Common questions
What is the ECT rating and how does it impact box performance?
ECT-32 indicates Edge Crush Test of 32 lbs per linear inch, industry standard for general-purpose shipping. This rating supports 2-3 box stacking in transit and handles typical warehouse handling without collapse or product damage.
How many boxes can I stack on a standard pallet without exceeding weight limits?
The 18x16x14 footprint allows approximately 40-45 boxes per pallet layer (3 layers deep). Actual stacking height depends on product weight and warehouse ceiling clearance. Most facilities safely stack 6-8 bundles high.
Is this box suitable for heavy products or fragile items?
ECT-32 single-wall is optimized for products up to 25 lbs. For heavier items or fragile goods, consider ECT-44 double-wall alternatives. Interior void fill and bubble wrap are recommended for breakables.
Can these boxes be customized with branding or printing?
Yes, bulk custom printing is available at higher volumes. Contact our sales team for volume pricing and minimum order requirements for branded kraft boxes.
