Vacuum sealers operate differently from vacuum chambers in that the bags are placed externally to the machine rather than inside it. Air is then removed and the bag is sealed. It is useful for these processes to occur outside of the machine when products need to be vacuum packed in a certain way and the operator, therefore, needs to survey the pack as it is being processed. The Magvac power sealer is a validated, heavy-duty stainless-steel vacuum sealer that is food safe and hence, suitable for a wide range of products including consumables and pharmaceuticals. It has been built according to the latest directives and is industrial grade due to the efficiency of its operation. Used in both vacuum packaging and modified atmosphere packaging, a validated machine means that the same temperature and pressure is applied each time a product is sealed for consistency.
