Abstract: A method and apparatus for packaging products such as foodstuffs in which containers are made by heat deforming a band of thermoplastic material in which the band is deformed, the containers are filled, and a metallic cover coated with a thermoplastic material is secured to the filled container in a pressurised environment for example, in the presence of superheated dried steam. The containers are cooled in a connected chamber prior to leaving a housing in which the environment is produced and cutting of the containers from the band and one another.
