Corrugated Shipping Boxes

Corrugated Shipping Boxes Built to Survive Transit

Corrugated shipping boxes are engineered for the rough handling of couriers and freight, protecting goods all the way from the warehouse to the doorstep. Choosing the right flute, strength rating and box size together keeps both damage rates and shipping costs low, and a box designed for the journey pays for itself many times over in avoided returns and replacements.

Construction for the Courier Journey

Most shipping boxes use the regular slotted container, or FEFCO 0201, where all flaps are the same depth and the outer pair meet at the centre to close top and bottom. In single wall B or C flute this gives a strong, sealable carton that resists the compression, drops and vibration of automated sorting hubs. The fluted core cushions impacts while the liners keep the walls rigid, so contents stay protected across every handoff between conveyor, van and doorstep. For heavier or more fragile consignments the same style is built in double wall, giving extra crush and puncture resistance without changing how the box is packed or sealed.

Strength Ratings and ISTA Testing

Board is specified by the Edge Crush Test for stacking strength and the Mullen burst test for puncture resistance. Around 32 ECT covers typical single-parcel ecommerce, while heavier or stacked freight moves to double wall past 44 ECT. We can validate a design against the relevant ISTA test series, which simulate the drops, random vibration and compression a parcel really meets in distribution. Testing to a recognised protocol means you know the box performs before it ships in volume, rather than discovering weaknesses later through damaged goods, negative reviews and the cost of returns. For fragile or high-value items, this upfront validation is far cheaper than the claims and goodwill lost to a batch that fails in transit.

• 32 ECT for standard parcels
• Double wall for heavy loads
• Validated to ISTA profiles

Right-Sizing to Cut Cost and Damage

Carriers bill on dimensional weight, so an oversized box costs more on every shipment and lets contents shift and break inside. We build to your product dimensions with minimal headspace, which reduces loose fill, lowers the billed size and holds goods still throughout the journey. Right-sizing is one of the fastest and most reliable ways to trim both freight spend and damage claims at the same time, and it improves the customer experience by removing the wasteful, half-empty box that so often arrives at the door.

Where Shipping Boxes Are Used

From ecommerce fulfilment and subscription dispatch to wholesale replenishment, spare-parts distribution and customer returns, corrugated shipping boxes handle almost any parcel a business sends. Standardising a small range of well-sized cartons speeds picking and packing, simplifies stock holding and keeps every SKU correctly protected. A consistent shipping range also makes automated case erecting and sealing far easier to run, which matters as order volumes grow. Fewer box sizes in the mix means simpler forecasting, better buying power on each line and less warehouse space tied up in packaging stock.

Printing, Labels and Sealing

Kraft liner offers an economical, natural finish that reads as sustainable, while white liner brightens CMYK branding for a better doorstep experience and stronger repeat custom. A smooth B flute face takes shipping labels, address blocks and barcodes cleanly without smudging, which keeps automated scanning reliable at the carrier hub. Boxes seal reliably with tape or hot melt at the RSC flaps, and tear strips or double-adhesive returns closures can be added for an easier unboxing and returns flow. Consistent print and label placement across your range also speeds manual sorting and reduces mis-scans.

• Kraft or white liner options
• Smooth face for labels
• Tape or hot-melt sealing

Recyclability and Wholesale Ordering

Corrugated is kerbside recyclable and largely made from recovered fibre, so lean, right-sized shipping boxes reduce cost and environmental impact together. We help you settle on the lightest grade that still clears transit testing, and keep the construction single-material so customers can recycle the whole box without separating parts.
