One packet, many products: from sugar to active ingredients<\/h2>\n

A sachet is a flat, single-serving pouch made of heat-sealed film for small quantities\u2014typically ranging from 1 to 50 grams or milliliters. Sugar sticks in caf\u00e9s, spice portions in restaurants, shampoo samples in magazines, effervescent powder in pharmacies: the same principle applies everywhere. The sachet machine produces these pouches in a continuous process\u2014by design, it is a Vertical filling and capping machine<\/a>, designed for narrow formats and tight sealing tolerances. The machine base corresponds to the classic vertical form-fill-seal machine<\/a>; what distinguishes sachet machines are their format range, number of lanes, and dosing accuracy at low fill volumes.<\/p>\n

Production Process: From a Roll of Film to a Finished Sachet<\/h2>\n

The machine operates according to the VFFS principle in five stations:<\/p>\n

    \n
  1. Film unwinding:<\/strong> The film roll (typically 200 to 600 mm wide) is unwound with controlled web tension; a photocell reads registration marks to ensure that the printed image is positioned precisely within the sealing window.<\/li>\n
  2. Molded part:<\/strong> Forming shoulders and folding blocks transform the flat web into a tube. In 4-side sealing, additional metal plates fold the side edges before the longitudinal seam\u2014this creates the characteristic angular sachets.<\/li>\n
  3. Longitudinal and transverse sealing:<\/strong> Heated sealing jaws close the longitudinal seam, followed by the top and bottom cross seams. The sealing area is small\u2014which is why the tolerances for temperature, pressure, and time are tighter than for larger bag sizes.<\/li>\n
  4. Dosage:<\/strong> Above the filling tube, the dosing station dispenses the product into the open hose\u2014the choice of method depends on the product being filled (see below).<\/li>\n
  5. Separation:<\/strong> A cross-cutting blade cuts between the seams; the finished sachet falls onto a conveyor belt or into a collection chute.<\/li>\n<\/ol>\n

    The Three Basic Formats<\/h2>\n\n\n\n\n\n\n\n

    The Stickpack is the narrowest sachet format\u2014manufactured on the Stitch-sewing packaging machine<\/a>, often with 4 to 10 lanes running in parallel. Multi-lane operation is the key to sachet production: A single-lane system produces 40 to 80 sachets per minute, while a four-lane stick-pack line produces four times that amount or more\u2014with the same machine length.<\/p>\n

    Dosing Method: It Depends on the Product<\/h2>\n
