The invention provides a stretch blow molded container formed from a thermoplastic resin material which comprises polyglycolic acid having (a) a repeating unit represented by the following formula (1): ##STR1## (b) a melt viscosity, .eta.* [as measured at a temperature of (the melting point, Tm of the polymer+20.degree. C.) and a shear rate of 100/sec] of 500-100,000 Pa.multidot.s; (c) a melting point, Tm of at least 180.degree. C.; (d) a melt enthalpy, .DELTA.Hm of at least 20 J/g; and (e) a density of at least 1.50 g/cm.sup.3 as measured in an unoriented, crystallized form, wherein the stretch blow molded container has tensile strength (in a circumferential direction) of at least 100 MPa and a carbon dioxide permeability (as measured at a temperature of 23.degree. C. and 80% relative humidity; in terms of the thickness of 50 .mu.m) of 300 cc/m.sup.2 .multidot.day.multidot.atm or smaller at the body sidewall thereof, and a production process thereof.
