Performance and Features

Our advanced 3-line vest handle T-shirt bag making machine is the ultimate solution for high-volume packaging manufacturers looking to optimize efficiency.

Triple Output, Single Footprint: The 3-lane independent layout allows you to produce up to 840 bags per minute in total, drastically cutting down energy consumption and labor costs per bag compared to standard single-line machines.
Patented Eco-Friendly Sealing: Features an exclusive patented hot-cutting and synchronous sealing system optimized for both standard poly films and tricky biodegradable materials (PLA+PBAT), ensuring zero tearing or weak bottom seals.
Independent Tension & Alignment: Each lane operates with its own precision micro-tracking system and auto-tension controls, allowing stable feeding even if the film rolls vary slightly in quality.
Smart "Rocking" Anti-Stick System: The heavy-duty collection pile integrates an automated rocking system that prevents fresh hot-sealed bag bottoms from sticking together during high-speed stacking.
All-in-One Inline Automation: Fully automated process from triple-roll unwinding, photo-cell color mark tracking, pneumatic auto-punching, to final counting and folding with automatic waste film trim collection.
Global Multi-Language HMI: User-friendly PLC touch-screen operating system with built-in support for English, Spanish, Arabic, Russian, Turkish, and Chinese.
