Choosing a paper bag making machine is part engineering, part economics. Let’s break it down step by step.
1. Bag types you need
Square-bottom (SOS) bags are great for shopping. Flat-bottom V-cut bags are simpler and cheaper. Twisted-handle bags command higher margins.
2. GSM range
Confirm the paper GSM range — most machines handle 60–150 GSM. Heavier bags need stronger forming tools.
3. Output target
Calculate your monthly demand. A 120 bags/min machine running 8 hours = ~58,000 bags/day. Match the machine to your sales pipeline, not your dream.
4. Servo vs mechanical
Servo drives cost more upfront but give you 15-20% better speed control and far less paper wastage. Worth the premium if you run two shifts.
