Automatic Multi-line Powder Back-sealed Bag Packing Machine

Parallel Processing Efficiency

By operating 2–6 lines simultaneously, the machine reduces production time by up to 60% compared to single-line alternatives. Each line features independent sensors and error detection, ensuring a single line malfunction doesn’t halt the entire production. The coordinated servo system maintains ±0.5% filling accuracy across all lines, even when handling varying powder densities—from lightweight flour (0.5g/cm³) to dense talcum powder (1.2g/cm³).

Dust Containment System

Integrated with a HEPA 13 filtration unit (99.97% particle capture rate for ≥0.3μm particles) and negative pressure filling chamber, it minimizes airborne dust to protect operators and prevent cross-contamination. The self-cleaning filter triggers automatic purging every 2 hours, reducing maintenance downtime by 40% compared to manual cleaning systems.

Tool-Free Changeover

Quick-release augers and modular sealing bars enable product switchovers in 15–20 minutes. The PLC stores up to 20 product recipes, each saving parameters for auger speed, sealing temperature (120–180℃), and bag length (80–250mm). This flexibility suits businesses producing multiple powder products, from spice blends to pharmaceutical excipients.

This machine excels in industries requiring high-volume powder packaging with strict hygiene standards:

• Food & Beverage: Milk powder, coffee granules, baking mixes, sugar, and powdered drink mixes (with anti-caking agent compatibility).

• Nutraceuticals: Protein powders, collagen supplements, and dietary fiber blends (using BPA-free contact parts).

• Chemicals: Detergent powders, industrial additives, and pesticide formulations (with corrosion-resistant components).

• Pharmaceuticals: Medicinal powders, herbal extracts, and antibiotic granules (compliant with GMP standards).

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: What bag materials are compatible with back sealing?

A: It works with heat-sealable films including PE, PET/PE laminates, and paper-plastic composites (thickness 0.08–0.15mm). The adjustable sealing pressure (0.3–0.6MPa) ensures secure bonds even with textured or matte finishes.

Q: How does it handle cohesive powders that tend to clump?

A: The anti-clog hopper features a vibratory base (30–60Hz frequency) and Teflon coating to break up clumps. For highly cohesive materials like brown sugar, an optional hopper heating jacket (30–50℃) reduces moisture-induced sticking.

Q: What is the power requirement for multi-line operation?

A: It operates on 380V three-phase power (50/60Hz) with a maximum consumption of 4.5kW. An optional voltage stabilizer is available for regions with power fluctuations ±15%.
