Square-bottom paper bag machine — the volume workhorse
The square-bottom paper bag machine is the most-sold format globally. It produces the classic SOS (Self-Opening Style) bag used by McDonald's, KFC, Subway, supermarket take-out counters, and major retailers. The machine takes paper roll input, prints (optional in-line), tubes the paper, gusses the sides, forms the square bottom with paste, and outputs finished bags ready for handle attachment.
| Specification | Standard machine | High-speed machine |
|---|---|---|
| Bag width range | 180-380 mm | 200-480 mm |
| Bag length range | 240-500 mm | 280-600 mm |
| Side gusset | 40-130 mm | 50-160 mm |
| Bottom width | 80-180 mm | 100-220 mm |
| Paper weight | 50-130 gsm | 50-150 gsm |
| Production speed | 80-130 bags/min | 140-220 bags/min |
| Daily output (8h shift) | 40,000-60,000 | 70,000-100,000 |
| Power | 15-22 kW | 22-35 kW |
| Machine weight | 4,500-6,500 kg | 6,500-9,500 kg |
| FOB price USD | 45,000-65,000 | 70,000-95,000 |
Total cost of production setup
A first-time paper bag converter setting up production needs more than just the bag machine. Plan capital deployment as follows for a basic SOS production line:
| Equipment / cost item | FOB China | Notes |
|---|---|---|
| Square-bottom paper bag machine (standard speed) | USD 45,000-65,000 | Main production unit |
| Handle attachment machine (flexo-loop) | USD 18,000-28,000 | Optional — only for handled bags |
| Flexo printing machine (4-color) | USD 30,000-55,000 | For printed shopping bags |
| Paper roll splitter / slitter rewinder | USD 12,000-22,000 | For converting jumbo rolls to machine-feed rolls |
| Air compressor (10-15 HP) | USD 1,800-3,500 | For pneumatics |
| Sea freight to most ports (40' container) | USD 3,500-7,500 | For full setup containerized |
| Import duty + clearance + inland transport | 10-25% of CIF | Varies by country |
| Installation engineer (factory dispatched) | USD 200-350/day + air + accommodation | Optional service |
| Subtotal — basic line | USD 75,000-150,000 | SOS bag machine + handle + air compressor |
| Subtotal — full line with print | USD 130,000-220,000 | Include flexo print + slitter |
Productivity economics — what the machine produces
Plan your business case with these throughput numbers as the upper bound. Real-world OEE (Overall Equipment Effectiveness) for paper bag production typically runs 65-78% — accounting for paper jams, glue station cleaning, roll changes, format changeover, and operator breaks.
Note: cost-per-bag above is machine amortization only over 5-year straight-line depreciation. It does NOT include paper, ink, glue, electricity, labour — these typically add USD 0.012-0.045 per bag depending on size and complexity. Total finished bag cost typically runs USD 0.02-0.08 ex-factory for SOS; USD 0.10-0.35 for printed luxury twisted-handle.
| Machine class | Theoretical max (8h) | Realistic OEE 70% | Annual output (260 days) | Cost per bag at full util. |
|---|---|---|---|---|
| Standard SOS (100 bags/min) | 48,000 bags | 33,600 bags | 8.7 million bags | USD 0.005-0.008 (machine amort.) |
| High-speed SOS (180 bags/min) | 86,000 bags | 60,000 bags | 15.6 million bags | USD 0.004-0.006 |
| Roll-fed pharmacy (300 bags/min) | 144,000 bags | 100,000 bags | 26 million bags | USD 0.001-0.002 |
| Twisted-handle luxury (50 bags/min) | 24,000 bags | 16,800 bags | 4.4 million bags | USD 0.015-0.025 |
Procurement checklist — separating manufacturers from traders
A real machinery manufacturer will: produce a video of your bag size on a similar machine within 3-5 days, send mechanical drawings and electrical schematics on request, take a 30% deposit / 70% balance against pre-shipment inspection, and welcome on-site factory visits with advance notice.
- Quote arrives within 30 minutes with rounded-number pricing — manufacturers need to engineer-quote each spec
- No video of YOUR specific bag size running on the machine — only generic factory tour video
- "Factory visit" arrangements are vague or always Sunday/holidays when nobody's there
- Machine model number doesn't appear on the supplier's website — only in the proforma invoice
- Cannot provide engineering drawings (mechanical, electrical, pneumatic) at sample inquiry stage
- Cannot provide the names of past customers in your region for reference checks
- Asks for >50% deposit with no LC option, no escrow — pure trust-me terms

Brand mentions: Brand references (McDonald's, KFC, Subway) are made for the sole purpose of describing the typical end-use of square-bottom paper bags in industrial discussions. SNDA Machinery is not authorized by, affiliated with, or endorsed by any of these brand owners and produces blank or buyer-branded paper bags only.
Pricing & specifications: All price ranges, output specifications, and lead-time figures reflect general market observation and may not apply to specific orders. Actual capital equipment pricing depends heavily on machine specification, paper grade compatibility, electrical configuration for buyer's grid, and freight terms.
Capital equipment caution: Paper bag machinery is capital equipment with 5-10 year service life and significant installation, training, and after-sales-service requirements. Buyers should perform on-site factory verification (or engage a third-party inspection service such as SGS, Bureau Veritas, or TÜV) before final payment. Plan installation, electrical commissioning, paper supply chain, operator training, and warranty service logistics as part of the total ownership cost.
No middleman role: CifyChina provides supplier discovery and editorial content. All transactions occur directly between buyer and supplier through the contact channels published on the supplier's official website.
