Theegarten-Pactec has further developed its FPC5 modular packaging machine for packaging chocolate products: it can now process paper-based tubular bags using a heat-sealing process in the high-performance range.<\/p>\n

The FPC5 packaging machine for bar and tablet products in tubular bags can process paper-based packaging materials using both the standard cold-sealing process and the heat-sealing process. With the Heat sealing of paper-based packaging<\/strong> It operates in the high-performance range: where otherwise speeds of 80 to 120 m\/min are possible for conventional films in this range, the company says that the paper-based packaging material can be produced at a speed of 80 to 120 m\/min. Output of 90 m\/min<\/strong> is achieved. According to Theegarten-Pactec, this corresponds to 600 larger 40g chocolate bars per minute.<\/p>\n

With the new solution, the machine can now be used to produce flow-wrap packaging from Barrier paper with integrated heat sealability<\/strong> and a pure Paper content of at least 95 per cent<\/strong> can be produced. Due to the low proportion of sealing material and barrier layer against grease, moisture or other environmental influences, the packaging produced can be disposed of in the paper waste stream. Fully recycle<\/strong> and recycled for new applications.<\/p>

The processing of the paper-based packaging on the FPC5 is achieved by precisely preheating the longitudinal sealing area and the cross-sealing area of the paper. Preheated during the unrolling process<\/strong>. Thanks to a technically sophisticated pre-drawing section, the paper is not deformed during this work step. This means that the paper reaches a higher initial temperature at certain points before the chocolate bars are packaged and heat-sealed. During the actual sealing process, heat must therefore be applied to the paper via the sealing tools for a much shorter time in order to achieve the optimum sealing temperature. Thanks to this shortened sealing time<\/strong> the high speed of 90 m\/min can be achieved.<\/p>\n

In order to protect the sensitive packaging material, the sealing profile and sealing jaws are matched to the paper material. Adjustable heating temperatures allow the process to be adapted to both the requirements of the packaging material and the Load capacity of the product to be packaged<\/strong> adapt. This prevents damage to the packaging material and product and both are processed particularly gently by the machine.<\/p>
