This disclosure provide new multilayer polyester (particularly PET) containers that have improved gas barrier properties over conventional monolayer PET containers. In particular, a 2,5-furandicarboxylate polyester (for example, poly(ethylene furan-2,5-dicarboxylate) (PEF)) barrier layer that has superior gas barrier and mechanical properties relative to PET, that is 'sandwiched' between two PET layers, has been found to achieve a significantly higher barrier against gas permeation relative to conventional monolayer PET container of the same size and shape. Associated preforms, methods, and compositions are disclosed.

This disclosure provides a process for removing acrolein or allyl alcohol from a polyester composition, the process comprising: combining a polyester composition derived from 1,3-propanediol with an amino amide or a primary amine; wherein the amino amide or the primary amine is combined in sufficient quantities to scavenge acrolein or allyl alcohol produced from degradation of the polyester composition. An analysis of reactions between anthranilamide (AAA) and acrolein demonstrates how amines or amino amides can scavenge acrolein from thermally processed poly(trimethylene terephthalate) and poly(trimethylene furan-2,5-dicarboxylate), and thermodynamic models are presented as guidance for matching targets with scavenging agent.

Disclosed are bio-based polyester fibers, particularly a PET fibers, and a method of making the same by: contacting bio-based MEG composition with a diacid composition to form a polyester composition; and spinning and/or drawing the resulting polyester composition into a fiber; wherein the bio-based MEG composition comprises: a) monoethylene glycol (MEG); and b) from about 1 ppm to about 5000 ppm of at least one C3-Cy2 1,2-diol, wherein the C3-Cj2 1, 2-diol is linear, branched, or cyclic.

This disclosure provides new methods, compositions, containers, preforms, and designs for refillable carbonated soft drink bottles having improved caustic stress cracking resistance. The method of this disclosure combine the use of PET-based co-polyester resin that incorporates a cyclic hydrocarbon diacid co-monomer and/or a cyclic hydrocarbon diol comonomer, with a bottle design incorporating a petaloid base, for unexpectedly enhanced performance.

Refillable polymer bottle and method for improved caustic stress crack resistance

This disclosure provides new methods to characterize and relate residual stress and orientation imparted to the injection molded polymeric preform with orientation and residual stress in the resulting blow molded bottle. The method developed allows one to define and map the coupled thermal stress histories of both processes to define applicable preferred mutual processing windows for both preform and bottle molding processes. Stretch blow-molding parameters are developed using the disclosed method.

This disclosure provides economical and effective methods and apparatus for repairing scratches and scuffs on refillable bottle surfaces that minimally contaminates the bottle during the refurbishing process. In one aspect, the method comprises the steps of: a) adding at least one fluid into the polymeric packaging material such as a bottle to form at least a partially filled packaging material; and b) applying at least one heat source to an exterior surface of the at least partially filled packaging material to form a repaired polymeric packaging material. Apparatus and recycling systems that incorporate this method are also disclosed.

Repair of refillable or reusable polymer-based packaging

Preforms and methods of processing 2,5-furandicarboxylic acid (FDCA) polymers, such as poly(ethylene-2,5-furandicaboxylate (PEF), to produce preforms and articles, such as containers. The present invention also includes preforms with superior processing characteristics and containers, such as PEF beverage bottles, with superior performance properties.

Furanoic polymer preforms, containers and processing

Polymers and copolymers, and systems and methods for processing the same. Advantageously, the polymers and copolymers of the present invention have undergone processing in a falling strand devolatilizer and rotary disk finisher such that a low-cost, low-energy, and high-production-rate product is produced.

This disclosure provides effective methods for expanding the processing window for poly(ethylene furanoate) (PEF) and poly(ethylene furanoate) co-polymer (PEF co-polymer) polyester preforms, such that these preforms can be beneficially used in the fabrication of bottles and containers, including bottles for carbonated soft drinks. The processing window is expanded by, for example, pre-conditioning the PEF or PEF co-polymer preform prior to stretch blow-molding by contacting the PEF or PEF co-polymer preform with water or high (&#x3e;50%) relative humidity air for a desired time period and at a temperature greater than or equal to ambient temperature, to take advantage of the unique and unexpected properties afforded the preform by water sorption at these temperatures.

This disclosure provides new heat sealable, barrier laminate packaging structures used for beverage component pouches or cartridges, including new structures and chemical compositions of the pouch made to contain the beverage base, component, or component concentrate. These structures and compositions used for heat sealable, barrier laminate packaging balance good heat sealability with improved performance for flavor scalping, oxygen permeability, and/or undesirable moisture ingress or egress, which affect the stability and useful life of the pouch or cartridge and its contents.

Surface active components may include oils, fatty acids, or other aliphatic and aromatic moieties that compromise edge wick performance. A process of manufacturing a paperboard product may include removing surface active components from fruit fiber to be included in manufacturing paper products to obtain a paper product with improved edge wicking properties.
