Large Inner Diameter Heavy Label Master Roll Core

Large‑inner‑diameter heavy‑duty adhesive label cores are built for big‑diameter master‑roll production in large‑scale label factories. Thickened reinforced tube walls support hundreds‑of‑kilograms‑weight single sticker master rolls, resisting flattening and eccentric deformation after long static storage and fitting large‑size spindles of heavy‑duty rewinding and slitting machines. Multiple calibration procedures guarantee tube straightness and roundness for smooth master‑roll rotation, reduce machine vibration in high‑speed slitting, and improve equipment safety and label finished‑product yield. Jinan Fuyuan is equipped with extended large‑diameter winding machinery in its 3 900 ㎡ plant and delivers 3 000 tons annual output. We one‑stop produce cash register paper tubes, adhesive label paper tubes, chemical‑fiber industrial paper tubes, paper‑making industrial paper tubes, film industrial paper tubes and printing industrial paper tubes for large‑size label groups and industrial‑roll‑…
