A breakable sachet and method of manufacturing same is described. The sachet is formed from layers (11, 12, 13) of plastics film sealed so as to form a reservoir (19). The sachet further incorporates a semi-rigid layer (11) which is scored or weakened (15) so that when the semi-rigid layer is bent, it fractures along the score (15) and the contents of the reservoir can be expelled via a hole (16), formed proximate the fracture point, in controlled manner. A method of manufacturing the sachets includes forming a vertical reservoir which includes a semi-rigid layer (33), the reservoir is partitioned by means of a hot roller (34, 35) and the webs (31, 32, 33) forming the reservoir and sealed to the semi-rigid layer (33) include a hole (16) formed therein. The semi-rigid layer (33) includes a score or weak point (15).
