Heat sealing offers a wide range of advantages. In addition to creating a strong, tight seal that is often airtight and watertight, heat sealing can be used for a variety of products and materials. Heat sealing is a proven technology in the packaging industry, particularly in food packaging, medical products, and all kinds of industrial products, such as electronic devices and components. The packaging process can be carried out optimally and automatically, ensuring safe and reliable packaging.
In heat sealing, the packaging film is sealed shut by a seal. This process typically takes place on heat-sealing machines or sealing machines. The sealing machine heats the contact surfaces of the films to a specific temperature, which depends on the film material used. While the film is being heated, pressure is simultaneously applied to the contact surfaces. This causes the heated plastic layers to fuse together, creating a stable weld that reliably seals the film.
Choosing the right material is crucial when using heat sealing, because the film’s properties must be optimally matched to the melting point of the film, the product to be packaged and its characteristics, as well as the requirements for the packaging film. This, combined with the correct settings on the corresponding sealing machine, yields optimal packaging results, even at very high cycle rates.
We at Schlichter GmbH offer a comprehensive range of packaging machines that enable the production of high-quality heat-sealed packaging—whether automatically, semi-automatic , or manually.
Our wide selection of packaging films in the field of recycling and eco-friendly films, polyolefin fine-shrink films and BOPPfilms offers the right film for every purpose. We’d be happy to provide you with personalized advice tailored to your specific needs.
