L'invention concerne également un procédé pour produire un emballage, selon lequel une bande de matériau (8) est transportée de manière cadencée le long d'une machine d'emballage (1) et une ou plusieurs cavités d'emballage sont façonnées par cycle dans la bande de matériau (8). Les cavités d'emballage sont ensuite remplies avec un produit à emballer, puis un film de recouvrement (14) est scellé sur les cavités d'emballage, le vide étant créé et/ou un échange gazeux étant éventuellement réalisé dans la cavité d'emballage avant scellage.
