A hollow fiber membrane fluid transport device is disclosed wherein the fibers are comprised of Polytetrafluoroethylene (PTFE), and the potting materials are comprised of fluorocopolymer and or fluoroterpolymer based materials. The potting of the device utilizes a compressed chemically resistant fluorocopolymer and or fluoroterpolymer film, allows for ease of manufacture without destruction of the PTFE hollow fibers, with high packing densities, and without the processing complexity of pre-melting, extruding, or chemical crosslinking of any polymeric adhesives. Furthermore, the PTFE hollow fibers can be treated with a fluoropolymeric solvent solution before the chemically resistant film is applied to enhance the adhesion of the PTFE fiber to the film. PTFE hollow fibers, and its respective fluoro-co and terpolymers as potting films impart high packing densities, superb chemical resistance and temperature resistance without membrane contamination, or low fiber pull strength, as is sometimes observed with standard potting materials such as polyurethane and epoxy.

A heat shrink tubing, which can be readily peeled in the longitudinal direction after use (e.g., to remove the heat shrink tubing from an underlying material) is provided herein. The heat shrink tubing can be of various compositions, and generally is produced from at least one fluorinated, copolymeric resin. The tubing can exhibit desirable physical properties such as good optical clarity (e.g., translucency or transparency) and/or peelability, exhibiting one or more of complete, straight, and even peeling along a given length of tubing.

A replaceable antimicrobial system for providing a replaceable antimicrobial surface to inhibit and reduce microorganism growth on a surface. The replaceable antimicrobial system generally includes providing an antimicrobial cover, positioning the antimicrobial cover upon an object such as a handle, and securing the antimicrobial cover to the object or removably affixing the antimicrobial cover with adhesive. The securing of the antimicrobial cover is accomplished by heat shrinking the antimicrobial cover upon the object. Alternatively, the securing of the antimicrobial cover is accomplished by an adhesive backing attached to the antimicrobial cover. After a period of time of usage where the antimicrobial cover loses its effectiveness to inhibit microorganisms, the antimicrobial cover is removed and a replaced with a new antimicrobial cover.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

Provided are methods and systems for manufacturing and using heat-shrink elastomeric. An example method of manufacturing a heat-shrink elastomeric element comprises providing a thermoplastic elastomeric element having a first shape; modifying the thermoplastic elastomeric element to produce a thermoset elastomeric element having the first shape; heating the thermoset elastomeric element to a temperature of at least the glass transition temperature of the thermoset elastomeric element; adjusting the first shape of the thermoset elastomeric element to produce a second shape with at least one dimension greater than that of the first shape; and cooling the thermoset elastomeric element to a temperature below that of the glass transition temperature of the thermoset elastomeric element to produce the heat-shrink elastomeric element.

The present disclosure relates to crystallizable shrinkable films and thermoformable film(s) or sheet(s) comprising blends of polyester compositions which comprise residues of terephthalic acid, neopentyl glycol (NPG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved properties.

The present invention relates to a polymer blend and to multilayer heat shrinkable films containing at least a layer made of said polymer blend, to flexible containers made of said film, such as bags, pouches and the like, useful for packaging articles, in particular food items. The invention also relates to a process for the manufacturing of such multilayer heat shrinkable films.

A heat-shrinkable polyester film that effectively suppresses a breakage phenomenon after thermal shrinkage is provided.

The heat-shrinkable polyester film is a heat-shrinkable polyester film derived from a polyester resin composition including a crystalline polyester resin in an amount of 10% to 70% in which a main shrinkage direction is designated as TD direction, a direction orthogonally intersecting the TD direction is designated as MD direction, and the heat-shrinkable polyester film satisfies the following configurations (a) and (b): (a) when an upper yield point stress in a stress-strain curve in the MD direction is designated as E1 (MPa), and a lower yield point stress is designated as E2 (MPa), the value of E1E2 satisfies the following relational expression (1):

[00001]$\begin{array}{cc}23.5E1-E250;& \left(1\right)\end{array}$ (b) a thermal shrinkage ratio A1 (TD direction at 98 C. for 10 seconds) is 30% or more.
