Disposable Protective Garment And Barrier film
A disposable protective garment for positioning over a wearer's head is provided for use in airplanes, busses, trains, other mass transit and other single-use applications. The disposable protective garment includes a hood formed of tubular blown film that has an at least partly closed top that rests on a wearer's head and an open bottom that rests on a wearer's shoulders. A mask can be integrated into the hood by forming a plurality of apertures in the hood and placing a polymer fabric that acts as a filter over the plurality of apertures. The hood may alternatively be combined with a crown or air filter material positioned over its top; a tubular filter equipped with an electric fan that draws air from above, filters it and directs the clean air downward across the wearer's face; and/or headgear. A barrier film suitable for use in the protective garment as well as other barrier applications is also provided.
RESIN COMPOSITION, MOLDED BODY, AND THEIR APPLICATION
Provided are a resin composition having excellent oxygen barrier property under high humidity as a novel resin material, a molded body, a method for producing a molded body, and a method for producing a pellet using the resin composition. The resin composition includes a resin component and a plate-shaped talc having an aspect ratio of more than 18, 80 mass % of the resin component comprising a barrier resin having an oxygen transmission coefficient of 5.0 cc.Math.mm/(m.sup.2.Math.day.Math.atm) or less as measured according to ASTM D3985 at a relative humidity of 60% and a temperature of 23° C., and a content of the plate-shaped talc being from 3.0 to 55.0 mass % when a total of the barrier resin and the plate-shaped talc is 100 mass %.
DECORATIVE SHEET AND DECORATIVE MATERIAL USING SAME
Provided is a decorative sheet comprising a base material layer, a transparent resin layer and a surface protection layer in the presented order, wherein at least one of the base material layer and the transparent resin layer is constituted by a resin composition comprising a resin having an ultraviolet absorption wavelength at least at 270 to 300 nm; absorbance All of the surface protection layer at wavelengths from 270 to 300 nm is 0.6 or more; and absorbance A.sub.12 of the transparent resin layer and the surface protection layer at wavelengths from 270 to 300 nm is 2.7 or more, and wherein the decorative sheet can suppress time-dependent degradation caused by ultraviolet ray, and has excellent weather resistance. Also provided is a decorative material obtained using the decorative sheet.
LAMINATING FILM RESISTANT TO DISCOLORATION CAUSED BY COOKING, AND FILM-LAMINATED METAL SHEET
A blended polyester laminating film resistant to discoloration caused by cooking, comprising polyethylene terephthalate and polybutylene terephthalate. The blended polyester laminating film comprises three layers, i.e., upper, middle, and lower layers. One surface layer contains SiO.sub.2 in a mass fraction of 1200-2000 ppm added by in-situ polymerization. The blended polyester laminating film is manufactured by a three-layer coextrusion biaxial stretching method, and the manufacturing method is 240-275° C. A film-laminated metal sheet manufactured from the blended polyester laminating film has excellent resistance to discoloration caused by cooking, and is applied to metal containers for food and beverage packaging that require high-temperature sterilization.
Package and film
A package includes: a film including a crystalline stretched oriented film; and a breaking portion provided in the film and including one or more non-oriented portions formed by heating a part of the crystalline stretched oriented film at a temperature equal to or higher than a melting point of the crystalline stretched oriented film and facing each other with an oriented portion of the crystalline stretched oriented film interposed therebetween.
High temperature thermostable foodservice tray
An example disposable food service tray that can withstand high heat is disclosed. The disposable food tray includes a first layer comprising paper board, and a second layer comprising polyethylene terephthalate (PET) affixed to the first layer, wherein an adhesion between the first layer and the second layer is configured to withstand a temperature of up to 525 degrees Fahrenheit for up to six minutes without blistering.
COMPOSITE STRUCTURES FOR PACKAGING ARTICLES AND RELATED METHODS
The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.
LOW ADSORPTION SEALANT FILM, LAMINATED BODY AND PACKAGING BAG
The invention provides a sealant film that is less likely to adsorb components formed of various types of organic compounds, has excellent heat sealing characteristics at 140° C., while having low heat sealing strength at 100° C. and being less likely for heat sealing layers to adhere to each other even when the film is used as a packaging bag and the content thereof is warmed in boiling water. The sealant film has at least one heat sealing layer consisting of a polyester component, wherein a heat sealing strength of the heat sealing layer being heat sealed to another heat sealing layer at 100° C. and 0.2 MPa for 2 seconds is 0-5 N/15 mm and at 140° C. and 0.2 MPa for 2 seconds is 8-30 N/15 mm, and a film density including all layers is 1.20 or more and less than 1.39.
Compositions and films comprising polylactic acid polymer, polyvinyl acetate polymer and plasticizer
A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.
RECYCLABLE LABELS
