A process and an apparatus for producing closed sealed capsules are disclosed. The capsules contain releasable substances packaged in at least one cavity inside the capsules which are formed of two or more joined sealed parts of substantially organic, film forming material. The process comprises the steps of: (a) providing a first part of the capsule having a first contact zone; (b) filling the first part of the capsule with the substances to be packaged; (c) providing at least a second part of the capsule having a second contact zone; (d) applying binding means to at least one of the contact zones; (e) joining the parts of the capsule, so that the contact zones come into contact via the binding means; and (f) pressing the joined parts of the capsule together with a predetermined force so that portions of opposite contact zones are kept in pressed contact for a predetermined period of time to obtain the closed sealed capsule. Also disclosed is an apparatus for carrying out this process, preferably including a channel (31) having a first opening (56) and a second opening (43) spaced apart from the first opening (56), such that joined parts (21, 22) of the capsules (20) are insertable into the channel (31) through the first opening (56), are guidable along the channel (56) and are ejectable from the channel (31) through the second opening (43), whereby the inserted parts (21, 22) of the capsules (20) form a row such that successive pairs of joined parts (21, 22) stay in direct contact with one another.
