The General Guide to Snack Packaging Machines<\/a> covers the entire field; this page focuses on the vertical line showing weight and nitrogen \u2014 the arrangement behind family-size bags of chips, bags of nuts, and popcorn<\/a>.<\/p>\n

The three-part structure<\/h2>\n
    \n
  1. Doser: multihead weigher.<\/strong> Brose snacks require a multi-head weigher<\/a> with a gentle approach, low drop heights, and heads with small angles of fall\u2014the same principles as in granules<\/a>, but more critical because every tear is visible in the bag.<\/li>\n
  2. Bag maker: VFFS.<\/strong> The vertical form, fill, and seal machine makes the bag from a roll of film, using a larger bag circumference than for powdered products because production volumes remain low.<\/li>\n
  3. Nitrogen flushing.<\/strong> A flow of nitrogen in the bag displaces oxygen and cushions the fall: a cushioning effect for fragile products. When properly adjusted, the residual oxygen level remains below 2%.<\/li>\n<\/ol>\n

    Why Nitrogen Is an Essential Part of It<\/h2>\n

    Nitrogen serves two purposes at once: the bag acts as a cushion to protect the crumbs, and the oxygen that causes rancidity is removed. For chips<\/a> and notes<\/a> That's the difference between a bag that crinkles and a bag that hangs limp and rancid on the shelf.<\/p>\n

    Film and Barrier<\/h2>\n

    Snack film combines a barrier against oxygen, moisture, and light with a thickness of 50 to 80 \u00b5m. Metal layers or EVOH barriers extend shelf life; recyclable mono-PE versions can be discussed on a project-by-project basis. Weigh the choice of film against the shelf-life requirements\u2014see also film consumption<\/a>.<\/p>\n

    Speed and Accuracy<\/h2>\n

    Light doses between 10 and 150 g can be processed at a rate of approximately 100 bags per minute using a 14-head weigher, with a dosing accuracy of around \u00b10.5 g. Heavier family-size bags slow the rate down to 30 to 60 bags per minute.<\/p>\n

    When Snacks Should Not Be Packaged in a VFFS<\/h2>\n

    Molded products\u2014bars, cookies, chocolates\u2014lose their shape when dropped and belong on a flow packer<\/a>. The rule of thumb remains: if it falls and can withstand the fall, use a VFFS; if it lies flat and needs to stay that way, use a flow packer.<\/p>\n

    Frequently Asked Questions<\/h2>\n

    Q: Do you package chips using a VFFS or a flow packer?<\/strong><\/p>\n

    Both are common. Small retail bags of baked chips are often packaged horizontally; family-size bags and individually weighed bags are packaged on the VFFS with nitrogen.<\/p>\n

    Q: What are the benefits of nitrogen flushing?<\/strong><\/p>\n

    Less oxygen\u2014below 2% when properly adjusted\u2014and a cushion that absorbs the impact. This translates to a longer shelf life and less crumbling.<\/p>\n

    Q: Which scale is used for small doses?<\/strong><\/p>\n

    A multihead weigher with 14 heads and small weighing pans; it achieves high speeds for doses up to approximately 150 g.<\/p>\n
