Common questions
What does ECT-32 mean and how does it perform?
ECT-32 represents Edge Crush Test rating of 32 lbs per inch, standard single-wall strength suitable for typical industrial shipping. This rating supports stacking loads up to 25-30 lbs per box in warehouse conditions, making it ideal for most B2B fulfillment operations without overengineering costs.
How many boxes per pallet and what are freight implications?
Flat-packed bundles of 25 achieve approximately 60-70 bundles per pallet (1,500-1,750 boxes), maximizing freight efficiency. Compared to rigid pre-assembled boxes, flat-packing reduces dimensional weight charges by 70-80%, directly lowering your per-unit shipping costs.
Is kraft material compliant with food and pharmaceutical shipping?
ECT-32 kraft corrugated meets standard shipping compliance for non-hazardous goods. For food contact or regulated pharmaceutical applications, we recommend consulting our packaging specialist to confirm specific FDA or industry certifications required.
What volume discounts apply and can I customize orders?
Volume pricing unlocks at 50+ bundles (1,250+ boxes). Custom printing, reinforced bottoms, and interior partitions are available. Contact our sales team for case-quantity pricing and design modifications tailored to your fulfillment requirements.
