Definitions

• the present invention relates to the field of batch packaging of containers.

• the containers can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blowing operation in the case of a plastic bottle, followed by filling then closing with a cap and labeling. At the end of these treatments, the containers are said to be “finished”.
• each group is coated, in particular covered with a film, in order to hold the containers together and to facilitate the handling of such a batch thus obtained.
• a coating can be carried out through a bundling step.
• bundling a group of containers consists of wrapping it using a sheet of plastic film made of heat-shrinkable material.
• a coated group then undergoes a heating step so that the sheet matches the overall exterior shape of the containers.
