SJYB-IIISD Class 100 Back Seal Liquid Packaging Machine 134 Bags/Min

Class 100 Back Seal Liquid Packaging Machine SJYB-IIISD is a high-speed double-head fully automatic liquid pouch packing machine designed for hygienic liquid and semi-fluid packaging. It is suitable for pasteurized milk, yogurt drinks, soy milk, fruit juice, drinking water, plant-based beverages, protein drinks, sauces, soy sauce, active biological liquids, and similar products.

With a maximum speed of 134 bags/min, the SJYB-IIISD completes film feeding, UV sterilization, pouch forming, liquid metering, filling, back sealing, cutting, date coding, and finished pouch output in one automatic process. Its Class 100 clean purification system, PLC/HMI control, CIP-ready structure, and PE film compatibility make it suitable for clean, stable, and high-speed liquid pouch production.

Class 100 Back Seal Liquid Packaging Machine Overview

The SJYB-IIISD Class 100 Back Seal Liquid Packaging Machine is designed for packaging environments that require higher cleanliness and stable sealing quality. The back-seal pouch format is widely used for dairy, beverage, and liquid food products because it provides a reliable pouch structure and efficient forming process.

The machine uses a double-head filling structure to improve packaging efficiency while maintaining accurate metering and consistent pouch sealing. Its Class 100 clean laminar flow system helps protect the filling and packaging area during production.

4 Core Advantages of the Class 100 Back Seal Liquid Packaging Machine

1. Class 100 Cleanroom Packaging Protection

The machine can be equipped with a Class 100 clean laminar flow purification system above the forming and filling area. This helps create a cleaner packaging environment for dairy, beverage, and hygiene-sensitive liquid products.

2. High-Speed Double-Head Packaging

The double-head design improves production output by filling and sealing two pouches in each cycle. With production capacity up to 134 bags/min, the machine supports high-throughput liquid pouch packaging lines.

3. PLC Control and HMI Touchscreen Operation

The SJYB-IIISD uses PLC control and an HMI touchscreen for filling volume adjustment, speed setting, production monitoring, fault alarms, and recipe management. This makes operation easier and improves flexibility for different products.

4. UV Sterilization and CIP-Ready Cleaning

Strong UV sterilization treats the PE film before filling, while the CIP-ready liquid circuit supports automatic circulation cleaning. These features help improve hygiene and reduce manual cleaning work between production batches.

Applications

This Class 100 Back Seal Liquid Packaging Machine is suitable for hygienic packaging of liquid and semi-fluid products.

• Pasteurized milk, yogurt drinks, and dairy beverages
• Fruit juice, soy milk, drinking water, and plant-based beverages
• Protein drinks, cold noodle soup, and beverage bases
• Soy sauce, sauce products, and liquid condiments
• Active biological liquids and other hygiene-sensitive liquid products

Workflow

First, PE roll film enters the servo film feeding system and passes through UV sterilization. The machine forms the pouch, meters the product, fills through the double-head filling system, completes back sealing, cuts the pouch, prints the date code, and discharges the finished bag automatically.

The Class 100 clean purification system works during packaging to support a cleaner production environment. Operators can adjust packaging speed, filling volume, sealing settings, and production parameters through the HMI touchscreen.
