Key Features
Custom Corrugated Mailers Engineered for Every Product That Travels Through the Canadian Courier Network
A corrugated mailer that fails during courier transit is not a packaging problem — it is a customer experience failure, a returns cost, and a brand reputation event. The economics are clear: the right corrugated specification costs marginally more than undersized alternatives; a single damaged product return costs many times the price difference. Engineering corrugated mailers correctly is one of the highest-ROI packaging decisions a business makes.
Bespoke Boxes produces custom corrugated mailers for Canadian e-commerce businesses, DTC brands, manufacturers, and distributors. We engineer every corrugated mailer specification from the actual product requirements — weight, fragility, stacking conditions, shipping route — rather than applying generic board weight recommendations that may be inadequate for specific applications.
Single-wall B, C, and E flute for standard applications. Double-wall BC and EB for heavy or fragile products. Triple-wall for industrial applications. ECT and burst strength ratings specified for applications requiring performance documentation. Full CMYK exterior printing for branded delivery experience. Canada Post and courier dimension optimisation for DTC brands managing volumetric weight costs.
Specification Engineering, Not Generic Recommendations
Single-wall C flute is a reasonable starting point for many applications — but a 2kg fragile glass product in a single-wall C flute mailer shipping across three postal zones through Canada Post's handling network is a return waiting to happen. We specify corrugated mailers based on the actual protection engineering of your product — weight, fragility, dimension, stacking load in transit, and the handling conditions of the specific courier network used.
Branded Corrugated as a Delivery Moment
A plain brown corrugated mailer arriving at a customer's door communicates nothing about the brand. A corrugated mailer printed with brand colours, brand mark, and a message creates a brand interaction at the doorstep — a moment that neighbours may see, that the customer photographs, that creates social content. The incremental print cost on corrugated is modest; the brand communication value at delivery scale is significant.

Corrugated Mailers in California — FAQs
What flute type should I use for my corrugated mailer?
E flute provides better print quality and suits lighter products with a premium presentation requirement. B flute provides better stacking strength for standard products. C flute is a middle ground for general e-commerce applications. For heavy or fragile products, double-wall BC provides superior protection. We specify based on your product weight, fragility, and shipping conditions.
What is ECT rating and do I need it?
ECT (Edge Crush Test) measures the compression strength of corrugated board under vertical load — relevant for stacked shipping applications. Standard retail e-commerce typically does not require specific ECT documentation. Industrial and distribution applications where products are pallet-stacked may specify minimum ECT values. We can specify ECT-rated board if your application requires it.
Can corrugated mailers be optimised for Canada Post rates?
Yes. Canada Post applies volumetric weight to packages above certain dimension thresholds. We engineer corrugated mailer dimensions to minimise this penalty while maintaining adequate product protection. At high volumes, this optimisation produces meaningful per-shipment savings.
Can you produce branded corrugated mailers with full colour exterior printing?
Yes. Full CMYK exterior printing is available on corrugated mailers for e-commerce brands wanting a branded delivery experience.
