ABSTRACT:
Polyvinyl chloride bottles of thin-wall construction are characterized by low oxygen and carbon dioxide permeability and a minimum amount of total additives and, in particular, a low thermal stabilizer content; in addition these bottles have improved tensile and bursting strength, elasticity, and drop resistance making them most suitable for containing oxygen sensitive and carbonated beverages. The bottles are made by forming a preform, comprising at least 70% vinyl chloride polymer material, at a temperature within the thermoplastic temperature range of the material, adjusting the temperature of the preform to within its thermoelastic range from 90.degree.C. to 140.degree.C., and biaxially stretching the preform by rapidly blow molding it to the dimensions of the mold achieving rates of stretch between about 100% and 1000% and above per second. Best orientation is obtained when the preform is stretched within 3 seconds and at a temperature in the thermoelastic range where the stretching capacity of the preform exceeds about 225%.
