    摘要： The present invention relates to a method of waterproofing using a layered water sealing article of manufacture including a layer of a flexible sheet material adhered to a layer of a composition comprising a non-hydrated water-swellable clay intimately contacted with a polypropene, polybutene, or mixtures thereof. The water swellable clay composition can be adhered to the flexible sheet material in any manner, such as by extruding the composition in sheet form onto a layer of sheet material. The clay composition layer is sufficiently tacky to adhere to the sheet material on one major surface, and is sufficiently tacky for adherence to a wall or conduit, floor or roof on an exposed major surface in areas of potential water flow to prevent the seepage of water through the bentonite clay composition layer. In one embodiment, the clay composition layer includes a polypropene and/or a polybutene and an elastomer, such as butyl rubber, having sufficient resilience to stretch or expand with the expanding water-swellable clay composition upon hydration and to aid in maintaining the structural integrity and cohesiveness of the clay composition. In another embodiment, the clay composition layer comprises a water-swellable clay, an elastomer, and any plasticizer compatible with the elastomer.

    摘要： In the sealing of a glass container containing a product such as a food product by means of a cover comprising a metal foil having on one surface thereof a sealant layer of a thermoplastic resin, the opening end of the container is preheated, and the cover is placed on the opening end, after which the cover is pressed against the opening end successively by a heating plate and a separate pressing plate. By this process, a positive seal and a high sealing process efficiency are obtained even when the container content is a product such as a heated liquid food product and even when the rim surface of the opening end of the container has some projecting irregularities.

    摘要： Disclosed herein are containers useful for holding fluids, e.g. photographic processing materials, in photographic film units. Such containers have strong seals along certain marginal areas and relatively weak seals along other marginal areas. Such weak seals are designed to open and distribute fluid over a sheet of film or paper when pressure is applied to the container in a camera. Each weak seal is formed from a sealing composition comprising a copolymer of (a) at least about 50 percent, by weight, of a polymerizable monomer having the formula (I): ##STR1## wherein n is an integer of from 0 to 3; R.sup.1 is hydrogen or alkyl; and R.sup.2 is hydrogen, alkyl or phenyl; with (b) a copolymerizable monomer having the formula (II): ##STR2## wherein R.sup.3 is alkyl. This copolymer has a glass transition temperature of at least about 80.degree. C.

    摘要： A heat-sealing sheet material can be obtained by forming, on one side of a sheet base material such as aluminum foil, a sealant layer composed of a graft copolymer comprising a trunk polymer of a 20 to 60% saponification product of an ethylene/vinyl acetate copolymer having a vinyl acetate content of 15 to 45% by weight and a branch polymer of an unsaturated carboxylic acid in a proportion of 10% by weight or less of the partially-saponified product. This sheet material exhibits excellent heat-sealing strength with respect to glass containers, and, moreover, there is almost no decrease in the sealing strength even when the material has been in contact with water. Accordingly, the sheet material is suitable as a sealing material for the opening rims of glass containers for water-containing food products such as jams and pickles.
