Roof for shaker cups Roof for Ø95 mm jars / flat Our PVC pots are used in cold catering, represented by round bowls (e.g. a chocolate dish as a dessert dish) and chalices, popular among dairy farmers. The latter are used as custard and yoghurt cups, but are also suitable for packaging curd and butter. PVC pots are usually recognisable by the fact that they are bluish in colour when used in bulk (whole pack). They are practical as they are disposable/disposable so you don't have to worry about washing them. They can be stacked on top of each other.
