Project Background & Customer Profile
GRANTEK is a leading, technology-driven manufacturer in Eastern Europe specializing in the automated production of advanced granular chemical formulations. Equipped with a dedicated state-of-the-art formulation laboratory, the company develops customized drain-unclogging granules tailored specifically to regional piping infrastructures and water quality standards. Their products efficiently dissolve hair, grease, and tough obstructions without compromising pipe integrity.
Operating a robust cross-border supply chain, GRANTEK provides flexible OEM/ODM services through two distinct partnership models: standardized finished products and bespoke chemical formulations. They have established a stellar reputation as a highly reliable contract manufacturing partner for overseas household cleaning and chemical brands, thanks to their precision granulation technology and consistent high-volume delivery capabilities.
The Technical Challenges in Chemical Packaging
Packaging chemical drain opener granules presents strict environmental and mechanical challenges. GRANTEK required a packaging system capable of handling 0.5g to 2g granules that are inherently hygroscopic, highly corrosive, and prone to static accumulation.
During their production assessment, three critical pain points emerged:
Airborne Dust & Seal Contamination: The packaging process easily generates airborne chemical dust. If this dust drifts into the sealing jaws, it contaminates the sealing area, directly causing bag leakage, poor seal aesthetics, or product degradation.
Moisture-Induced Clumping: Due to the highly hygroscopic nature of the granules, any prolonged exposure to ambient humidity causes immediate clumping, severely impacting dosing accuracy and accelerating mechanical wear.
Corrosive Degradation: The chemical formulation reacts strongly with standard metals, requiring extreme material durability for all contact parts to ensure long-term equipment lifespan.

Vicanpack Custom Engineering Solution
To overcome the combined threats of corrosion, dust, and humidity, Vicanpack deployed the LDFS-720G 2-lane multilane sachet packaging machine integrated with a QVC-2 vacuum feeder. This customized system features targeted engineering upgrades:
1. Advanced Dust Contamination Control & Seal Integrity
Anti-Static Device: Specially engineered for chemical powders and fine granules. It neutralizes static electricity built up during high-speed film transport and material discharging. This prevents granule adhesion to the packaging film, eliminates film jamming, and ensures a pristine sealing zone.
Active Dust Extraction Tubes: Dual micro-vacuum extraction tubes are integrated directly onto both sides of the discharge chute. They actively capture airborne particles right at the dosing point before they can migrate to the sealing jaws, guaranteeing a 100% secure, leak-proof thermal seal.
2. Smart Moisture Protection & Process Optimization
Sealed Material Hopper: A completely enclosed hopper isolates the moisture-sensitive chemical granules from ambient warehouse humidity, keeping the material free-flowing.
Rapid-Cycle Enclosure (Optional): An engineered protective enclosure shortens the air exposure window from material transfer to final sealing.
Operational Best Practice: To maintain peak weighing precision and eliminate chemical moisture absorption over down-times, Vicanpack recommends clearing residual materials via a quick-purge cycle after each production shift rather than storing active chemicals in the hopper overnight.
3. Anti-Corrosion Configuration
316 Stainless Steel + Teflon Treatment: All mechanical components coming into direct contact with the chemical granules are upgraded to premium 316 Stainless Steel, reinforced with an industrial Teflon surface coating to maximize resistance against acid/alkaline corrosion and friction wear.
Customer Review & Proven Results
"We have been running Vicanpack’s automatic 4-side seal sachet packaging machine for over three months now, and the system performance has exceeded our expectations. It consistently clocks speeds of 55–60 sachets per minute while holding an incredible weighing accuracy within ±1g—well above our original technical brief."
"The combination of the sealed hopper and active dust extraction channels completely manages our airborne dust issues. Meanwhile, the anti-static kit keeps our sealing jaws perfectly clean. The touchscreen interface is highly intuitive, and the embossing coder delivers crisp, permanent batch stamps on our aluminum-composite laminate film. The technical training and rapid after-sales support from the Vicanpack team have been exemplary!"
