A vacuum packaging machine removes the air from the bag just before the seal closes. Less oxygen means slower spoilage and better product protection. This guide covers how the machine works, the two machine designs, and the applications where vacuum packaging is beneficial.<\/p>\n

How It Works in Four Steps<\/h2>\n
    \n
  1. The product is placed in a bag with ribbed panels so that air can escape from all sides.<\/li>\n
  2. The machine extracts the air\u2014from a room or through a nozzle.<\/li>\n
  3. The seal closes the bag leak-proof under negative pressure.<\/li>\n
  4. Optionally, the machine releases a protective gas (to modify the atmosphere) for fragile products.<\/li>\n<\/ol>\n

    Chamber machine or nozzle machine<\/h2>\n

    Aspect<\/th>\nChamber machine<\/th>\nNozzle machine (external suction)<\/th>\n<\/tr>\n<\/thead>\n
    Principle<\/td>\nThe bag is in a vacuum chamber<\/td>\nThe nozzle empties the bag on its own<\/td>\n<\/tr>\n
    Product Type<\/td>\nLiquids and pastes as well<\/td>\nOnly dry, solid products<\/td>\n<\/tr>\n
    Residual oxygen<\/td>\nTypical for under-21s (TP3T)<\/td>\nHigher, depending on the bag and product<\/td>\n<\/tr>\n
    Tempo<\/td>\n4 to 10 cycles per minute<\/td>\n1 to 3 bags per minute<\/td>\n<\/tr>\n
    Investment<\/td>\nHigher<\/td>\nBearing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n

    The chamber machine has the edge in terms of accuracy and speed; the nozzle is sufficient for small batches and simple products.<\/p>\n

    Five Applications<\/h2>\n
      \n
    1. Fresh meat and fish: inhibits bacterial growth and typically extends shelf life by a factor of 3 to 5.<\/li>\n
    2. Cheese and dairy products: help prevent drying out and mold growth.<\/li>\n
    3. Ground coffee: retains its aroma \u2014 see the coffee packaging machine<\/a> and instant coffee packaging machine<\/a> for the entire production line.<\/li>\n
    4. Industrial parts: protects against corrosion and moisture during transport and storage.<\/li>\n
    5. Medical and sterile supplies: Keeps the packaging free of contaminants until use.<\/li>\n<\/ol>\n

      Bags and plastic wrap<\/h2>\n

      Vacuum bags have a ribbed structure on at least one side and a barrier layer, typically a PA\/PE laminate. Parts that come into contact with the product are made of 304 stainless steel as standard in the food-grade version. For an overview of bags and bag-filling machines<\/a> Please read the separate guide.<\/p>\n

      Sustainability<\/h2>\n

      The biggest sustainability benefit of vacuum packaging isn't in the film but in the product itself: a longer shelf life means less waste. Also, use bags that are the right size\u2014bags that are too large waste film unnecessarily.<\/p>\n
