Detailed Guide: Explaining Features, Usage & Safety

Multi-Bag Style Versatility

Machines can produce multiple styles using interchangeable forming tubes.
Popular bag styles: pillow (basic), gusseted (side folds), flat-bottom (stand-up), quad seal (rigid), Doy pack (resealable, premium), brick (vacuum coffee), three- or four-side seal (sachets), and custom options with zippers/valves.

Integrated Filling Technologies

Weigh Fillers: For snacks, small pieces, hardware, pet treats.
Auger Fillers: For powders—flour, coffee, baking mixes.
Pump Fillers: For liquids, sauces, and semi-viscous products.
Each filling system can be integrated for automatic dispensing and consistent portion control.

Motion Type Breakdown

Intermittent Motion: Stops film for vertical and horizontal sealing before advancing. Best for moderate speeds, varied bag types, cost-effective, and lower skill requirement.
Continuous Motion: Film moves continuously; sealing/jaw mechanisms move in sync with film. Ideal for high output, larger operations, and for fragile products due to gentler handling.
