Said thermoformed sheet comprises a plurality of cavities in which the product to be packaged has previously been deposited inside. Once said cavities are sealed and separated from the sheet, the container is obtained. Generally, after the filling stage of the cavities of the thermoformed sheet Ie there is a sealing stage thereof and a subsequent cutting stage that separates said cavities from the thermoformed sheet and that deposits the containers obtained on transport means that transfer said packaging towards a later stage of packaging of the same for his expedition.

  • Said closure film has a heat sealable coating on at least one of its faces which makes it suitable for being heat welded. Since this welding system is produced by heat, the closing film is heated and tends to have uncontrollable deformations that often displace the cord of welding. This presents an important problem in the next cutting stage. Specifically, when the thermoformed sheet faces this stage, it is found with cutting means in a fixed position, while as explained, the welding bead has suffered an uncontrolled and therefore indefinite displacement.
