You're packaging water pills, granules, or food powders into small sachets, and the output target is 60 pouches per minute. Can a single machine maintain that speed while delivering consistent fill weight and a fully sealed pouch? A Granular Packaging Machine with four-side sealing and volumetric cup filling is engineered for exactly this balance. The DXD-WL900E was designed around a four-side seal architecture that produces a fully enclosed pouch—sealed on all four edges—at speeds up to 60 times per minute. This article explains how the machine achieves that output, what four-side sealing means for pouch durability, and how the unit integrates into a complete production line.
Q: What sachet sizes and production speeds does the machine support?
A: Pouch length ranges from 50-120mm (adjustable), and pouch width ranges from 50-105mm. Production speed is up to 60 times per minute, depending on pouch size and material. Filling capacity ranges from 1-40ml.
Q: What film materials can the machine use?
A: The machine handles PET/AL/PE, PET/PE, NY/AL/PE, and NY/PE laminate films. Maximum film width is 900mm, with a maximum film diameter of Φ300mm and core diameter of Φ75mm.
Q: What does four-side sealing actually deliver?
A: Four-side sealing creates a sealed perimeter around the entire pouch. Unlike three-side seals, which leave one edge open, four-side seals provide a fully enclosed package with uniform edge strength. This reduces the risk of tearing or leakage during boxing, shipping, and handling.
Q: Is the machine suitable for pharmaceutical production?
A: Yes. The equipment fully complies with GMP production standards, making it suitable for pharmaceutical granules, water pills, and health products, as well as food and daily chemical applications.
Sachet integrity is tested not at the filling station, but downstream—when pouches are sorted, counted, boxed, and shipped. A three-side seal leaves an open edge where the film layers aren't bonded. That edge can catch on guides, tear during vibration, or allow moisture ingress. Four-side sealing closes that vulnerability. Every edge is heat-sealed, creating a symmetrical pouch with uniform strength in all directions. For products that require moisture protection—water pills, pharmaceutical granules, food powders—the fully sealed perimeter is a functional advantage, not just a cosmetic one. The DXD-WL900E's four-side sealing architecture is designed to deliver this integrity at production speed.
Water pills and granule products are hygroscopic—they absorb moisture from the air. A pouch with an open edge allows humidity to enter, degrading product quality. The four-side seal eliminates that pathway, providing a complete barrier that protects the product from filling through end use.
The machine is part of a larger production line that includes pouch sorting, up-opened cover box machines, and detection and rejection systems. Four-side sealed pouches feed more reliably into these downstream stations because their uniform edges resist jamming and misalignment.

The DXD-WL900E is not a standalone unit—it's the core packaging module in an integrated line that handles everything from filling to boxing:
The line performs automatic vacuum loading of granule material, then forms the sachets from roll film. The process is continuous and fully automated, requiring minimal operator intervention.
After filling and sealing, the machine prints batch numbers on each sachet and cuts tear notches for consumer convenience. These functions are integrated into the same production cycle.
The line includes an inspection and elimination machine that detects and rejects defective pouches before they proceed to boxing. This prevents non-conforming product from reaching the final package.
Finished sachets are automatically counted and stacked, then loaded into boxes along with instruction manuals. The boxing station (model SZH-60) handles box sizes from 85×37×40mm to 180×60×65mm at speeds of 20-60 boxes per minute.
Q: What products can be packed on this machine?
A: The machine is suitable for loose, non-sticky granular materials, including water pills, pharmaceutical granules, monosodium glutamate, sugar, salt, coffee, tea, desiccants, and seeds.
Q: How does the filling system ensure accuracy?
A: The machine uses a volumetric cup filling system. The measuring cup is adjustable within its specification range, allowing precise control of fill volume. The cup-type measurement ensures consistent fill weight across production runs.
Q: What maintenance does the machine require?
A: Routine maintenance includes checking seal temperature and pressure, inspecting the film feed path, and verifying the filling cup volume. The sealing system uses thermocouple sampling and digital temperature compensation for stable sealing quality.
Q: Can the machine be customized for different pouch sizes?
A: Yes. The manufacturer offers personalized design changes based on customer needs, including adjustments to pouch dimensions, film specifications, and line integration.
A Granular Packaging Machine with four-side sealing, 60 sachets/min speed, and GMP compliance is the practical choice for water pill, granule, and food sachet production. The DXD-WL900E delivers 50-120mm pouch length with 50-105mm width, 1-40ml filling capacity, PET/AL/PE, PET/PE, NY/AL/PE, and NY/PE film compatibility, and integration into complete production lines with automatic bag-opening, boxing, and detection systems.
Whether you're producing pharmaceutical water pills, food granules, or daily chemical sachets, this machine offers the sealing integrity and production efficiency that modern packaging operations demand. With a complete line covering vacuum loading through finished boxing, it reduces labor costs and production costs while maintaining GMP compliance.
