| titleOfInvention | METHOD FOR MANUFACTURING POLYESTER BIETIRE FILM |
| abstract | The invention relates to a process for manufacturing a polyester film, preferably a polyethylene terephthalate PET film, stretched and comprising crystallites; characterized in that it comprises the following steps: (a) Application of granules, based on polyester (15000 and 50000D), and intrinsic viscosity of between 0.4 and 1.3 dL / g; (b) drying the granules; (c) Possible mixing; (d) extrusion; (e) Cooling; (f) optional coating; (g) Biaxial stretching of the film; (h) optional coating; (i) Thermofixation; (j) Relaxation; (k) film winding; (1) Finishing; (m) Controlling the performance of the polyester film by a method A measuring impact-tensile strength and / or method B sonic module measurement; (n) Taking into account the measurements of step (m) to modify, if necessary, the parameters of at least one of the following steps: (g) and (i), so as to control the resistance to hydrolysis of the film. The invention also relates to a bi-stretched polyester film obtained by the process according to the invention, having a hydrolysis resistance measured in a PCT test 36h 125 ° C MD and given by the retention percentage AR> 70%; tensile impact strength in kJ / m> 300; and / or a global planar sonic module value GPSM in daN / mm> 470. The invention finally relates to a module, a panel or a photovoltaic cell equipped with at least one film according to the invention. |
