Abstract: 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.

Abstract: The present invention relates to a process for moulding a polymeric object, the process comprising the steps of: (a) providing a substantially flat horizontally positioned layer of a material, the layer being a film or sheet; (b) providing a layer of a thermoplastic powder onto the layer provided under (a); (c) subjecting a pre-defined part of the thermoplastic powder to irradiation to heat the pre-defined part of the thermoplastic powder to a temperature at which the thermoplastic fuses or sinters onto at least a part of the flat layer of material; (d) terminating the exposure to irradiation; (e) providing a further layer of the thermoplastic powder onto the layer provided under (b); (f) subjecting a pre-defined part of the thermoplastic powder of the layer provided under (e) to irradiation to heat the pre-defined part of the thermoplastic powder to a temperature at which the thermoplastic fuses or sinters onto at least a part of the flat layer of the material fused under (c); (g) terminating the exposure to

Abstract: The present invention relates to a sheet comprising polyester, the sheet comprising at least one area (a) wherein the area (a) comprises at least one groove having a depth of >50% with regard to the thickness of the sheet in the area (a), wherein the sheet has a thickness of 200-1000 ?m in the area (a). Such sheet provides the ability to snap along the grooves in a predictable manner, whilst providing sufficient rigidity to avoid undesired bending under the influence of its own weight.
