Plastic bag making machine YG-A series

heavy-dutyhigh-speed

Overview
Buying a plastic bag making machine requires assessing real output, material compatibility and sealing control rather than only initial price. The YG-A series offers multiple models to cover film widths from 100 mm to 1000 mm and speeds suitable for small runs up to mass output scenarios. Verify actual performance with your film type to determine total cost of ownership.

Key applications

• Construction projects: produce heavy-duty polythene bags, cement sacks and aggregate pouches that need high seam strength.
• Logistics & warehousing: manufacture courier envelopes, tamper-evident bags and padded mailers with fast cut-off and glue-strip options.
• Medical & food packaging: operate in controlled environments to produce waste liners, zipper bags and food wraps that meet hygiene requirements.

Performance comparison

• Output speed: Entry-level setups 50–100 pcs/min — Heavy industrial grade 150–300 pcs/min.
• Control system: Stepper motor + photo sensor (entry) — Full servo motors + inverter drives (industrial).
• Scrap rate: typically >3% on low-end units; <0.5% on tuned industrial systems.

Real-world considerations

• Prioritise full servo drives and accurate photo tracking for high-speed runs to reduce film scrap and improve sealing consistency.
• Test machine performance with your actual film samples (including recycled or biodegradable films) to confirm PID heat control and sealing behaviour.
• Fast-wear parts include cutting blades, Teflon tape, heating rods and rubber strips; schedule regular cleaning and lubrication to extend service life.
