Abstract: The multilayer container of the present invention comprises an outermost layer, an innermost layer and at least one intermediate layer interposed between the outermost layer and the innermost layer. Each of the outermost and innermost layers is mainly made of a thermoplastic polyester resin A produced by polymerizing a dicarboxylic acid component comprising 80 mol % or higher of terephthalic acid with a diol component comprising 80 mol % or higher of ethylene glycol. At least one of the intermediate layers is mainly made of a mixed resin B of a polyamide resin C and a polyamide resin D in a mixing ratio of 99.5/0.5 to 80/20 by weight. The polyamide resin C is produced by polymerizing a diamine component comprising 70 mol % or higher of m-xylylenediamine with a dicarboxylic acid component comprising 70 mol % or higher of adipic acid.

Abstract: A stretched polyamide film including at least one stretched layer made of a mixed resin containing a polyamide resin and a modified polyester-based elastomer Y. The polyamide resin X is mainly constituted by m-xylylenediamine unit and C6-12 ?,?-aliphatic dicarboxylic acid unit. The modified polyester-based elastomer is graft-modified with an ethylenically unsaturated carboxylic acid or its anhydride. Such stretched polyamide film is drastically improved in the flexibility, impact resistance and pin-hole resistance with little reduction in the gas-barrier properties while retaining an enough transparency to practical use.

Abstract: A stretched film made of a resin mixture of a polyamide resin X with an amorous polyamide resin Y and/or an ionomer resin Z. The polyamide resin X includes a diamine constitutional unit containing 70 mol % or more of m-xylylene diamine unit and a dicarboxylic acid constitutional unit containing 70 mol % or more of C6-C12 ?,?-aliphatic dicarboxylic acid unit. A film produced by melt-extruding the resin mixture can be stretched in a high ratio exceeding 4 times in at least one direction of MD and TD. The highly stretched film produced by the stretching in a ratio exceeding 4 times exhibits good gas-barrier properties and transparency.

Abstract: A method of producing a biaxially stretched, multi-layered polyamide film which includes a step of biaxially stretching a non-stretched laminate film composed of a layer mainly made of a polyamide resin and a layer mainly made of an aliphatic polyamide resin. The biaxial stretching is made by a roll/tenter successive biaxial stretching method. The polyamide resin is composed of a diamine constitutional unit mainly made of m-xylylenediamine units and a dicarboxylic acid constitutional unit mainly made of units derived from an ?,?-aliphatic dicarboxylic acid having 6 to 12 carbon atoms. The non-stretched laminate film is cooled by a cooling roll having a temperature within a limited range and then successively and biaxially stretched. With such a production method, the biaxially stretched, multi-layered polyamide film is excellent in the gas barrier properties, pinhole resistance, flexibility, and impact resistance.

Abstract: The present invention provides a stretched aromatic-polyamide film obtained by stretching aromatic-polyamide resin by a stretch ratio exceeding 4 times in a MD direction and/or a TD direction. The aromatic-polyamide resin includes a diamine constitutional unit containing 70 mol % or more of m-xylylenediamine unit and a dicarboxylic acid constitutional unit containing 80 to 97 mol % of C4-20 linear aliphatic ?,?-dicarboxylic acid unit and 3 to 20 mol % of isophthalic acid unit. The aromatic-polyamide resin has a minimum semi-crystallization time of 40 to 2,000 seconds in a measuring temperature range from the glass transition point thereof to less than the melting point thereof when measured by isothermal crystallization according to depolarization intensity method. The stretched aromatic-polyamide film has excellent gas-barrier properties and transparency.
