Method and packaging machine for manufacturing a compostable pod for brewing products and compostable pod for brewing products

A method for manufacturing a compostable pod for brewing products, the method comprising:

• preparing a first sheet and a second sheet made of biodegradable material with gas barrier properties;
• shaping the first sheet to make at least a first concave portion;
• shaping the second sheet to make at least a second concave portion;
• after shaping the first concave portion and the second concave portion, filling the first concave portion with a predetermined quantity of brewing product;
• joining the first concave portion to the second concave portion so that the respective concavities are opposite one another and define a casing for the brewing product;
• the shaping steps of the first sheet and of the second sheet comprising:
• moistening at least a portion of the first sheet and a portion of the second sheet;
• after moistening the portion of the first sheet and the portion of the second sheet, configuring the portion of the first sheet and the portion of the second sheet to make the first concave portion and the second concave portion;
• and
• after configuring the portion of the first sheet and the portion of the second sheet, drying the first concave portion and the second concave portion, wherein the drying is carried out by a heating member configured to dry the first concave portion and the second concave portion so that concave configurations of the first concave portion and the second concave portion is maintained,
• the biodegradable material comprises a plurality of superimposed layers comprising (i) a non-woven fabric comprising at least 40% biodegradable fibres by weight of the non-woven fabric and (ii) a layer of adhesive suitable for contact with foodstuffs.
