Bag Unfolding Machine Details
Our Plastic Film Unfolding Machine (Plastic Bag Open Machine) is a compact and efficient solution designed especially for producing oversized single-layer plastic films.
When your extruder width is not sufficient, there’s no need to invest in an expensive new extruder. This machine opens double-layer film into a single layer, effectively doubling the usable width (e.g., 1.5 m → 3 m).
It handles the film unfolding and rewinding process automatically with high precision, ensuring balance, speed, and quality in production.
This system serves as an intermediate, cost-effective solution and can be easily integrated into Bag-on-Roll production lines to meet flexible manufacturing needs.
Bag Unfolding Machine Specifications
Equipped with a magnetic brake and load-cell support, the unwinder operates with a PID-controlled tension system.
Film tension is continuously monitored and stabilized, preventing material tears and winding errors.
Film edges are precisely detected using an ultrasonic fork sensor.
Thanks to the PID-controlled edge guiding module, winding accuracy and overall product quality are significantly improved.
Reducer-supported banana rollers play a critical role in ensuring smooth film unwinding and preventing wrinkles.
Main rollers controlled by an AC drive enable adjustable production speed and product sizing.
When the film runs out, the end-of-material sensor is activated and automatically stops the system.
It ensures operational safety and saves time.
During machine start/stop operations and emergency situations, visual alerts (warning lights) and audible alerts (buzzer) are activated.
This helps prevent operator errors and ensures a safe working environment.
Production outputs are recorded on a daily, weekly, monthly, and yearly basis.
This facilitates cost tracking, performance evaluation, and efficiency analysis for the operation.
- Rewinder, powered by a torque-controlled motor driver and supported by a load cell, ensures smooth and accurate winding at the desired tension.
- Tension imbalances that may occur during winding are automatically compensated to maintain stability.
Who should buy it?
- Companies producing oversized bags
- Manufacturers looking to reduce investment costs
- Factories needing intermediate processing before or after the extrusion line
Film Unfolding Machine or Film Open Machine
Global Solutions for Flexible Packaging Industry
A film Open machine (also known as a plastic film unfolding machine) is designed to convert double-layer plastic film into a single-layer wide film, effectively doubling the usable width without requiring additional extrusion capacity.
This solution is widely used by manufacturers in North America, Canada, Western Europe, and South America, where production efficiency, flexibility, and cost optimization are critical for staying competitive in the flexible packaging industry.
Increase Your Production Capacity Without New Extrusion Investment
With a film opening machine, manufacturers can significantly expand their production capabilities using their existing equipment.
For example:
A 1,600 mm double-layer film can be opened into a 3,200 mm single-layer film, allowing producers to manufacture wider products without investing in a new wide extrusion line.
This makes the film opening machine a high ROI solution for companies looking to scale efficiently.
The system works by:
- Feeding double-layer (folded) film into the machine
- Carefully separating the layers
- Converting it into a single-layer wide film
- Maintaining precise tension control throughout the process
- Delivering a stable and wrinkle-free output for downstream operations
This ensures high-quality film processing without deformation or instability.
Ideal for Global Manufacturers
Film opening machines are widely used in:
- USA & Canada – high efficiency and cost-driven production environments
