<p>PURPOSE:To obtain an economical hollow molding with excellent transparency, molding, and gas barrier by highly drawing a resin composition consisting of polyethylene terephthalate resin and at least a kind of resin composition selected from a specific resin or copolyester group. CONSTITUTION:A hollow molding 1 is formed by highly drawing a resin composi tion consisting of polyethyleneterephthalate resin (A) and at least a kind of (B) selected from polyethylenenaphthalate resin, polyethyleneisophthalate resin or copolyester of terephthalic acid, 2.6-naphthalenedicarbonic acid and ethyleneglycol, and copolyester formed respectively through esterification of terephthalic acid, ethyleneglycol and cyclohexanedimeethanol, or neopentilglycol or diethyleneglycol, and copolyester of terephthalic acid, aliphatic dicarbonxylic acid of 6 - 10 carbon numbers and ethyleneglycol as shown in formula 1 in which the drawing index is 130cm or more.</p> |
