Abstract: A beverage capsule (101), a method of lidding a beverage capsule (101) and a sealing head (115) are disclosed. A capsule body and a lid (110) of the beverage capsule (101) together define an internal volume for containing beverage ingredients. A peripheral flange (105) of the capsule body comprises or consists of a thermoplastic polymer, the peripheral flange prior to sealing with the lid having a flat receiving surface (106). The lid (110) also comprises a thermoplastic polymer. The lid (110) is sealed to the peripheral flange (105) to form a first peripheral seal able to withstand pressurisation of the internal volume during use. The first peripheral seal comprises a weld between the thermoplastic polymer of the capsule body and the thermoplastic polymer of the lid (110). A face of the peripheral flange (105) in contact with the lid (110) comprises a recess formed into the flat receiving surface (106) and the lid (110) is sealed to the peripheral flange (105) within the recess.
