Paper-Based Flow Packs – Heat Sealing

The ideal solution for heat sealing of paper-based flow packs – in the high-performance range. Where speeds of 80 to 120 m/min are otherwise possible for modern foils in this range, an impressive 90 m/min is achieved for the paper-based packaging material on the FPC5. Thanks to this solution, the machine can now produce a flow pack package made of barrier paper with integrated heat-sealing capability and a pure paper content of at least 95 percent. Optimal processing of paper-based packaging on the FPC5 is achieved by precisely preheating the longitudinal sealing and cross-sealing areas of the paper. For this purpose, the sealing area is already preheated during the unwinding process. Thanks to a technically sophisticated pre-drawing section, the paper does not deform during this step. In this way, the paper reaches a higher initial temperature in selected places before the chocolate bars are packaged and heat-sealed. This appreciably reduces the amount of time for which heat must therefore be applied to the paper via the sealing tools during the actual sealing process to achieve the optimum sealing temperature.
