Why quality shipping boxes matter
Damaged orders cost time, money and trust. A carton specified to the load cuts returns and keeps your support queue clear.
Right-sizing does two jobs. It removes void fill, and it lowers dimensional weight, which is what carriers bill on: cubic inches divided by a divisor, commonly 139 for UPS and FedEx domestic daily rates and 166 for some USPS services. Two inches off a box height across 5,000 units is a real line on your freight invoice.
Crisp print and tidy edges then carry the brand from warehouse to doorstep.
Durable shipping boxes: features you can count on
Strength and protection
Board strength is measured two ways. Edge Crush Test measures stacking strength, and 32 ECT is the standard single wall grade, with 44 and 48 ECT for double wall. Mullen burst measures puncture resistance, with 200 lb test single wall and 275 lb double wall as common equivalents. Every corrugated box carries a Box Maker’s Certificate stamp showing its rating, maximum gross weight and size limit.
Choose single wall in E flute at 1.5mm, B flute at 3mm or C flute at 4mm for standard goods, and BC double wall around 7mm for heavy items, long routes or pallet stacking.
One thing most suppliers skip: corrugated loses much of its compression strength in high humidity, so boxes stored or shipped in damp conditions need a moisture-resistant coating or a step up in grade. Tell us the route and we factor it in.
Precision die-cuts, reinforced seams and reliable adhesives keep boxes stacking straight and sealing tight. Edge guards and inserts are available, and we build to ISTA 3A or ASTM D4169 where a retailer requires transit evidence.
Sustainability
Recycled content and curbside recyclable board are standard, alongside FSC certified stock, PCR content and soy based inks.
Corrugated is one of the few strong sustainability stories in packaging. Old corrugated containers are recovered at well over 90 percent in the US, making a plain kraft shipper among the easiest packs to dispose of correctly. Designing out material and void fill reduces waste before recycling enters it.
Operational ease
Clear panel printing supports scanning and picking, and consistent specifications keep packing stations quick. Self-seal and tear strips speed despatch and returns, and fit-to-product sizing controls freight while improving the unboxing.
Multiple Packages: customization made simple
Your box is a brand touchpoint inside and out. Add logos, colour and pattern in sharp print, using flexography for economical volume runs, digital for short runs and SKU variants, and litho-lamination where you want retail-grade imagery on a shipper.
Use interior print for the reveal, or QR codes for setup guides and reorders. Choose matte, gloss or soft-touch finishes. Structural options include tear strips, custom inserts for fragile items, and dielines built around your kitting.
For marketplace sellers, packs can be built toward Amazon’s ISTA 6-Amazon SIOC and Frustration-Free Packaging requirements, which decide whether your product ships in its own box or gets overboxed.
Ship with confidence
Talk to us about sizes, board grades, print methods and timelines. We will guide you to the right spec and send samples.
Low-MOQ ordering starts custom shipping boxes from 100 units, so a new line does not need a pallet of cartons to launch. Production runs about 7 to 10 business days after proof approval, rush from 4 to 5 days on print ready artwork, with free US shipping.
FAQs
What is the minimum order for custom shipping boxes? Low MOQ ordering starts from 100 units, so you can prove a size and spec before committing to volume.
What does 32 ECT mean? Edge Crush Test measures stacking strength. 32 ECT is the standard single wall grade and suits most parcel shipping. Heavier contents or pallet stacking call for 44 ECT or double wall. Mullen burst measures puncture instead, and most ecommerce parcels are specified on ECT.
How do I reduce shipping costs? Right-size the box first, since carriers bill on dimensional weight rather than actual weight. Then drop to a lighter flute where contents allow, and cut void fill.
Are shipping boxes recyclable? Plain corrugated is, with one of the highest recovery rates of any packaging material in the US. Heavy lamination and foil reduce that, so we flag which applies to your build.
