Products Description
Grey core paper is a cost-effective industrial special core paper refined from high-quality recycled fibers. It features compact and uniform texture, outstanding stiffness and strong support performance, with excellent light-proof effect to avoid light transmission and color leakage of coils. With stable toughness and great processability, it adapts to high-speed tube rolling and slitting with low loss and regular forming. Moisture-proof, storable and eco-friendly, it is widely used for industrial roll cores of films, tapes, non-woven fabrics and general paper tubes, serving as an economical and preferred base material for mass production.

Production Line
This professional grey core paper production line is tailored for recycled fiber processing with full automatic integrated procedures, equipped with multi-stage impurity removal, pulp homogenization and constant temperature closed-loop systems. It optimizes paper quality via fine fiber carding and pulp homogenization to control batch deviation. Featuring high automation, low energy consumption and stable operation, it supports efficient continuous mass production of various specifications, ensuring flat and uniform paper quality and stable large-scale supply.

Packaging&Shipping
Grey core paper is individually packaged with professional hard paper tubes. Each paper roll is fully inserted into the tube and fixed with adhesive tape to prevent loosening and offset during transportation. Equipped with external dust-proof and moisture-proof protection, it effectively isolates moisture aand dust to avoid paper damage and deformation. Finished products are sorted and stacked neatly with clear labels of batch and specification. Adopting standardized closed logistics transportation with regulated loading and stacking, it adapts to short and long-distance delivery, ensuring intact product delivery and supporting on-time bulk shipment.

FAQ
Q1: What are the core differences between grey, yellow and white core paper? A1: Grey core paper is made of high-quality recycled fibers, featuring high cost performance and stable light-proof performance for general paper tube production. Yellow and white core paper mostly adopt new pulp, suitable for high-end scenarios with higher cost.
Q2: Is the light-proof performance stable? Will it transmit light or shadow? A2: The paper features uniform color and stable light-blocking ability with no local light transmission or shadow penetration, effectively avoiding color and light leakage defects of film and tape rolls.
Q3: Does recycled grey core paper have poor stability? A3: Processed through multi-stage impurity removal and pulp homogenization, it has uniform fiber distribution, stable stiffness and controllable moisture content. It is not easy to soften or deform with tiny batch quality difference.
Q4: Can special grammage and width specifications be customized? A4: Full-spec customization is supported. We can customize core paper of different grammages and widths to adapt to customers’ tube rolling equipment and production needs.
Application Scenarios
Featuring stable stiffness, reliable light-proof performance and high cost performance, grey core paper is widely used for general industrial roll core production. It is mainly applied to paper cores for adhesive tapes, plastic film rolls, non-woven fabric rolls, textile auxiliary paper tubes and ordinary packaging hollow paper cylinders. Suitable for light industry, packaging consumables and textile industries, it adapts to conventional rolling, supporting and shaping working conditions, and perfectly meets the needs of large-scale and high-frequency industrial production.
