed. According to one embodiment, SiOx coated polyethylene terephthalate containers are coated with a gas or vapor barrier enhancing top coat.
摘要:
A method for increasing the crystallization rate of a crystallization polyester comprises incorporating into the polyester an effective amount of a hyperfunctional nucleation agent. The hyperfunctional nucleating agent comprises a plurality of functional groups and form stable nuclei around which the polyester crystallizes. The hyperfunctional nucleating agent facilitates faster crystallization and formation of many small crystallites. Methods of making articles such as containers with polyesters are also disclosed.
摘要:
The invention provides a novel flexible, substantially gas impermeable laminate material comprising starch/polymer blends, which can be used to make dispensing tubes, e.g., for toothpaste, which material is light, resilient, and inexpensive, which can be made almost entirely from renewable materials, and which can be recycled.
摘要:
An injection molded preform for making a stretch blow molded container having an overall stretch ratio of from about 12 to about 16, wherein the overall stretch ratio is a product of a hoop stretch ratio and an axial stretch ratio, wherein the hoop stretch ratio is from about 5.6 to about 6.5, wherein the axial stretch ratio is from about 2.4 to about 2.7, and wherein the preform comprises a CG PET Copolymer having a free blow volume of from about 650 to about 800 ml measured at 100° C. and 90 psi using a 25 gram weight preform designed for a 500 ml container with a maximum diameter of 65 mm and a height of 200 mm from below the container finish and having a hoop stretch ratio of 5.5 and an axial stretch ratio of 2.6. This invention also relates to a method of making such preforms and stretch blow molded containers and methods of making the same.
摘要:
A representation of a speech signal is received and is decoded to identify a sequence of position-dependent phonetic tokens wherein each token comprises a phone and a position indicator that indicates the position of the phone within a syllable.
摘要:
A container and product system comprising a container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body and a product housed in the container, the product comprising dyes, lakes, or both.
摘要:
A forward pass through a sequence of strokes representing a handwritten equation is performed from the first stroke to the last stroke in the sequence. At each stroke, a path score is determined for a plurality of symbol-relation pairs that each represents a symbol and its spatial relation to a predecessor symbol. A symbol graph having nodes and links is constructed by backtracking through the strokes from the last stroke to the first stroke and assigning scores to the links based on the path scores for the symbol-relation pairs. The symbol graph is used to recognize a mathematical expression based in part on the scores for the links and the mathematical expression is stored.
摘要:
A packaged aqueous carbonated beverage comprising a container which replaces at least a portion of CO2 that permeates through the container or closure. The container comprises a polyester composition including a polyester suitable for packaging aqueous carbonated beverages and a carbonating agent. The aqueous carbonated beverage is disposed in the container such that the aqueous carbonated beverage has direct contact with the container and a closure seals the beverage in the container. The carbonating agent reacts with water in the carbonated beverage forming CO2 for replacing at least a portion of CO2 that permeates through the container or closure. A corresponding method of packaging an aqueous carbonated beverage is disclosed.
