Automatic Multi-lane Powder Four-side Sealing Packing Machine

Micro-Dosing Precision

Each lane features an independent micro-auger system (diameter 6–12mm) optimized for small-dose applications. The dual-stage filling (80% coarse, 20% fine) minimizes overfill, crucial for high-value products like medicinal powders and nutraceutical supplements.

Four-Side Seal Integrity

The machine’s servo-controlled sealing jaws apply uniform pressure (0.2–0.4MPa) and temperature (140–190℃), creating hermetic seals that extend shelf life by preventing moisture ingress. This design is particularly effective for hygroscopic powders like baking soda and vitamin blends.

Flexible Format Options

It supports bag sizes from 30x50mm to 100x150mm and can produce stick packs, flat sachets, or gusseted pouches with minimal tooling changes. The optional perforation system creates easy-tear edges, enhancing consumer convenience for on-the-go products.

Perfect for single-serve and small-batch powder packaging across sectors:

• Food Service: Instant coffee, sugar sachets, spice blends, and powdered soup mixes (with flavor-specific lane isolation).

• Pharmaceuticals: Medicinal powders, effervescent drink mixes, and herbal supplement sachets (GMP-compliant).

• Personal Care: Face mask powders, bath salts, and foot soak crystals (with moisture barrier packaging).

• Household: Detergent pods, water treatment tablets, and dishwasher salt packets (water-soluble film compatible).

The operation of the machine is not done once and for all, and it is necessary to pay special attention to the state of the machine during each packaging process. In order to effectively manage and maintain the packaging machine and control the product quality, in addition to regular maintenance, the auxiliary personnel and feeding personnel of the equipment also need to follow the following operating procedures.

1. Turn on the power switch.

2. Check whether the air pressure is sufficient (must reach the standard requirements).

3. Click the host to start, and check whether each action is working properly.

4. Check and clean up each box room.

5. Put the bag, load the material, put the material box.

6. Click the host to start.

7. The product that is packaged in vacuum for the first time should be checked whether the seal is firm, whether the suction is tight and through the water check(Must check vacuum chamber 1-10).

8. During the production process, check the product sealing and pumping conditions continuously.

9. Every 2 hours after the machine runs, must be the top cover of the machine, bag clip, and funnel mouth, carried out with an air gun clean.

10. The bag or material dropped on the machine, should be hooked out with a hook, do not take it by hand.

Q: How does it prevent cross-contamination between lanes?

A: Each lane has dedicated augers, hoppers, and sealing jaws with physical barriers to prevent powder migration. Quick-detach components allow thorough cleaning between products, and optional UV sterilization further reduces microbial risk.

Q: What film materials work best for four-side sealing?

A: Optimal results with laminate films (PET/PE, NY/PE) and aluminum foil composites (thickness 0.07–0.12mm). The machine’s sealers adjust automatically for different materials using pre-stored film profiles.

Q: Can it print expiration dates or batch codes?

A: Yes, an integrated thermal transfer printer (300DPI) can print alphanumeric codes, logos, and QR codes on each bag. Print position is adjustable via PLC, ensuring alignment even with varying bag sizes.
