Packaging for Ecommerce Brands
Build an ecommerce pack around the product, the packing bench and the delivery journey. Compare boxes, protective layers and printed details as one complete system.
Your specification. Your artwork. A clear quotation.
Practical Guidance
Start with the journey your order takes
Ecommerce packaging has several jobs: hold the product, survive handling, make the brand recognisable and remain practical for the team sending it. Begin with the contents and dispatch method. A lightweight textile order and a fragile glass gift set should not inherit the same specification just because they share a logo.
List your common order combinations and packed weights. Include any items that create unusual shapes or need separation. This gives you a useful starting point for choosing one box size, a small range of formats or a combination of packaging types.

01 Work through your brief 4 Standards
01
Choose dimensions around the complete pack
Measure the product with its retail packaging, inner wrap and any insert. Agree whether a proposed box size is internal or external. The outside dimensions and final packed weight matter to your chosen delivery service, so check its current limits before committing to a format. Avoid selecting a box only from a product photograph. A packing trial with the actual contents will show whether the size allows practical assembly, sufficient support and an easy opening experience.
02
Keep presentation details purposeful
Tissue, a branded label and a thank you card can create a consistent impression without requiring every surface to be printed. Choose the details that are useful to the customer: care information, a support address or a clear introduction to the brand. Give shipping labels and seals a planned location. Important artwork should not disappear under the carrier label. If you use internal printing, check what remains visible once the product and protective materials are in place.
03
Compare the cost of packing an order
The empty box price is only one part of the job. Include protective materials, assembly time, storage space, waste and the delivery arrangement. A trial can help you spot a construction that takes too long to prepare or uses more filler than expected. Ask for like-for-like specifications when comparing quotations. Keep material, dimensions, print coverage, quantities and delivery terms visible so you can understand what changes between options.
04
Prepare for repeat orders
Keep the approved artwork and specification together, including any insert and print version. Record which product combinations use each pack. When volumes increase or the range changes, review the fit before simply reordering a larger quantity. The best brief also includes your required arrival date and delivery location. Confirm the schedule for the agreed specification rather than assuming a production time quoted for a different product applies.

Frequently Asked Questions
Clear answers on sizing, minimum order runs, artwork proofs, board calipers, and free tracked UK delivery.
What is the difference between E-flute and B-flute corrugated mailers?
E-flute is approximately 1.5mm thick with tight fluting, providing a smoother surface for high-definition print and crisp fold lines. B-flute is 3.0mm thick, offering heavier crush resistance and cushioning for heavier or fragile shipments.
How does the tear-strip opening enhance the customer unboxing experience?
Integrated red ripcord tear-strips allow customers to zip open the postal carton cleanly in one motion without scissors, preventing accidental knife cuts to the products inside.
Can custom ecommerce mailer boxes be sized to Royal Mail Small Parcel dimensions?
Yes! We specialize in calibrating mailer dimensions to Royal Mail Large Letter (max 353 x 250 x 25mm) and Small Parcel (max 450 x 350 x 160mm) size limits to minimize postal tariffs.
