Multi-cup arrangement for foodstuff packaging

Номер: US20210179311A1
Принадлежит: SABIC Global Technologies BV

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.
