Its compact design saves 30% floor space, making it perfect for supermarkets, retail chains, and packaging factories seeking high-efficiency, space-saving bag manufacturing solutions.Fast-Speed Double-Channel Bag Maker

Key Features


Dual-Track Synchronous Output System

The Double-Channel Bag Maker’s unique double-channel design integrates two parallel production tracks, operating synchronously to produce two batches of T-shirt bags at once. This innovative structure boosts output to 400 pcs/min, significantly exceeding the capacity of traditional single-channel machines. It maintains consistent quality across both channels, ensuring uniform bag size and sealing strength.


Full-Automatic Production Process

From film feeding, bottom sealing, and punching to cutting and stacking, the entire production process is fully automated. No manual operation is required, reducing labor costs and human errors. The servo motor-driven system ensures smooth coordination between each process, achieving continuous, uninterrupted production.


Photoelectric Sensor Positioning & Deviation Correction

Equipped with high-precision photoelectric sensors, the Bag Maker automatically aligns printing patterns on the film. It detects deviations in real time and performs auto-correction, ensuring that logos, texts, or patterns on finished bags are accurately positioned—critical for branded packaging.


Triple Auto-Protection Mechanism

The machine features intelligent protection against material absence, film breakage, and mechanical jamming. Once an abnormality is detected, it immediately stops operation and triggers an alarm, preventing equipment damage and reducing waste. This feature enhances operational safety and extends the machine’s service life.


Space-Saving & Compact Design

Optimized structural design reduces the machine’s footprint by 30% compared to conventional models. It can fit into limited workshop spaces without compromising production capacity, making it an ideal choice for small to medium-sized packaging facilities.
