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.
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 top surface toward 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,
A polypropylene sheet for preparing a thermoformed object comprising a top surface and a bottom surface, wherein the sheet comprises one or more groove(s) on the bottom surface that are positioned to allow the sheet to be broken along the groove by bending the sheet towards the top surface, wherein each of the groove(s) has a maximum depth of ≥40% and ≤80% with regard to the thickness of the polypropylene sheet, wherein the polypropylene sheet comprises between 0.04 wt % to 0.08 wt % of the advanced nucleating agent (1R,2R,3S,4S)-bicyclo[2.2.1]heptane-2,3-dicarboxylic acid, disodium salt, with regard to the total weight of the polypropylene sheet, and
A process for manufacturing of a package, comprising the steps in this order of:
