Automatic Laundry Detergent Pod Production with PVA Film
The ZONESUN ZS-FRS100 automatic laundry detergent pod making machine forms, fills and seals water-soluble PVA/PVOH film to produce individually dosed detergent capsules. Its rotary system combines vacuum film forming, ceramic piston filling, top-film covering, sealing and automatic demolding in one continuous process, with an output of up to 40 pods per minute.
Designed for laundry detergent manufacturers and household cleaning product production, the machine supports customized pod shapes through replaceable molds. Actual output and filling performance depend on the formulation, pod design, film and operating conditions.
Key Features
- Integrated rotary production: Electronically synchronized cam control coordinates film forming, filling, covering, sealing and automatic pod discharge.
- Ceramic piston dosing: Wear-resistant ceramic pistons provide consistent liquid dosing, with a specified filling accuracy of ±0.1 g.
- PLC touchscreen operation: Adjust filling parameters and production speed, and monitor machine operation using the Chinese/English touchscreen.
- PID film tension control: Automatic film-feed adjustment helps reduce stretching, wrinkles and film breakage during production.
- Vacuum forming molds: Independent vacuum adsorption holds the bottom film in each mold cavity. Modular molds support different pod designs and approximately 30-minute mold changeover.
- Automatic covering, sealing and demolding: The machine applies top PVA film, seals the filled pods and releases finished pods onto the discharge conveyor.
Production Process
Bottom PVA Film Feeding → Vacuum Film Forming → Ceramic Piston Filling → Top PVA Film Covering → Film Sealing → Finished Pod Discharge

Applications and Configuration
Suitable for compatible liquid laundry detergents and cleaning liquids in water-soluble unit-dose packaging. Powder, granule and multi-compartment applications require confirmation of the appropriate feeding configuration, mold design and formulation compatibility before ordering. Sample pod designs shown in the images illustrate possible customized applications.
Electrical and installation requirements: Select the correct three-phase power supply. This industrial machine requires a suitable three-phase electrical connection and compressed air at 0.5–0.8 MPa. Confirm your local supply, formulation, target pod weight, film and mold requirements with ZONESUN before production.
