How does the machine handle cutting for different bag types?

It allows seamless switching between cold-cutting (for laminated bags) and hot-cutting (for non-laminated bags) in under 1 minute. Hot cutting seals edges without adhesion, while cold cutting provides clean, fray-resistant edges.

What is the warranty period for the machine?

We provide a 1-year warranty for the machine, along with lifetime after-sales service and lifelong technical support.
