Compact Non Woven Box Bag Making Machine: Medium-Speed Flexible Conversion
A compact non woven box bag making machine is an engineered converting line designed specifically for regional converters, contract packagers, and manufacturing facilities where plant floor space and electrical infrastructure are constrained. Operating at a stable velocity of 60 to 80 bags per minute, mid-tier platforms like the OYANG 16S and SMART 19 compress the entire converting footprint into less than 9.5 meters in total line length. This economical box bag machine architecture enables dual-mode conversion between 3D box bags and standard 2D flat bags while lowering capital equipment investment by 35% to 45%.

Why Floor Space and Flexible Batch Sizing Dictate Machine Selection
While heavy-duty mega-lines like the 100 BPM TECH series dominate ultra-high-volume commodity grocery supply chains, small-to-medium packaging enterprises face a different set of day-to-day manufacturing realities:
Restricted Plant Bay Dimensions
Standard industrial box bag lines measure 13.5 to 15 meters long, requiring expansive column spans. A small footprint non woven bag machine measures under 9.5 meters, fitting comfortably into standard 12-meter factory bays with ample clearance for pallet transit.
Electrical Grid Limitations
Mega-scale converting cells often require 35 to 50 kW of connected load, requiring costly substation transformer upgrades. A medium speed box bag machine operates at 18 to 22 kW total connected load, readily compatible with standard industrial workshop feeds.
Multi-Product Order Profiles
Regional suppliers cannot survive on 3D shopping totes alone. They frequently produce flat boutique carry bags, take-out carrier pouches, and D-cut bags. Compact machines offer rapid mechanical reconfigurability between 3D box and 2D flat formats.
Engineering Benchmark: Compact Platform vs Flagship Converting Mega-Line
Selecting the appropriate machinery tier requires balancing speed targets against floor space, changeover frequency, and capital budget:
| Evaluation Parameter | OYANG 16S / SMART 19 (Compact Platform) | OYANG TECH 23 (Flagship Industrial Cell) |
|---|---|---|
| Rated Converting Velocity | 60 – 80 bags/min (Continuous) | 90 – 100 bags/min (Continuous) |
| Overall Machine Footprint (L×W×H) | 8,800 × 2,100 × 2,200 mm (<9.5m total) | 13,200 × 2,400 × 2,400 mm |
| Total Connected Power | 18 – 22 kW (Low energy draw) | 32 – 40 kW (High-speed multi-axis) |
| Dual-Mode Capability | Full Support (3D Box Bag + 2D Flat Bag) | Optimized Primarily for 3D Box Bags |
| Format Mold Change Mechanism | Guided Manual / Semi-Power Adjusted (15–20 min) | 90-Second Motorized Auto Change |
| Capital Outlay (CAPEX Tier) | Economical Entry / Mid Tier | High-End Industrial Infrastructure |
| Ideal Factory Shift Volume | 30,000 – 45,000 bags/shift | 65,000 – 85,000 bags/shift |
Dual-Mode Kinematics: Transitioning Between 3D Box and 2D Flat Bags
A critical competitive advantage of an economical box bag machine is mechanical adaptability. Packaging operations can accept diverse contracts by reconfiguring the web transport line:
1. 3D Box Bag Production Mode
In box bag mode, the continuous non-woven web passes through the secondary triangle folding station and mechanical gusset-tucking fingers. The pneumatic bottom-forming mold engages, pressing the side and bottom creases while dual 20 kHz ultrasonic horns seal the 3D corners. Simultaneously, the inline loop handle station cuts, rotates, and fuses the soft handles onto the interior bag rim.
2. 2D Flat Bag & D-Cut Transition Mode
When client demand shifts to high-volume flat merchandise bags, the operator disengages the triangle bottom expanders and bypasses the 3D creasing assembly through the touchscreen HMI. The machine feeds the web directly into transverse ultrasonic seamers and an integrated hydraulic die-cut module, producing clean, flat D-cut bags or flat loop-handle carrier bags without installing separate converting equipment.
Structural Integrity: Japanese MAZAK & OKUMA CNC Processing
Economical machinery should never compromise on structural rigidity. When a 60 80 pcs min bag machine operates 16 hours a day, mechanical vibration from unbalanced frames causes ultrasonic horn misalignment, resulting in weak or scorched seams.

Like OYANG’s flagship mega-lines, every OYANG 16S bag machine and SMART 19 non woven machine chassis is precision-machined on Japanese MAZAK and OKUMA 5-axis CNC machining centers. Holding wallboard parallelism and bearing seat concentricity within ≤ 0.015 mm guarantees smooth web tracking, minimal ultrasonic horn wear, and a structural operational service life exceeding 12 years.

What is a compact non woven box bag making machine?
A compact non woven box bag making machine is a space-saving industrial converting system designed with a total line length under 9.5 meters, engineered to produce three-dimensional non-woven carrier bags at medium speeds between 60 and 80 bags per minute while occupying minimal floor space.
What is the production speed of the OYANG 16S bag machine?
The OYANG 16S bag machine operates at a verified production speed of 60 to 80 bags per minute for standard 3D box bag formats, yielding approximately 30,000 to 45,000 finished bags per 10-hour working shift.
Can a compact box bag machine produce flat bags as well as 3D box bags?
Yes, compact converting platforms like the OYANG 16S and SMART 19 feature dual-mode mechanical setups that allow operators to switch between 3D box bags with side gussets and 2D flat bags or D-cut bags on the same production line.
How much electrical power does an economical box bag machine require?
An economical box bag machine such as the OYANG 16S typically requires a total connected electrical power capacity of 18 to 22 kW, allowing it to operate efficiently on standard industrial utility feeds without requiring high-capacity electrical transformer upgrades.
How much floor space is required to install an OYANG 16S or SMART 19 line?
The core machine dimensions for an OYANG 16S are approximately 8.8 meters long by 2.1 meters wide. Including working clearances for roll loading, pallet stacking, and operator walkways, an installation space of roughly 12 meters by 4 meters (about 50 square meters) is recommended.
