The unique VSM® Vacuum System was developed by our founder Sebastian Mayer back in the 1970s and is still fitted to all of our vacuum packaging machines to this day. With the VSM® System, air is evacuated using special suction hoses in the bag itself. The entire evacuation process is performed under ordinary atmospheric pressure – without a vacuum chamber. This guarantees a high-quality seal, while also protecting the structure. Evacuating air directly from the bag under ambient atmospheric pressure produces a number of unique advantages when it comes to product quality, leak-proofing, handling and resource efficiency.
