3. Key Differences & Selection Recommendations

When recommending models to customers, guide them through three main criteria:

  1. Selection by Material State:
  2. Liquids (Water, Milk, Juice): Choose the Liquid VFFS Machine (SJ/SJZF series). Choose SJZF if graphic alignment or composite film is required.
  3. Pastes & Sauces (Ketchup, Shampoo, Honey): Choose the Paste VFFS Machine (PA series).
  4. Powders (Milk powder, Flour, Coffee): Choose the Powder VFFS Machine (P series) alongside an optional screw feeder.

  5. Granules (Nuts, Candies, Seeds): Choose the Granule VFFS Machine (G series), upgrading to a combination scale for strict weighing accuracy.

  6. Selection by Filling Range & Capacity:

  7. Small Sachets / Sample Packs (5ml-100ml or 5g-100g): Select compact entry models like Liquid SJ-1000/SJZF-1000, Paste PA100, Powder P100, or Granule G100.
  8. Large Pouches / Bulk Packaging (200ml-2000ml or 250g-5000g): Select heavy-duty industrial models like Liquid 2000 series, Paste PA500, Powder P500, or Granule G500.
