Laundry detergent packaging is shifting from bottles to pouches, yet many companies are hitting a bottleneck: the filling machine.
While flexible pouch packaging offers many advantages, it places new demands on filling equipment. Standard bottle-filling machines are unsuitable, and many general-purpose pouch-feeding machines on the market struggle with issues like unstable pouch feeding, stringing or dripping during filling, and insecure sealing when handling laundry detergent.
With 27 years of expertise in pouch packaging equipment, Qingdao Yilong has launched two machine types tailored to the laundry detergent industry—the Pouch-Feeding Packaging Machine and the Spout Pouch Filling & Capping Machine—precisely covering the needs of different pouch formats. This guide explains exactly which machine suits your pouch type and production capacity.
Pouch-Feeding Packaging Machine
Flat pouches / Stand-up pouches / Spout pouches (side-filling)
If you use flat pouches, stand-up pouches, or spout pouches filled from the side, the Yilong Pouch-Feeding Packaging Machine is the ideal solution.
Qingdao Yilong Pouch-Feeding Packaging Machine
Machine Structure: Single-lane or dual-lane options available
• Single-lane model: Compact footprint and quick changeover; ideal for small-to-medium batches or production lines with limited space.
• Dual-lane model: Parallel dual-station operation doubles production capacity; ideal for large-scale production.
Key Advantages:
✔ Automated pouch picking, opening, filling, and sealing in a seamless process
✔ Compatible with multiple pouch types; versatile multi-purpose machine
✔ Specially designed for side-filling spout pouches (no capping required)
Spout Pouch Filling & Capping Machine
Designed specifically for spout pouches (filling through the spout)
If your product is a standard spout pouch (screw-cap flexible packaging) and requires filling through the spout followed by automatic capping, the Yilong Spout Pouch Filling & Capping Machine is the right choice. Customizable configurations ranging from 2 to 24 heads
