摘要： A multilayer container including: an outermost layer (1) containing a propylene-based polymer A containing homopolypropylene as a main component having a melt flow rate in a range of 2.0 to 10.0 g/10 min; an inner layer (2) containing 50 to 99% by weight of a propylene-based polymer B containing homopolypropylene as a main component having a melt flow rate of not more than 5.0 g/10 min and an isotactic index of not less than 93%, and 1 to 50% by weight of an ethylene-α-olefin copolymer C; and a barrier layer (4) occupying 5 to 20% by weight of the whole container. The ratio (L/D) of container height (L) to diameter (D) is not less than 0.5, and a volume shrinkage based on volume measured before and after heat sterilization at 121° C. for 30 minutes is not more than 5%.

摘要： The disclosure makes it possible to provide a cell culture membrane capable of easily decomposing after allowing cell layers to be formed on both sides of the cell culture membrane. A cell culture membrane having a cell culture region at both surfaces thereof, the cell culture membrane containing methyl cellulose having a weight average molecular weight of from 20000 to 190000 as a main component, or containing methyl cellulose having a weight average molecular weight of from 190000 to 400000 as a main component, and further containing a dissolution temperature regulator. The dissolution temperature regulator is preferably at least one of sodium styrenesulfonate, sodium iodide, or sodium toluenesulfonate. A poorly soluble material is preferably added to the cell culture membrane.

摘要： An article represented by a container that is formed of a thermoplastic resin blended with a metal or a metal compound that can react with a corrosive gas or a volatile sulfur compound and give a color. The thermoplastic resin includes at least one metal selected from three metals of Zn, Sn and Mn or one metal compound thereof, and a metal or a metal compound that is not any of these three metals and that can react with the corrosive gas or the volatile sulfur compound and give a color. The metal selected from the three metals or the metal compound functions as a scavenger for the corrosive gas or the volatile sulfur compound.

摘要： A gas-barrier multilayered container having (i) a layer of a propylene type polymer which chiefly includes a homopolypropylene having an isotactic index of not less than 93%, and (ii) a layer of an ethylene-vinyl alcohol copolymer having not less than two crystal melting peak temperatures. Also disclosed is a lustrous and shock-resistant multilayered container having at least (i) an outermost layer of a propylene type polymer A which chiefly includes a homopolypropylene having a melt flow rate of 2.0 to 10.0 g/10 min., and (ii) an inner layer of a propylene type polymer B which chiefly includes a homopolypropylene having a melt flow rate of not more than 1.0 g/10 min.

摘要： A multilayered container having an intermediate layer that contains a resin composition B obtained by blending a resin composition A that contains at least a resin (a) having a hydroxyl group with a carboxyl compound (b) of which the α-carbon is quaternary and of which the carboxyl group is forming no metal salt, wherein a ratio (COOH/OH) of the amount of the carboxyl groups of the carboxyl compound (b) to the amount of the hydroxyl groups of the resin (a) in the resin composition A is not more than 0.4 The multilayered container maintains excellent anti-eluting property and flavor-retaining property even when it is subjected to the retort sterilization.
