A resin composition contains: (A) an ethylene-vinyl alcohol copolymer, (B) a polyester resin, and (C) a sorbic acid ester; wherein the sorbic acid ester (C) is present in an amount of 0.00001 to 10 ppm based on the weight of the resin composition. The resin composition exhibits excellent thermal degradation resistance reduced susceptibility to coloration.

A semicrystalline copolyester resin composition formed by twin screw extrusion of various ingredients includes copolyester resins, antiblock, slip and antifog additives. This semicrystalline copolyester resin can be extruded on to PET film or coextruded with PET resin to form clear PET films with antifog properties. These films with antifog properties are produced in a single step without the use of solvent and does not involve any secondary step for coating a separate antifog layer. This minimizes the cost and time required by a converter to make such clear antifog films. These films containing the heat seal copolyester resin can be heat sealed to clear APET trays. Contents within the trays, such as food, can be seen without fogging on the inside of the film that is used to seal the tray. The seals are strong and the peels are smooth giving a very good packaging performance.

Aspects of the present disclosure relate to compositions and processes suitable for use in forming a lid for a hot food or beverage container, the lid being made from a multi-layer sheet that includes a substrate layer and a cap layer made from polyolefin-based compositions. The lid has a density less than water at 23° C., allowing the lid to be recycled in a recycling stream.

The present invention relates to a flexible membrane lid for a container comprising a top paper layer which is perforated to form a perimeter of at least one peelable portion and a bottom film layer. In some embodiments, the bottom film layer is partially adhered to the top paper layer, wherein the layers are not adhered within the perimeter of the peelable portion. In other embodiments, the layers are adhered with a pressure sensitive adhesive within the perimeter of the peelable portion and with a permanent adhesive in the remainder of the area between the top paper layer and bottom film layer. In other embodiments, the invention relates to a flexible membrane lid for a container comprising a top paper layer comprising a pull tab and a bottom film layer which is removably adhered to the top paper layer, wherein bottom film layer comprises a separate pull tab.

Recyclable films having a first layer containing a polyethylene, a second layer containing a high-density polyethylene and a hydrocarbon resin, and a third layer containing a polyethylene may be used for thermoforming packaging components. Both the first and third layers have an overall density between about 0.92 g/cm.sub.3 and 0.97 g/cm.sub.3. The film structure is advantageous as it can be more easily thermoformed than traditional high-density polyethylene films and can maintain the shape taken during thermoforming, exhibiting minimal warping or shrinking.

A method for manufacturing at least one elastomeric article is provided. The method includes placing into a mold an assembly of an uncured elastomeric sheet, a first film fully covering the elastomeric sheet and a second film covering the first film, such that the second film is in contact with and positioned between the first film and an interior surface of the mold. The method further includes curing the assembly in the mold, such that the first film is laminated onto the elastomeric sheet thereby forming the at least one elastomeric article.

The present invention relates to floating roofs for tanks that are used for storage of flammable liquids, such as petroleum or refinery products such as diesel, kerosene, gasoline, etc. In one aspect, the present invention concerns a method for forming a fire retardant coating of a floating roof, and a floating roof obtainable thereby. In another aspect, the present invention relates to improvements in structure of a floating roof. The floating roof tank may be a seamless composite floating roof tank for refineries.

A resin composition for a sealant, comprising an ethylene/polar monomer copolymer (A), an adhesion-imparting resin (B) and a 4-methyl-1-pentene/α-olefin copolymer (C), a content of the 4-methyl-1-pentene/α-olefin copolymer (C) being from 1% by mass to 20% by mass with respect to a total mass of the resin composition for a sealant.

Composite materials, and sealing foils prepared with such composite materials for sealing a container, where the composite materials include an inner layer configured to face the container during sealing, the inner layer being single- or multi-layer, and including a self-contained and closed weakening line; an outer layer that may be single- or multi-layer, and that is configured to be peeled from the inner layer; where an area of the inner layer delimited by the closed weakening line remains attached to the outer layer when the outer layer is peeled from the inner layer, thereby creating a hole in the inner layer; the outermost of the inner layers is in contact with the outer layer, and includes a semicrystalline ethylene-propylene copolymer that is substantially free of dienes; and the innermost of the outer layers is a barrier layer or a lacquer.

A composite package includes a first container and a second container. The first container includes a fiber-based component. The second container includes a film component and forms a primary product cavity of composite package. The film component includes a mineral oil barrier and a sealant. The mineral oil barrier includes a polymeric film, an inorganic oxide coating, and a layer. The inorganic oxide coating is located on the polymeric film. The layer includes a vinyl alcohol polymer. The vinyl alcohol polymer is located on a surface of the inorganic oxide coating.
