5 Gallon PET Blow Molding Machine
5L / 10L / 20L — BPA-Free, Food Grade

Q: What is the output of a 5 gallon PET blow molding machine?

The Sailwin SW-F5L-2 produces up to 1,800 five-gallon jugs per hour with a 2-cavity configuration. The SW-F10L-2 produces 1,200 units/hour for 10L containers, and the SW-F20-1 produces 650 units/hour for 20L barrels.

Q: What is the difference between SW-F5L-2, SW-F10L-2, and SW-F20-1?

SW-F5L-2 is a 2-cavity machine for containers up to 6,000ml (5-gallon 18.9L jugs) at 1,800/hour. SW-F10L-2 handles larger 10,000ml containers at 1,200/hour. SW-F20-1 is a single-cavity machine for maximum 20,000ml barrels at 650/hour — the largest container in the range.

Q: Can the 5 gallon PET blow molding machine produce BPA-free bottles?

Yes. All containers produced on the Sailwin SW-F series are made from BPA-free food-grade PET material. PET is FDA and EU food contact approved and is actively replacing PC polycarbonate in markets worldwide due to health and regulatory requirements.

Q: What preform size does a 5 gallon PET blow molding machine use?

The SW-F5L-2 uses large preforms up to 200mm height with 48mm neck diameter. The SW-F20-1 requires preforms up to 240mm height with an 80mm neck diameter. Sailwin can advise on compatible preform suppliers for your target container format.

Q: Is the 5 gallon PET blow molding machine suitable for a water depot?

Yes. The SW-F5L-2 is specifically designed for water depot and water bottling plant applications. It produces 18.9L (5-gallon) reusable jugs at 1,800/hour, compatible with standard water depot filling, capping, and sanitising lines. Over 100 water plant customers globally use Sailwin machines.

Q: How much space does the 5 gallon PET blow molding machine require?

The SW-F5L-2 machine dimensions are 4.8×2.0×2.4m. The preform loader adds approximately 2×1.2×2.7m. Recommend a minimum floor area of 30m² for the machine plus material handling and output conveyor. Cleanroom or standard factory environments are both suitable.

Q: What voltage is available for the 5 gallon PET blow molding machine?

The voltage is customisable to match your local power supply requirements — 380V/50Hz, 415V/50Hz, 440V/60Hz or other specifications. Please confirm your local voltage when requesting a quotation so we can pre-configure the electrical panel correctly.

Q: What certifications and after-sales support does Sailwin provide?

All Sailwin 5-gallon PET blow molding machines are CE certified and undergo a full factory acceptance test before shipment. A 1-year warranty with remote technical support is standard. Engineers can also provide on-site installation and commissioning assistance worldwide. Spare parts are stocked and dispatched within 24 hours.

INFRARED HEATING SYSTEM

Rotary Infrared Heating — Built for 5-Gallon Preforms

Large-volume preforms for 5–20L containers require up to 3× more heating energy than standard bottle preforms. The SW-F large-volume series uses a rotary oven design with 4×10 to 4×12 infrared lamps, delivering 72–82kW of precise, zone-controlled heat to ensure uniform wall thickness on every jug.

BPA-FREE PET vs PC

Why Water Plants Are Switching from PC to PET 5-Gallon Bottles

PC (polycarbonate) has been the standard for reusable 5-gallon water jugs for decades. However, BPA-free PET is now replacing PC globally — lighter, clearer, and safer for consumer health.

* Reuse cycle advantage of PC is offset by BPA health and regulatory concerns in most markets.

Why Sailwin 5-gallon PET machines are sold in 60+ countries:

BPA regulations are tightening across the EU, North America and Southeast Asia. Water depot operators who invest now in PET jug blow molding capacity are positioned to serve both existing customers and new health-conscious markets — with lighter jugs that cost less per unit and meet all current food safety standards.

FAQ

5 Gallon PET Blow Molding Machine — FAQ

What is the output of a 5 gallon PET blow molding machine? ＋

The Sailwin SW-F5L-2 produces up to 1,800 five-gallon jugs per hour with a 2-cavity configuration — making it the highest-output model for standard 18.9L (5-gallon) water jugs in the SW-F range.

The SW-F10L-2 produces 1,200 units/hour for 10L containers, and the SW-F20-1 produces 650 units/hour for 20L barrels. Contact us to calculate your required model based on daily production targets.

What is the difference between SW-F5L-2, SW-F10L-2, and SW-F20-1? ＋

SW-F5L-2 is a 2-cavity machine for containers up to 6,000ml (standard 5-gallon / 18.9L jugs) at 1,800/hour with 65,000kg clamping force.

SW-F10L-2 handles 10,000ml containers at 1,200/hour with 80,000kg clamping force. SW-F20-1 is a single-cavity machine for maximum 20,000ml barrels at 650/hour — the largest in the range, with 280mm max diameter and 80mm neck.

Can the 5 gallon PET blow molding machine produce BPA-free bottles? ＋

Yes. All containers produced on the Sailwin SW-F series use BPA-free food-grade PET material. PET is FDA and EU food contact approved and is the fastest-growing replacement for PC polycarbonate in the 5-gallon water jug market.

Furthermore, BPA-free PET jugs are approximately 30% lighter than equivalent PC jugs, reducing transport costs and improving handling ergonomics for depot operators.

What preform size does a 5 gallon PET blow molding machine use? ＋

The SW-F5L-2 uses preforms up to 200mm height with a 48mm neck diameter. The SW-F20-1 requires preforms up to 240mm height with an 80mm neck diameter — significantly larger than standard bottle preforms.

In addition, the rotary heating oven is specifically calibrated for large-body preforms. Sailwin can advise on compatible preform suppliers in your region as part of the order support process.

Is the 5 gallon PET blow molding machine suitable for a water depot? ＋

Yes. The SW-F5L-2 is purpose-designed for water depot and bottling plant applications. It produces 18.9L (5-gallon) reusable jugs compatible with standard depot filling, capping, and sanitising lines. The output conveyor can be integrated directly with your filling system.

Sailwin machines are currently operating in water bottling plants across Southeast Asia, the Middle East, Africa and Latin America. Contact us to discuss your depot's specific output requirements and available floor space.

How much space does the 5 gallon PET blow molding machine require? ＋

The SW-F5L-2 main machine footprint is 4.8×2.0×2.4m. The preform loader adds approximately 2×1.2×2.7m alongside the machine. A minimum floor area of 30m² is recommended to accommodate the machine, preform hopper, and output conveyor with safe operator access.

Both cleanroom and standard factory environments are suitable. Specifically, the SW-F series is commonly installed in ISO Class 7–8 cleanroom water bottling facilities in the Middle East and Southeast Asia.

What voltage is available for the 5 gallon PET blow molding machine? ＋

The voltage is fully customisable — 380V/50Hz (China standard), 415V/50Hz (Europe/Asia), 440V/60Hz (Americas) or other local specifications. The electrical panel is pre-configured at the factory to match your region before shipment.

Please confirm your local voltage and frequency when requesting a quotation. Installed power consumption is 82kW (SW-F5L-2) — confirm your facility's power supply capacity before ordering.

What certifications and after-sales support does Sailwin provide? ＋

All Sailwin 5 gallon PET blow molding machines are CE certified and pass a full factory acceptance test — running your specific jug format at full production speed — before shipment. Factory video is provided for remote inspection.

A 1-year full warranty with remote technical support via video call is standard. Engineers are also available for on-site installation and commissioning worldwide. Spare parts stocked in factory, dispatched within 24 hours of request.
