A new and improved preform 1 which makes it possible to obtain PEF containers (bottles) having the awaited properties, notably mechanical, by an industrial injection stretch blow molding process. Said preform 1 is of made of a thermoplastic PEF polymer of 2,5-FuranDiCarboxylic Acid (2,5-FDCA) monomer and monoethylene glycol (MEG) monomer and comprises: a neck end 2; a neck support ring 3; and a closed tubular body portion 4; said preform being designed so as to produce, by injection stretch blow-molding, a container, the axial stretch ratio of which is greater than or equal to its hoop stretch ratio. The invention also concerns a plastic container 10, preferably a bottle, obtained by injection stretch blow-molding of PEF preform, said bottle 10 having an axial stretch ratio greater than or equal to the hoop stretch ratio. The method for manufacturing this bottle 10 is also encompassed by the invention. |
