In Vertical Form Fill Seal (VFFS) packaging, the \u0424\u043e\u0440\u043c\u043e\u0432\u0449\u0438\u043a \u043c\u0435\u0448\u043a\u043e\u0432<\/b> <\/a>(also known as the “Trunk” or “Collar”) is responsible for turning a flat roll of film into a perfect tube. If the geometry is off by even a millimeter, you face constant downtime due to film breakage, wrinkles, or misaligned back-seals.<\/p>\n

2. Why “Off-the-Shelf” Formers Often Fail<\/b><\/h4>\n

Many manufacturers try to use generic formers. However, different films (PE, Laminates, Paper) have different friction coefficients.<\/p>\n

    Surface Coating:<\/b> For sticky or thin films, our formers feature premium coatings (like Teflon or sand-blasted finishes) to reduce drag and prevent “static” build-up.<\/p>\n<\/li>\n<\/ul>\n

    3. Customization: The Key to Flexibility<\/b><\/h4>\n

    When you launch a new product size, you don’t need a new machine\u2014you need a precision-engineered bag former.<\/p>\n

      \n

      Square Bottom vs. Pillow Bag:<\/b> We design formers specifically for your bag style to ensure the “ears” are tucked perfectly.<\/p>\n<\/li>\n

    • \n

      Gas Flushing & Dust Suction:<\/b> Our formers can be integrated with gas nitrogen injection tubes for freshness or dust extraction ports for powdery products.<\/p>\n<\/li>\n<\/ul>\n

      <\/p>\n

       <\/p>\n

      4. Maintenance Tip: Protecting Your Former<\/b><\/h4>\n

      A small scratch on the shoulder of the former can ruin thousands of bags.<\/p>\n

        \n
      • \n

        Daily Check:<\/b> Always clean the collar with a non-abrasive cloth to remove adhesive residue or dust.<\/p>\n<\/li>\n

      • \n

        Storage:<\/b> When switching sizes, store your formers on a dedicated rack to avoid denting the precision edges.<\/p>\n<\/li>\n<\/ul>\n
