The invention provides a hollow fiber membrane exhibiting a favorable gas permeation performance and an excellent heat resistance in which the generation of pinholes are suppressed, and a hollow fiber membrane module using the same. The hollow fiber membrane comprising a gas permeable nonporous layer; and a porous supporting layer to support the nonporous layer formed of a thermoplastic elastomer having a DSC melting peak temperature of 130&#xb0; C. or higher and a rupture elongation prescribed in ISO 37 (2010) of 300% or more.

Hollow fiber membrane and hollow fiber membrane module

The present invention provides and a plastic container and multilayered films, which comprises a heat-sealable seal layer, a cyclic polyolefin layer, and an outermost layer, wherein the seal layer comprises polypropylene, the cyclic polyolefin layer comprises a cyclic polyolefin polymer or a cyclic polyolefin copolymer, and the outermost layer comprises a layer containing polypropylene, and which further comprises a resin composition layer comprises a blended product of a propylene polymer and a styrene elastomer. The plastic container of the present invention can suppresses a reduction in the medicament content of a liquid-state medicament and is excellent in terms of shock resistance, handling ability during the filling of the container with the medicament, and the moldability and transparency of the container.

Plastic container comprising cyclic polyolefin layer

The present invention provides a hydrogenated block copolymer which has an excellent balance in a transparency, optical property, flexibility, mechanical property, moldability, heat resistance, gas barrier property, low moisture absorbency and non-adsorptive property of chemical. Also, the present invention has an object to provide a resin composition containing the hydrogenated block copolymer as a resin component, and a film and container containing the composition. The present invention relates to a hydrogenated block copolymer containing a Block A of a hydrogenated vinyl aromatic polymer and a Block B of a polymer containing isobutylene.

Hydrogenated block copolymer, resin composition, film and container

Multi-chamber container () having its interior partitioned by weak seal portions () provided through detachable heat sealing so that multiple contents are accommodated separately from each other, wherein use is made of heat seal layers consisting of a composition comprising two types of propylene copolymers components (component A and component B) from propylene and ethylene and/or a C-C&#x3b1;-olefin which have the following elution properties. Thus, a region wherein a change of seal strength by a change of heat seal temperature is small has a wide temperature range to thereby facilitate controlling of the seal strength at the weak seal portions. The proportion (mass %) of, to total solution, elution according to the TREF method (temperature: 0 to 140&#xb0; C. and solvent: ODCB) is as follows. With respect to component A: 15 to 50 at 0&#xb0; C., and 5 to less than 15 at 60 to 90&#xb0; C. With respect to component B: 0 to 25 at 0&#xb0; C., and 15 to 70 at 60 to 90&#xb0; C.

Multi-chamber container

An adhesive sheet for dicing comprising a base film provided at least one surface thereof with an adhesive layer, wherein the base film comprises an olefinic thermoplastic elastomer comprising propylene and ethylene and/or &#x3b1;-olefin including 4 to 8 carbon atoms as polymerization components, and the peak melting temperature of the olefinic thermoplastic elastomer is 120&#xb0; C. or more, is free of economical disadvantages with less reduction in the quality level of products and less generation of fibrous off-cuts during dicing. In particular, fibrous off-cuts occur less during dicing when the base film contains a crystal-nucleating agent. Further, generation of chippings during dicing can be prevented by incorporation of an ethylene series polymer into the base film.
