# solutions/paper/ perfect packaging with cost reduction for packaging material

In the heat-shrinking phase, in fact, the press promotes the complete escape of any air residue between the layers of the pack, and thus in the cooling of the film a total and monolithic seal of the product is obtained. The phases that follow each other - heat shrinking with consequent cooling and pressing, and the use of a single sheet - guarantee total compactness without fragility points. To complete the line, there is a labeling machine – conceived by the R&D department of Messersì Packaging- prepared for A3 and A4 formats on one or more sides that recognizes each package traceability, history and destination. The machine uses a gluing device with hot glue that guarantees its tightness. The system is able to cope with any production variability, in terms of size and type of pack - obtains the objective of creating a high performance packaging for unmatched mechanical and aesthetic strength, and thanks to content and optimized use of the material also leads to considerable savings.
