Protein powder packing machine

Advanced Moisture-Proof Doypack Packaging with Nitrogen Flushing & Spoon Insertion

Protein powder is a highly hygroscopic substance, which means it easily absorbs moisture from the air. Improper packaging can lead to clumping, oxidation, and reduced shelf life. To combat these challenges, our automatic rotary doypack packing machine provides a specialized solution tailored for sensitive powders like protein powder, milk powder, and infant formula.

By using high-barrier packaging materials such as aluminum foil composite bags and PET/PE laminates, the machine ensures excellent protection against moisture and oxygen, while also enhancing puncture resistance to safeguard product integrity during transportation.

Additionally, protein powder packaging often includes a measuring spoon inside the pouch. Our system supports this feature with a customized vibration feeder, tailored to the exact size and shape of the spoon, making the process seamless and fully automated.

✅ Nitrogen Flushing System

To extend product freshness and prevent oxidation, the machine is equipped with a nitrogen flushing system. This function displaces oxygen from the pouch before sealing, helping preserve nutrients and avoid clumping caused by moisture.
