1. Manufacturing line for manufacturing a compostable pod for brewing products, said pod being made of complementary first and second half-shell respectively made from a first and second sheet of biodegradable paper-based material, said manufacturing line comprising a first shaping line for shaping the first half-shell and a second shaping line for shaping the second half-shell, each of the first and second shaping lines comprising:
a handling unit for handling the sheet of biodegradable paper-based material; the sheet of biodegradable paper-based material being coated on one side (B), defined as the inner side, with a gas barrier biodegradable polymer, the other side (A) of the sheet being defined as the external side;
a humidifying unit for moistening the external side (A) of the sheet of biodegradable paper-based material;
a forming unit for shaping the sheet of biodegradable paper-based material into a half-shell having an internal side (B) corresponding to the internal side (B) of the sheet of biodegradable paper-based material and an external side (A) corresponding to the external side (A) of the sheet of biodegradable paper-based material;
a drying unit for drying the external side (A) and/or the internal side (B) of the half-shell; and
the shaping line comprises at least one humidity sensor for sensing the level of relative humidity of the biodegradable paper-based material forming the pod at the external side (A) of the pod, said at least one humidity sensor being positioned before or after at least said one of the handling unit, the humidifying unit.
