Abstract: The present invention is related to a method for the direct production of polyester articles for packaging purposes, in particular for the production of hollow bodies, thermoformed sheets and films, said articles containing an amount of acetaldehyde less than 10 ppm. This method is characterised in that it essentially comprises a step in which the initial level SE0 of the sum of end groups in the polymer melt is increased by adding a mixture of at least one inert and at least one reactive substance to said polymer melt to a second level SE1 and a degassing step consisting in essentially applying a vacuum to the previously obtained polymer melt to cause a removal of low molecular weight substances present and formed, of non reacted reactive substance(s) and inert substance(s) added during previous step before the so obtained polymer melt is directly converted into the desired articles.

Abstract: Method of producing a polyester resin container, such as a PET bottle, from a preform (10) includes a step whereby the preform (10) is heated to a temperature above a glass-transition temperature and a drawing step which is performed in a cavity (101). According to the invention, during the drawing step, an incompressible fluid and not a gaseous fluid is injected through the opening in the preform (10?).

Abstract: The present invention relates to a container (1) for a liquid or viscous product, comprising a substantially ovoid or spherical container body (2) having a diameter D1, and a neck (3) having a diameter D2, said neck comprising a dispensing opening and means for allowing closing means to be attached thereto, D1 being greater than D2, said container (1) being made out of semi-cristalline PET, the walls of 10 said container body (2) having a thickness inferior or equal to 100 ?m at least in the middle-height region of said container. In a highly preferred embodiment of the invention, the container body comprises at least two opposite flat, substantially vertical, surfaces (8), and a flat, substantially horizontal, surface (9) located opposite the neck and forming a bottom side.
