Label core size and roll specification

Quick answer

This guide is for checking label rolls for a new labeller. Label rolls need to match the applicator unwind, sensor and peel plate configuration; otherwise even a good machine can suffer label feed faults.

It is most useful for new label applicator heads, wrap-around labellers and print and apply systems. The aim is to make the enquiry clearer before quotation, reduce the risk of under-specified equipment and help buyers compare labelling machine options on practical production details.

Specification checks

Before choosing a machine, collect the details that affect label presentation, product control and line uptime. These checks help decide whether the best route is a semi-automatic labeller, compact automatic system, inline applicator, print-and-apply unit or a fully integrated labelling line.

• core diameter and roll outside diameter
• web width compared with label width
• gap or black mark sensing requirements
• material stiffness and adhesive behaviour
• roll winding quality and splice control

Project details to confirm

The correct labelling route should be judged against real products and real labels. Small differences in container shape, label material, label gap, product stability or line speed can change the applicator head, product handling and acceptance test requirements.

For more accurate advice, send pack photos, label roll details, target output, current bottleneck and any drawings or videos of the existing line. Lancing UK can then help identify the most practical labelling route before a formal quotation is prepared.
