Perforation applications can be performed so that products packaged side by side, with equal spacing, or throughout the entire film can be opened easily and in one piece by the consumer, particularly in the case of multi-layer flexible food packaging, and powdered products do not scatter around when opening. Barrier properties of the film are protected as much as possible during the perforation application. This application allows Intermat Packaging to offer to its business partners packages that can be opened more easily by their customers.
