Why Four-Side Seal?

Maximizing Product Integrity & Shelf Life

Four-side seal packaging is widely recognized as the premium standard for single-dose and portion-controlled products. By sealing all four edges of the pouch, this format provides superior barrier protection, precise dosage control, and a perfectly flat, highly printable surface area.

Hermetic Barrier Protection

Sealing all four sides ensures absolute protection against moisture, oxygen, and light. This is critical for sensitive pharmaceutical powders, active chemical compounds, and perishable food ingredients.

High-Speed Multi-Lane Efficiency

Our machines utilize multi-lane vertical configurations, allowing for simultaneous production across 4 to 20 lanes. This increases production output up to 1,200 sachets per minute while minimizing floor space.

Precise Dosing & Filling

Equipped with advanced servo-driven augers, volumetric cups, or liquid piston pumps, our machines ensure highly accurate dosing, minimizing product waste and ensuring strict compliance with weight regulations.

Got Questions?

Frequently Asked Questions

1. What materials are suitable for four-side seal packaging?

Four-side seal sachets are suitable for a wide range of materials, including fine powders (flour, protein, medicine), granules (sugar, coffee, silica), liquids (cosmetic serums, lubricants), and viscous pastes (sauces, gels).

2. Can I adjust the sachet size on a multi-lane machine?

Yes. Sachet length can be easily adjusted via the HMI touchscreen (PLC). Sachet width requires changing the forming tube/sealing jaw assembly, which is designed for quick changeover to minimize downtime.

3. How does Ludyway guarantee dosage accuracy?

We use high-precision dosing systems tailored to the product. For powders, servo-driven augers provide exact rotation counts. For liquids, rotary valve piston pumps deliver precise volume metrics with no-drip functions.

4. Do your machines support nitrogen flushing?

Yes. We integrate nitrogen flushing systems to displace oxygen inside the sachet prior to sealing, significantly extending the shelf life of food and pharmaceutical products.
