A blow-molded bottle for a carbonated beverage includes a threaded mouth, a cylindrical side wall, a bottom, and a standard fill capacity of 37.5 mL to 105 mL. The bottle is blow-molded from a laminated preform including an outer layer formed from polyethylene terephthalate, an intermediate gas barrier layer formed from a polyamide comprising a dicarboxylic acid component and a diamine component comprising m-xylylenediamine, and an inner layer comprising polyethylene terephthalate. The laminated preform may weigh from about 4 to 16 grams. The polyamide layer provides the bottle with excellent resistance to carbon dioxide, hydrogen, and nitrogen transmission and prevents the degradation of nutrients and flavors.

A method of manufacturing a fluid-filled chamber with a tensile element includes manufacturing a tensile element and incorporating the tensile element into a chamber. A first material layer, a second material layer, and a spacing structure having a plurality of support portions and a plurality of gaps may be stacked. The material layers may be located on either side of the spacing structure or on one side of the spacing structure. A strand may be stitched through the gaps to join the material layers and to form the tensile element. The spacing structure may be removed, and the first material layer may be spaced from the second material layer such that segments of the strand extend between the material layers. The tensile element may then be secured to opposite interior surfaces of an outer barrier, and the outer barrier may be pressurized to place the strand in tension.

Ultraviolet-C (UV-C) radiation shielding films including a substrate made of a fluoropolymer, a multilayer optical film disposed on a major surface of the substrate, and a heat-sealable encapsulant layer disposed on a major surface of the multilayer optical film opposite the substrate. The multilayer optical film is made of at least a multiplicity of alternating first and second optical layers collectively reflecting at an incident light angle of at least one of 0°, 30°, 45°, 60°, or 75°, at least 30 percent of incident ultraviolet light over at least a 30-nanometer wavelength reflection bandwidth in a wavelength range from at least 100 nanometers to 280 nanometers. The ultraviolet light shielding film may be applied to a major surface of a photovoltaic device, such as a component of a satellite or an unmanned aerial vehicle. Methods of making the UV-C radiation-protective films also are disclosed.

A tube for receiving a liquid or pasty product comprising a multilayered tube jacket, the tube jacket having one or more outer layer(s) made of polyolefin, one or more inner layer(s) made of polyolefin and a barrier layer arranged between the outer layer(s) and the inner layer(s), wherein the barrier layer consists of an ethylene-vinyl alcohol copolymer (EVOH), and wherein the ethylene-vinyl alcohol copolymer of the barrier layer has an ethylene content of <35 mol % and the thickness of the barrier layer is ≤25 μm.

Recyclable films and methods of making the recyclable films are provided. The recyclable films include a low melt index blend of super hexene LLDPE and bimodal HDPE and an anti-stick additive having a melting point of at least about 115° C. The recyclable films have a heat resistant coating on the film surface that prevents the film from softening and sticking to heat seal jaws during the production process. The recyclable films also have improved tear strength and melt strength such that instances of tears or break offs during the machine direction orientation portion of the production process are significantly reduced or eliminated.

A multilayer thermoplastic article blended with hydrolytically unstable polymers and a material component for improved recyclability. The multilayer thermoplastic article having an inner layer being made of a thermoplastic material, an outer layer being made of a thermoplastic material, and an intermediate layer disposed between the inner layer and the outer layer. The intermediate layer is made of a blended material comprising 50 to 99 wt. % of a hydrolytically unstable polymer and 1 to 50 wt. % of the material component selected from the group consisting of an oxygen scavenger, an oxidizable organic polymer, a passive barrier material, Iron, Ascorbic Acid, and potassium sulfite.

The present invention provides coated films and packages formed from such films. In one aspect, a partially coated film comprises (a) a film having two outer surfaces, wherein a first outer surface is provided by a film layer that comprises from 70 to 100 percent by weight of a polyolefin having a density of 0.860 to 0.965 g/cm.sup.3; and (b) a coating on the first outer surface of the film comprising polyurethane, wherein the coating covers less than 25% of the surface area of the first outer surface of the film and wherein the coated portion of the film exhibits an Elmendorf tear in at least one of the machine direction or cross direction that is at least 20% less than the Elmendorf tear of the uncoated portion in the same direction, with the Elmendorf tear being measured in accordance with ASTM D1922.

The present disclosure provides a multilayer film. In an embodiment, a multilayer film is provided and includes: a layer (A) comprising an olefin-based polymer; a layer (B) that is a tie layer comprising a sulfonamide derivative grafted olefin-based polymer (SD-g-PO); and a layer (C) comprising a polar component.

A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.

A blood storage container for the anaerobic storage of blood, having enhanced sealing methods and materials for the preservation of stored blood is provided.
