Common questions
What does ECT-48 mean and why does it matter for my warehouse?
ECT (Edge Crush Test) rating of 48 lbs/inch indicates the sheet's compression strength per linear inch of edge. ECT-48 kraft corrugated supports heavier vertical stacking loads, reducing product damage claims and enabling taller, more space-efficient pallet configurations in your warehouse.
Can I use these 30x30 sheets for all pallet sizes?
These sheets work best for standard 40 x 48" pallets where they provide full or partial deck coverage. They're ideal for creating interlayer separation on 40 x 40" and custom pallet configurations. Confirm your pallet dimensions to optimize coverage and stacking performance.
How many layers can I safely stack with ECT-48 double wall sheets?
Stack height depends on product weight, pallet type, and warehouse ceiling height. ECT-48 rated sheets safely support 4-6 product layers (40-60 lbs per layer) under standard conditions. Consult load calculators or your logistics team for application-specific stacking limits.
Are these sheets suitable for temperature-sensitive or humid environments?
Kraft double wall corrugated provides good moisture resistance for standard warehouse conditions. For high-humidity or refrigerated environments, consider sealed or wax-coated variants. Contact our sales team to discuss your specific storage conditions and product protection needs.
