What is the difference between cored and coreless rolling?

Cored rolling uses cardboard cores for rigid, shelf-ready rolls – ideal for retail. Coreless rolling eliminates cardboard cores – saving material cost and enabling 24/7 automatic roll change without stopping production.

Does the coreless model support non-stop roll change?

Yes. Our patented coreless automatic roll change system enables 24/7 continuous production – automatically detecting full rolls, cutting, and starting new rolls without any operator intervention.

What is the perforation quality?

Our servo-driven perforation system provides consistent perforation depth (0.005-0.025mm digitally adjustable) – bags tear cleanly without chain breaks or tearing across bags.

Can the machine handle both cored and coreless configurations?

Yes. The machine handles both cored and coreless rolling configurations – one machine, two production modes for maximum flexibility.

What is the roll diameter?

Standard models produce rolls up to 300mm diameter. Custom sizes are available for specific retail or industrial requirements.
