Abstract: A composite useful for making trays for the packaging of food and the like is formed from foamed polystyrene and a film bonded to the polystyrene, the film including a bonding layer of a styrene butadiene copolymer, the bonding layer including at least about 25% by weight of butadiene. The composite may be thermoformed into articles such as trays for use in the packaging of food products, especially meat products.

Abstract: The present invention provides a peelable laminate suitable for cook-in packaging and a method of cooking a food product. The method includes the steps of:a) enclosing a food product in the peelable laminate, the peelable laminate having(1) an edible film in contact with the food product, and(2) a protective film peelably adhered to the edible film; andb) heating the enclosed food product to at least partially cook the food product, the edible layer adhering to the at least partially cooked food product with an adhesive strength which is greater than the force required to peel the protective film from the edible film. In this manner, the protective film can be peeled from the edible film after cooking without product loss due to adherence of food particles to the film. Furthermore, the peelable laminate prevents or minimizes cook-out and allows a modifier to be transferred to the food product via the edible film during the cooking process.

Abstract: A polymeric film includes at least one irradiated water soluble layer. A process for making a water soluble film includes the steps of extruding a water soluble film; and irradiating the water soluble film. Using electron beam irradiation, a water soluble film's solubility rate can be increased.

Abstract: A peelable laminate comprises a water soluble substrate and a water insoluble web peelably adhered to the water soluble substrate. The peelable laminate can be made by e.g. coextrusion or lamination processes, and used to package fertilizer, caustic materials, and other products. A process for making the laminate, and a package made from the laminate are also disclosed.

Abstract: An apparatus and method effect cleaning of a grooved applicator cylinder which applies molten size to textile strands, such as spun yarns. A plurality of holding blocks have quadrate-shaped channels formed in one end thereof, and a circular cross-section elongated elastomeric material cord (e.g., silicone rubber having a Durometer of about 50-75) is frictionally received within the channel. The position of the holding blocks with respect to a housing may be individually adjusted utilizing a cam slide having a slanted surface which engages an adjustment screw, tightening of the adjustment screw sliding the holding block toward the cylinder. The elastomeric material of the cord deforms to essentially completely fill the grooves and to wipe unused size, lint and the like from the grooves and adjacent lands, including the bottoms of the grooves, to effect cleaning. The housing is beveled to facilitate flow of removed size thereover.

Abstract: Textile fabrics such as polyester, nylon and high-tenacity nylon are continuously dyed using a non-aqueous dye composition at elevated temperatures in an air atmosphere. The non-aqueous dye composition consisting of high-boiling, nonionic solvent and a dye, is applied to the textile in an air atmosphere at a temperature below 280.degree. F. then, while the dye composition is entrained in the fabric, the fabric is heated also in an ambient atmosphere to effective dyeing. Non-reactive environments or inert temperatures are not required.

Abstract: Textiles, especially polyester, nylon and high-tenacity nylon, are continuously dyed in an organic medium containing a high-boiling, nonionic solvent admixed with one or more lower-boiling organic solvents and at least one dyestuff dissolved in the solvent media. The lower-boiling solvent acts as a carrier to entrain the dye and allows the dye to enter the fiber evenly. The non-aqueous dyestuff medium allows the process to be conducted above the boiling point of water which facilitates dye penetration into the fiber and, in turn, shortens the dyeing process. Atmospheric pressure may be used, thus avoiding the constraints of a batch-type operation of pressurized dyeing procedures, as is conventionally used in this art. Fabric may be dyed in open width under restraint at elevated temperatures thereby achieving uniform coloring of the fabric without shade variations from end-to-end or "tailing".
