Products Description
Light Grey Balance Paper is a dedicated back‑side balancing substrate for wood‑based panels, used in conjunction with surface decorative paper. It adopts a scientific blend of long and short fibers, added with low‑shrinkage stabilizers, moisture‑resistant additives and tension‑balancing formula. Produced via intelligent papermaking, constant‑temperature maturation and tension correction processes, it balances stress on both sides of panels and counteracts tension from the decorative top layer. Fundamentally solving panel defects such as warping, bending, arching and deformation, it serves as an essential supporting material for flooring, cabinet panels and fire‑retardant boards.

Production Line
Light Grey Balance Paper is manufactured on the intelligent special decorative base‑paper production line of Lunan New Materials. The whole workflow covers fiber pulp preparation, additive mixing & screening, Fourdrinier sheet forming, multi‑stage pressing, constant‑temperature drying, online tension correction, constant‑temperature maturation and calendering. Online visual inspection eliminates paper defects before rewinding and slitting into finished rolls. Closed‑loop monitoring system real‑time controls basis weight, moisture and shrinkage indicators. Special process adjustments are implemented targeting core tension‑stability performance of balance paper. Strict control over fiber proportion and additive dosage guarantees uniform shrinkage performance across batches, adapting to large‑scale industrial high‑speed impregnation and hot‑pressing for both domestic and overseas orders.
Packaging & Shipping
Finished large rolls of Light Grey Balance Paper are fully wrapped with heavy‑duty kraft paper. High‑strength paper edge protectors are installed at both ends to prevent end‑face bumping and chipping. Each roll is affixed with a separate shipping mark clearly indicating product name, basis weight, width, batch number and net weight. Rolls are pallet‑stacked and fully secured by stretch film. Special moisture‑absorbing bags are placed inside sea‑going containers. Spacer boards are arranged between rolls to avoid friction‑caused damage and end‑face dampness during transit. Rolls of different basis weights and batches are stacked separately for convenient receiving and warehouse management.
After-Sales Service
1.Complete factory test reports covering core indicators including shrinkage rate, dry‑&‑wet tensile strength and moisture content are delivered with each shipment.
2.Quality objections regarding base paper shall be raised within 7 working days upon goods receipt. Submission of real‑roll photos, videos and hot‑pressing process records is required for rapid technical verification.
3.Sample rolls are available before mass production. Customers may conduct impregnation and hot‑pressing trials on local production lines to verify compatibility with panels and resin before bulk order execution.
4.Professional technical support team provides online guidance. Suitable basis weight of balance paper can be recommended according to panel thickness and parameters of surface decorative paper to optimize hot‑pressing solutions.
FAQ
Q1: How to select proper basis weight for Light Grey Balance Paper corresponding to panel thickness?
A: 70‑80 g/m² for thin panels of 6‑8 mm; 90‑100 g/m² for regular 12‑18 mm furniture cabinet panels; 100‑120 g/m² for HDF thick boards and laminate flooring. Stress matching with surface decorative paper basis weight shall also be considered.
Q2: Panels still warp after using balance paper. Is balance paper definitely the cause?
A: Panel warping results from multiple factors. Apart from balance paper performance, influencing factors include substrate quality, impregnation‑weight difference between front & back sides, hot‑press temperature, pressure, duration as well as warehouse ambient humidity. Full process parameters are required for joint root‑cause analysis.
Q3: Can Light Grey Balance Paper be used as surface decorative paper?
A: Not recommended. Light Grey Balance Paper is functionally designed for stress balancing without decorative surface finishing. It is only applicable for non‑visible back sides of panels.
Q4: Is FSC‑CoC certified supply available?
A: Yes. Relevant FSC‑CoC forest‑certification documents can be provided for export orders to meet procurement requirements for overseas green building materials.
