Common questions
What does ECT-48 mean, and why does it matter for my warehouse?
ECT (Edge Crush Test) measures horizontal crush strength. ECT-48 means the box wall resists 48 lbs of force per linear inch before failure. This rating ensures safe stacking of 3-4 pallet layers without box collapse, critical for warehouse density and freight efficiency.
How much weight can a single 18x12x12 double wall carton handle?
Double wall ECT-48 construction typically supports 65-85 lbs gross weight per carton depending on contents distribution and stacking configuration. Confirm exact load limits with product testing for your specific product density.
Will flat-shipped bundles reduce my warehouse receiving and storage costs?
Yes. Receiving flat bundles cuts inbound freight spend by 40-60% versus pre-assembled boxes. Flat storage requires minimal space until assembly, allowing just-in-time inventory practices that reduce overall packaging overhead.
Are these cartons compatible with automated packing lines?
Yes. Standard 18x12x12 dimensions integrate with most conveyor-fed automated packers. The kraft finish provides excellent grip for mechanical feeders without adhesion issues common with coated surfaces.
