Unmanned Smart Bag Production Line for 24/7 Continuous Operation

Our BIB bag making machine is engineered for precision and efficiency, delivering up to 18 bags per minute with a maximum bag width of 1300mm and length of 800mm (double format). Designed to handle all heat sealing materials, including pure PE, this high-performance heat sealing bag production line supports a film width of 1350mm and accommodates roll diameters up to 800mm. Its robust construction spans 20000mm x 4890mm x 2380mm and weighs 9 tons, ensuring industrial-grade stability and durability. Whether you're packaging liquids, semi-liquids, or paste-based products, this 24/7 continuous operation bag production line provides reliable, high-speed output with consistently strong sealing performance.

It is perfectly suited for producing packaging such as Tomato Sauce Bag-in-Box, Coffee Beans Bag-in-Box, Oil Bag-in-Box, and Milk Bag-in-Box.

Features

Firstly, it adopts high-precision ultrasonic device, which can accurately calculate the diameter of the roll. And, with the position calculation of the absolute value encoder of the floating roll, it ensures the consistent pressure of each roll of film. Secondly, the bag-making speed is adjustable, which can be flexibly changed according to the production demand to improve the operation performance. In addition, it is equipped with automatic film breakage detection and alarm function. Once film breakage is detected, an alarm can be issued in time to avoid production interruption. ML-1300BIB is suitable for producing BIB bag-in-box made of plastic film, composite material, and other single materials.

How to Choose the Right Bag-in-Box Bag Making Machine

Not all bag-making machines are created equal. If you're upgrading your packaging line or entering the BIB market for the first time, choosing the right BIB bag making machine is a critical decision that affects product quality, operational efficiency, and ROI.

1. Confirm Film Compatibility with Your Product Needs

The machine must be compatible with the laminated films or coextruded films used in your bags. Common structures include:

? PET/AL/PE, PET/NY/PE, or EVOH-based films

? High-barrier multilayer films for liquid food, wine, or industrial chemicals

? Biodegradable or recyclable films for sustainable packaging initiatives

Check if the machine can handle your film’s thickness, tension, and sealing temperature range reliably.

2. Define Your Bag Type and Structural Requirements

Bag-in-Box bags come in various formats. You’ll need a machine that can accurately produce:

? Single web center seal bags

? Side seal or bottom seal bags

? Bags with fitments (e.g., gland insertion or corner spout)

? Customized shapes or gussets

If you require fitment welding or punching (for spouts or dispensing valves), make sure the machine supports this process precisely.

3. Match Output Speed to Your Production Volume

Bag-making speed directly affects your throughput. Key factors include:

? Production capacity (bags/min or meters/min)

? Maximum film width (typically 800mm–1300mm)

? Maximum roll diameter and unwind type

A high-speed servo-driven machine is ideal for large-scale manufacturers, while a mid-speed semi-automatic model may suit smaller operations or contract packers.

4. Consider Automation and Control System Features

Modern BIB bag making machines often include:

? PLC + HMI touchscreen interface for easy operation

? Servo motors for precise cutting, sealing, and positioning

? Tension control and EPC (Edge Position Control) for stable film tracking

? Error detection and alarm systems

Advanced machines also support remote monitoring, batch counting, and memory settings for repeat jobs.

5. Evaluate Bag Size Flexibility

Check the maximum and minimum bag sizes the machine can produce:

? Bag length: Up to 400–600mm per double stroke

? Bag width: Often up to 600mm or more

? Adjustability: Is it tool-free? Can it quickly switch between sizes?

Flexibility is essential if you produce for multiple markets (e.g., 3L, 5L, 10L, 20L formats).

6. Ensure Fitment Compatibility

If your application involves filling valves, spouts, or dispensing glands, confirm:

? The machine includes or integrates with fitment insertion units

? It ensures precise alignment and leak-proof welding

? It’s compatible with your gland shape and position (center/top/corner)

For special applications (e.g., corner valve with cap), the fitment positioning mechanism should be fully programmable.

7. Prioritize Reliability and After-Sales Support

Your machine supplier should offer:

? Robust machine construction (e.g., stainless steel or aluminum alloy frames)

? Detailed operator training and documentation

? Spare parts availability

? Remote diagnostics or on-site support

Investing in a trusted brand may cost more upfront but saves time and downtime in the long run.

8. Think About Future Expansion

Will you add more filling lines or expand production capacity later? Choose a machine that:

? Is modular and easy to upgrade?

? Can be integrated with automatic filling, capping, or boxing lines

? Supports IoT or MES system integration for Industry 4.0 environments

By aligning these factors with the right technical configuration, you’ll secure a machine that delivers efficiency, quality, and long-term value.
