摘要： The present invention relates to an integrated process for the production of polyester tape, comprising the steps of a) preparing feed polyester comprising a polymerisation reaction in one or more reactors in series and measuring the viscosity of the obtained feed polyester, b) feeding the feed polyester obtained from step a) and optional additives to a melt mixing device, mixing said feed polyester and said optional additives so as to form a molten polyester composition and measuring the viscosity of the obtained polyester composition, c) extruding the molten polyester composition through a film extrusion die thereby forming a molten film of said polyester composition, d) preparing a polyester tape from said molten polyester film, said preparing comprising trimming the edges of the film at a stage where said film is below its melting temperature, e) feeding at least a part of the trimmed edges obtained in step d) in-line to the melt mixing device in step b) wherein the amount of trimmed edges and optional further additives fed to the melt mixing device in step b) is controlled on the basis of the measured viscosity of the polyester composition.

摘要： The present invention provides a multi-cup arrangement comprising a polypropylene sheet, wherein the polypropylene sheet comprises at least two cavities, the cavities each protruding from the sheet from a bottom surface of the sheet, wherein the cavities are separated from each other via one or more spacer area(s) on the sheet, wherein the spacer area(s) each comprise one or more groove(s) on the bottom surface of the sheet that are positioned to allow the sheet to be broken along the groove by bending the sheet towards the top surface, wherein the grooves are positioned to divide the sheet into multiple segments, each segment comprising one or more cavities, wherein each of the groove(s) has a maximum depth of ≥25% and ≤80% with regard to the thickness of the polypropylene sheet. Such multi-cup arrangement may be separated into individual cup segments by moderate manual force, whilst the arrangement does not undesirably bend nor snap under the action of its own weight.
