Doy-pack machine with weigher AF-500-D

The AF-500-D Doypack machine with a weigh filler is an automatic filling and packaging machine designed to dose and pack free-flowing and granular products into pre-made stand-up pouches. This model is designed for reliable industrial operation, producing neat, airtight, and commercially attractive packaging without the need to form bags from roll film.

The machine combines weigh-based dosing, pneumatic mechanisms, and automatic sealing, ensuring high filling accuracy, consistent results, and minimal operator intervention.

 

Suitable products for the AF-500-D

The AF-500-D model is ideally suited for packaging:

  • coffee beans and ground coffee

  • tea and herbal blends

  • grains (rice, buckwheat, millet)

  • sugar and salt

  • seeds, nuts, and dried fruits

  • granules and pet food

  • dragees, candies, and loose snacks

With the correct settings, the machine handles products of varying particle sizes and densities.

 

Packaging format

The AF-500-D is designed for use with pre-made Doypack bags, specifically:

  • stand-up pouches

  • Doypacks with zip-lock (open)

  • pouches without closures

This packaging format is convenient for storage, transport, and retail; it looks great on the shelf and enhances the product’s appeal to the end consumer.

 

Machine Operating Principle

The packaging process runs automatically:

  1. The machine picks up and opens a pre-made Doypack pouch

  2. The weigh filler accurately measures the preset product portion

  3. The product is fed directly into the pouch

  4. The pouch opening is aligned

  5. Hermetic heat sealing is performed

  6. The finished pouch is moved to the discharge area

Safety algorithms such as “no pouch — no filling” are implemented to reduce product waste and prevent operator errors.
