Plastic Bottle Syrup Oral Liquid Production Line: 5 Real Configs from 30 to 200 Bottles/Min September 8, 2026 — Haimen Yuanda Pharmaceutical Machinery Co., Ltd. We published the30-100 mL glass-bottle oral liquid line and the small-bottle (5-50 mL) essential oil line earlier this month. This article covers the third member of our oral liquid family: the plastic bottle syrup oral liquid production line. This line is built for plastic bottles (PET, PE), 30 to500 mL, used for syrup, oral solution, and tonic-style liquids. The 5-model data below is from our production records. 1. What this line is for - Bottle sizes: 30 mL, 50 mL, 100 mL, 150 mL, 200 mL, 250 mL, 500 mL - Bottle materials: PET (most common), PE - Common products: cough syrup, pediatric syrup, herbal tonic, vitamin oral solution, electrolyte drink, plant extract solution Full process: 1. Automatic bottle unscrambling 2. Gas washing (clean air purge to remove dust and particles) 3. Servo-driven filling station 4. Capping5. Aluminum foil sealing (heat induction) 6. Self-adhesive labeling The line runs as a complete linkage or as individual standalone machines. Built in line with current GMP requirements. 2. The 5-model spec table (all measured data, no estimates) | Model | Output (BPM) | Installed power | Power supply | |---|---|---|---| | YD-LSLP6/1 | 30-50 | 8.5 kW | 380 V / 60 Hz | | YD-LSLP8/2 | 60-80 | 10 kW | 380 V / 60 Hz | | YD-LSLP10/2 | 70-90 | 10 kW | 380 V / 60 Hz | | YD-LSLP12/10 | 100-150 | 12 kW | 380 V / 60 Hz | | YD-LSLP16/12 | 150-200 | 15 kW | 380 V / 60 Hz | All5 models share the same PLC control architecture (Siemens S7 series), the same HMI (10-inch color touchscreen), and the same filling station design. The differences are the number of filling heads, capping heads, and the conveyor length. 3. Why we use gas washing instead of water washing for plastic bottles Glass bottles can be washed with water and dried with hot air. Plastic bottles cannot. A wet plastic bottle surface leads to: - Label adhesion failure (the label peels off within 24 hours) - Static buildup during filling- Microbial growth in trapped moisture The solution is gas washing: a clean compressed air purge at the unscrambling-out stage. The air is typically0.6 MPa, filtered to 0.2 μm, and oil-free. Some customers ask if they can skip gas washing. The answer is: yes, if your upstream is is in a class D cleanroom with low particulate count. For most syrup producers, gas washing is the more reliable choice. 4. Why we use aluminum foil sealingPlastic bottles do not give the same tamper-evidence as a glass bottle with a flip-off cap. The solution industry standard is heat-induction aluminum foil sealing on the bottle mouth, under the cap. The foil seal: - Provides visible tamper evidence (broken seal = product was opened) - Extends shelf life by reducing oxygen ingress - Reduces leakage during transportThe foil sealer is integrated into the line between the capper and the labeler. Rejection is by induction: a foil that does not bond seal is is rejected by a downstream weight-check or vision system. 5. The PLC and HMI setup, in plain language The line uses: - Siemens S7 PLC (the workhorse of Chinese pharmaceutical machinery) - 10-inch color HMI, Chinese and English language - Two control modes: full PLC touchscreen control, or conventional relay control (for plants transitioning from older lines) Both modes are available on every model. Most customers choose the PLC touchscreen mode. 6. Sizing recommendation (field data, not theory) - Below 100,000 bottles / month: YD-LSLP6/1 - 100,000 to 250,000 bottles / month: YD-LSLP8/2 or YD-LSLP10/2 - 250,000 to 500,000 bottles / month: YD-LSLP12/10 - Above 500,000 bottles / month: YD-LSLP16/12 Calculated on 25 working days, 8 hours per shift, single shift. For 24/7 operation, multiply by 3. 7. What we need from you to give you a binding quote Four pieces of information. With these, we can size the right model and give you a binding price within 24 hours: - Bottles per month (target output) - Bottle size range (e.g. "100 mL to 250 mL") - Product type (cough syrup, herbal tonic, vitamin solution, or other) - Viscosity range (water-thin, medium, honey-like) If you do not have all four yet, that is fine. Send what you have. 8. Compliance, documentation, and after-sales - Built in line with current GMP requirements - Member of the China Pharmaceutical Equipment Industry Association - Documentation supplied before shipment (Chinese and English): - Operation manual, maintenance manual - Electrical drawings, pneumatic drawings - Complete BOM, coded spare parts list - PLC/HMI program backup (editable, with maintenance password) - Material certificates, PM plan - On-site installation, commissioning, operator training - Remote video support for 6 months after SAT 9.
