Equipment summary
Selection summary
This CO2/UV laser coding band sealer combines continuous heat sealing with date and batch marking at a reference conveyor speed of 25 m/min and 0-300 °C temperature control.
Product Description
The machine continuously conveys and seals bags while applying production dates, batch codes or traceability information. CO2 and UV lasers interact differently with materials, so contrast, clarity and heat effect must be tested on the actual film.
Provide the bag structure, marking area, character or QR-code size, target speed and power supply. The machine and sample image are from page 16 of the 2026 Yigao catalog.

FAQ
How do I choose between CO2 and UV laser?
Test the actual packaging material for absorption, contrast, heat sensitivity and required marking quality.
Can laser coding damage the bag?
Incorrect power, speed or focus can burn through or embrittle the material, so validate both mark quality and package integrity.
