Abstract: Disclosed is a process for drawing plastic laminates, which comprises draw-forming a laminate comprising a layer of a polyester composed essentially of ethylene terephthalate units, a gas barrier layer of an olefinvinyl alcohol copolymer and an adhesive layer interposed therebetween under temperature and draw ratio conditions satisfying a requirement represented by the following formula: ##EQU1## wherein X stands for the area draw ratio (%) defined by the formula of X=100(tho/th-1) in which tho stands for the thickness of the laminate before draw forming and th stands for the thickness of the laminate after draw forming, Y stands for the vinyl alcohol content (mole %) in the olefinvinyl alcohol copolymer, and t stands for the draw forming temperature (.degree. C.).
