Non-Woven Bag Production Lines – Designed, Manufactured and Integrated for Real Production Needs
VietSonic develops each production line around the exact product the customer needs to manufacture, including fabric type, bag style, dimensions, weld positions, handle attachment method and target output.
VietSonic Delivers More Than a Machine – We Build a Complete Manufacturing Solution
A production line is truly effective only when the machinery, materials, bag design and operating procedures are engineered as one unified system. VietSonic therefore approaches every project from the customer’s actual manufacturing requirements instead of applying the same machine configuration to every factory.
Product Assessment
We analyze the bag sample, bottom structure, handles, material, fabric weight and load-bearing requirements.
Solution Engineering
We select the appropriate feeding, forming, edge-welding, cutting, punching and handle-attaching methods.
Manufacturing and Integration
Mechanical structures, electrical controls, drive systems and ultrasonic welding units are integrated into one synchronized production line.
Testing and Handover
The line is tested with actual materials, fine-tuned, demonstrated to operators and supported technically after handover.
A Production Line Engineered Around the Product You Intend to Manufacture
Different bag styles require different machine structures, tooling, fabric-folding methods and weld positions. VietSonic defines these factors from the beginning to prevent investment in equipment that cannot achieve the required bag design, production speed or seam strength.
- Engineered for the required bag width, length and fabric weight.
- Customized side-gusset, bottom-folding and bag-body forming mechanisms.
- Integration of ultrasonic edge welding, bottom welding or handle attachment.
- Adjustable material feeding speed and fabric-roll tension.
- Optional counters, sensors, speed controls and finished-product collection systems.
- A configuration matched to the available floor space and operating workforce.
Continuous Automation from Fabric Roll to Finished Bag
Depending on the bag style and required automation level, the processes can be connected into one continuous line or divided into separate modules for phased investment.
Fabric Roll Feeding
The fabric is stabilized and its tension controlled before entering the machine.
Folding and Forming
Guiding mechanisms form the bag body, side gussets or bottom according to the required bag design.
Ultrasonic Welding
Fabric edges are bonded quickly and cleanly without loose sewing threads.
Cutting and Finishing
The line cuts each product to the programmed length and finishes the handle or carrying-hole position.
Counting and Collection
Finished bags are counted according to the preset quantity for easier packaging and output control.
Flexible Solutions for Different Production Scales and Investment Goals
Businesses can choose a complete production line or individual machines based on current output requirements and future expansion plans.
Automatic Bag Production Line
Suitable for manufacturers requiring continuous operation, high output and consistent quality across production batches.
Semi-Automatic System
Combines a bag-body forming machine, handle-welding equipment and separate finishing processes, making future capacity upgrades easier.
Ultrasonic Welding and Handle-Attaching Machine
Performs handle welding, edge welding and seam bonding on non-woven fabric without sewing thread.
Custom-Built Equipment
Engineered for special bag samples, custom dimensions, factory layouts or integration with an existing production line.
Specifications Determined by Actual Manufacturing Requirements
The specifications below represent a reference configuration for a non-woven bag production machine. VietSonic adjusts dimensions, the ultrasonic system, operating speed and functional modules according to each manufacturer’s actual product sample.
- Multiple bag styles can be developed on the same system.
- Bag dimensions and production quantities are controlled through programmed settings.
- Reduces manual processes and dependence on operator skill.
- Allows convenient expansion with handle-attaching or product-finishing modules.
Final specifications are confirmed only after evaluating the material, bag design and required production capacity.
Manufacture a Wide Range of Non-Woven Bag Styles
From D-cut bags to gusseted bags and handled bags for advertising, retail, trade shows and product packaging.
D-Cut Non-Woven Bags
A compact, easy-to-use design suitable for stores, supermarkets, food products, trade shows and brand-promotion campaigns.
Bottom-Gusset and Side-Gusset Bags
The gusseted structure provides greater carrying capacity, a defined bag shape and suitability for a wide variety of products.
Real Manufacturing Capability Is Proven by Stable Production-Line Performance
VietSonic focuses on production performance after handover: the correct bag design, suitable weld quality, stable material feeding and equipment that operators can control effectively.
This is why every project must be evaluated using actual bag samples and production materials instead of selecting equipment solely from a generic specification sheet.
In-house evaluation of weld seams, materials and ultrasonic system configurations.
Custom structures, fixtures, guiding mechanisms and forming modules.
Synchronization of speed controls, sensors, drive systems and material feeding.
Operator training, maintenance guidance and technical troubleshooting support.
