    • The invention relates to a process for making polyethylene terephthalate (PET) from ethylene glycol (EG), purified terephthalic acid (PTA) and optionally up to 30 mol % comonomer, using a catalyst system essentially consisting of antimony—(Sb), zinc—(Zn) and phosphorous—(P) compounds, comprising the steps of a) esterifying EG and PTA to form diethyleneglycol terephthalate and oligomers (DGT), and b) melt-phase polycondensing DGT to form polyester and EG1 wherein the Sb- and P-compounds are added in step a) and the Zn-compound is added after step a). With this process PET can be obtained that shows favorable color and optical clarity, also if recycling of EG is applied in the process, and a relatively low rate of acetaldehyde regeneration during melt-processing.

    • The invention relates to a Flexible Intermediate Bulk Container (FIBC) having a body made of flexible woven fabric, and integral handling devices, wherein the fabric is woven from opaque oriented polyethylene terephthalate (PET) strips having a density of from 500 to 1300 kg/m3 and a tensile strength of at least 250 MPa.Advantages of said FIBC include directly printability with the usual type of inks, giving excellent contrast and good adhesion, without pre-treatment like a corona- or flame-treatment. The FIBC based on the PET fabric also shows higher gloss; better UV resistance; better mechanical properties, like high tensile strength and creep resistance; favorable abrasion resistance; and higher temperature resistance than a conventional big bag based on polypropylene strips.The invention further relates to such a FIBC based on stress-whitened PET tapes obtained by a special drawing process.
    • 本发明涉及一种具有由柔性织物制成的主体的柔性中间散装容器(FIBC)和一体式处理装置,其中织物由密度为500至1300kg / m 2的不透明取向的聚对苯二甲酸乙二醇酯(PET) m3,拉伸强度至少为250MPa。 所述FIBC的优点包括使用通常类型的油墨直接印刷,具有优异的对比度和良好的附着力,无需进行电晕或火焰处理的预处理。 基于PET织物的FIBC也具有较高的光泽度; 更好的抗紫外线; 更好的机械性能,如高抗拉强度和抗蠕变性; 耐磨性好; 耐高温性比传统的基于聚丙烯条的大袋子。 本发明还涉及通过特殊拉伸工艺获得的基于应力增白PET带的这种FIBC。
