Core Winding / Tube Winding

Toilet paper cores, paper towel tubes, textile spools, film cores – they’re all made by spiral winding paper strips with adhesive between the layers. The bond needs to handle winding tension without the tube collapsing or the wall thickness varying.

Industrial cores for heavy film or wire need stronger adhesives than bathroom tissue cores. Food-grade convolute tubes (the seamless kind) have different requirements again. Tube labels are a separate application entirely – sticking information and branding onto finished tubes.

The adhesive bonds layers as they wind at speed and needs to set fast enough to maintain tension throughout the process. What gets wound onto the finished core affects adhesive choice – heavy film rolls put the core under considerable internal pressure. Structural integrity matters because core failure means wasted product and production downtime on the winding line.
