Grepack Completes 12-Head Laundry Detergent Filling Line for Poland 1L Bottles
2026-10-28
Grepack has completed a 12-head laundry detergent filling line for 1L bottles for a customer project in Poland. The connected system combines servo piston dosing, organized bottle conveying and preparation for downstream capping, labeling and coding, providing a practical production solution for household and personal care liquids.
A detergent bottling project designed around 1L containers
Laundry detergent presents several filling challenges, including viscosity changes, foaming and product stringing at the nozzle. Grepack developed the Poland line around the customer’s 1L bottle format and production requirements. Twelve filling heads support parallel dosing, while the servo piston filling system provides controlled volume adjustment for repeatable daily operation.
Anti-drip nozzle design, bottle positioning and coordinated conveyor movement help keep the filling area organized. The line can be configured according to the detergent formula, bottle neck, cap type and target output, allowing the equipment to work as part of a complete automatic detergent packaging system.
From bottle feeding to finished packaging
The filling machine can connect with an automatic bottle unscrambler, cap sorting and capping equipment, labeling, date coding, inspection, carton packing and finished-product collection. This modular structure gives producers the flexibility to automate one stage first or build a full laundry detergent bottling line from the beginning.
- 12-head servo piston filling: controlled multi-nozzle dosing for 1L detergent bottles.
- Stable conveyor handling: coordinated bottle transfer through filling and downstream stations.
- Formula-oriented configuration: options for foaming, viscosity and stringing characteristics.
- Complete-line integration: connection with capping, labeling, coding and packing modules.
Suitable for daily chemical products
In addition to laundry detergent, the system can be evaluated for liquid detergent, dishwashing liquid, liquid soap, fabric care products, shampoo and conditioner after sample testing. Filling range, product-contact materials and nozzle structure are selected according to the actual liquid and container.
For buyers comparing a liquid detergent filling machine or 1L bottle filling line, project engineering is important. Grepack reviews bottle samples, cap drawings, product viscosity, required accuracy, capacity targets and factory layout before confirming the final configuration.
