摘要： There is provided a thermally bonded nonwoven fabric with a unit weight of 10 to 40 g/m.sup.2, comprising 20 to 100% by weight of a composite fiber with a fineness of 0.5 to 8 denier and 80 to 0% by weight of other fibers as the constituent fibers, the composite fiber comprising a first component which is an ethylene-.alpha.-olefin copolymer composition comprising an ethylen-.alpha.-olefin copolymer containing 0.5 to 4% by weight of an .alpha.-olefin having 4 to 12 carbon atoms blended with 0.01 to 0.3% by weight of a phenol type antioxidant and 0.01 to 0.3% by weight of a sulfur type antioxidant, having a Q-value (weight average molecular weight/number average molecular weight) of 4 or less, a density of 0.930 to 0.950 g/cm.sup.3, a melt flow rate of 5 to 50 g/10 min. and an oxidation induction time at 210.degree. C. of 10 min. or longer, and a second component which is a thermoplastic resin having a melting point higher by at least 20.degree. C. than that of the first component, with a constitutional ratio (sectional area ratio) of the first component to the second component being 35:65 to 70:30, said first component of the composite fiber forming at least a proportion of the fiber surface continuously along the length of each fiber and adhering through melting mutually the constituent fibers.

摘要： A lid which is to be heat-sealed on a container, including a laminated sheet composed of a base layer, an adhesive layer, a metallic layer, and a heat-sealable resin layer, in which the base layer includes a single layer of a stretched resin film having many microvoids or a laminate containing at least the stretched resin film, the lid having an indication of the direction of stripping, including a lug provided at the periphery thereof or a print thereon, in such a manner that the indicated direction of stripping should be set within a range of .+-.45.degree. with respect to the direction of greatest thermal expansion coefficient of the base layer when heated from 30.degree. C. up to 80.degree. C. at a rate of temperature rise of 10.degree. C./min for 5 minutes. When hot water is poured into a container with the lid partly stripped, the lid is heated by the steam to close the container without assistance.

摘要： A laminated resin sheet comprising (A) a laminated base material composed of (A.sup.1) an expanded resin layer and (A.sup.2) a non-expanded resin layer obtained by co-extrusion of (a.sup.1) a blowing agent-containing thermoplastic resin and (a.sup.2) a filler-containing thermoplastic resin containing 9 to 80% by weight of a filler through a T die, having laminated on at least one side thereof (B) synthetic paper comprising a stretched porous thermoplastic resin film containing an inorganic filler. The laminated resin sheet is light and highly rigid and exhibits a beautiful appearance with satisfactory printability and is therefore useful as various display materials and thermoformable sheeting for food trays, etc.
