Common questions
What is ECT-32 and why does it matter for my warehouse?
ECT (Edge Crush Test) 32 measures the corrugated material's vertical stacking strength, rated at 32 lbs per linear inch. This standard-strength rating is ideal for typical industrial shipping where boxes stack 3 - 5 high without heavy loads, balancing durability with cost efficiency.
How much weight can these 21x14x14 boxes safely hold?
ECT-32 single-wall boxes typically support 20 - 30 lbs per box depending on product weight distribution and stacking height. For precise load calculations, consult Packrift's strength charts or contact our B2B support team with your specific product weight and stack requirements.
Will bulk ordering this size improve my freight efficiency?
Yes. The 21 x 14 x 14" dimension optimizes pallet utilization and cube efficiency for typical mid-sized products, reducing wasted space in shipping containers. Bulk ordering also locks in per-unit pricing, lowering your packaging costs and freight expenses over annual volume.
Are these boxes printed or can I customize them for branding?
These boxes ship blank kraft with no printing. Packrift offers custom printing, flexographic options, and pre-printed inventory for branded boxes; contact our sales team for quotes and minimum order requirements on customized versions.
