A multilayer film including a barrier layer, a sealing layer, and an alcohol barrier layer. The alcohol barrier layer includes cyclic olefin copolymer and is positioned between the barrier layer and the sealing layer. The multilayer film can be used to form a pouch for containing an alcohol-based hand sanitizer.

[Problem] 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. [Solution] 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.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

A seal for a vacuum lifter and method of manufacture wherein the seal has a continuous unbroken outer fluid resistant skin of elastomer which forms a boundary around a homogeneous cellular structure with no interior seams or joints.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

The soft boot and liner include a moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

The present invention relates to the technical field of composite materials comprising a thermosetting polymer matrix in which thermoplastic polymer and/or elastomer particles are dispersed. More precisely, the invention relates to a novel type of polymeric material obtained by using a particular ionic liquid as cross-linking agent for an epoxy resin mixed with a thermoplastic polymer and/or an elastomer. The invention also relates to a process for manufacturing said composite material and uses thereof, notably in the aeronautical, aerospace, automotive, maritime, wind power, electronics, or sports and leisure sectors.

A multilayer container including: an outermost layer (1) containing a propylene-based polymer A containing homopolypropylene as a main component having a melt flow rate in a range of 2.0 to 10.0 g/10 min; an inner layer (2) containing 50 to 99% by weight of a propylene-based polymer B containing homopolypropylene as a main component having a melt flow rate of not more than 5.0 g/10 min and an isotactic index of not less than 93%, and 1 to 50% by weight of an ethylene-α-olefin copolymer C; and a barrier layer (4) occupying 5 to 20% by weight of the whole container. The ratio (L/D) of container height (L) to diameter (D) is not less than 0.5, and a volume shrinkage based on volume measured before and after heat sterilization at 121° C. for 30 minutes is not more than 5%.

Disclosed is a molded article including a modified fibroin and a water resistance-imparting material. The modified fibroin and the water resistance-imparting material may be covalently bonded.

A performance footwear, apparel or medical accessory product for hot, cold, and all-weather conditions, the performance footwear, apparel or medical accessory product comprised of a series of material layers having: a first layer of a breathable, moisture transfer, antimicrobial inner lining, fabric or nonwoven material or a combination of fabric or nonwoven material; a second layer comprising a breathable, moisture transfer, absorbent, antimicrobial, mechanically bonded, antimicrobial, nonwoven material comprised of shaped, channeled, grooved and lobed synthetic polymer fibers, antimicrobial silver polymer fibers and natural and synthetic, thermal and cooling fibers wherein the fiber combinations naturally provide adjustable thermal regulation; and a third exterior layer comprised of a breathable, antimicrobial woven fabric, knitted fabric, spacer fabric, nonwoven material, leather material or a combination thereof.
