Buying Guide
Linerboard Supplier Guide for Corrugated Plants
Buyer guide to linerboard from China for corrugated plants: grades, GSM, strength, moisture, kraft vs recycled, converting fit, and RFQ specs for sheet and board producers.
Quick answer
Source linerboard by locking grade family, GSM, strength targets, and whether you need kraft, white-top, or recycled liners for print—then qualify mills on moisture and runnability. Liner choice sets ECT potential before starch chemistry is tuned.
Grade decisions
Kraft liners for strength/appearance; recycled testliner for cost; white-top for print panels. Mixing liners across seasons without re-qualification causes warp and bond issues.
Specs that belong on the RFQ
GSM, width, moisture band, burst/ring crush or plant-preferred strength metrics, shade for white-tops, and reel packing. Ask for mill certificates with lots.
Corrugator fit
Share target flutes and speeds. High-speed lines punish dusty or highly variable moisture reels. Trial reels beat brochure tables.
