Faster Lines and Heavier Reels Push Core Specification Upward
Film, label and nonwoven converting lines now run at speeds near 1,200 metres a minute on reels considerably heavier than the equipment of a decade ago carried. Both changes load the core harder: radial compression rises with reel weight and dynamic deflection matters more as speed increases. Standard spiral-wound cores that performed adequately at slower speeds now fail intermittently, which is worse than failing consistently because nobody attributes it correctly. High-strength precision-wound cores compound at 6.9% against a market at 4.6% on exactly this shift. Reel diameter increases compound the effect further.
Market Impact: Cores at 1.4% of reel value
