Low Thermal Expansion Stable Label Core

Low thermal expansion adhesive label cores optimize paper layer ratio and curing craft with ultra-low expansion coefficient under high-temperature die-cutting and drying workshop environments, avoiding tube diameter enlargement and roll wandering caused by continuous equipment heating, perfectly matching automatic label lines with drying and hot stamping procedures. Dimensions remain stable without deformation during long high-temperature continuous production. Balanced multi-layer winding eliminates thermal expansion and shrinkage difference to maintain consistent roundness permanently. Segmented constant-temperature drying rooms control tube internal stress with 3,000 tons annual capacity. We one-stop support 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. Heat-resistant chemical fiber cores keep shape during spooling in hot textile works…
