PremiumBespokeArtisanLuxuryMailer Boxes

A mailer box is a one-piece die-cut corrugated blank that folds into a tray with a hinged lid and locking tabs, with no tape and no assembly beyond folding.

A standard shipping carton is a glued tube that needs tape on both ends. The mailer's advantages are that it ships flat, erects in one motion, and opens cleanly without a knife, which matters enormously when the customer is the one opening it. That last point is why e-commerce standardised on the format.

They describe how the lid secures, from least to most.

A tuck-top simply tucks into the front wall. It is the cheapest and fastest to close, and the least secure. A tab-lock adds tabs pushing into slots for a positive mechanical closure. An ear-lock adds side tabs that lock into the walls as well, holding the lid down along its whole length and resisting opening from any direction. Heavier or more valuable contents justify moving up the scale.

Measure the product, add minimal clearance, and resist rounding up.

Dimensional weight pricing charges on the box's volume, so every unnecessary inch is paid for on every parcel, permanently. A box needing lots of void fill is a box that is too big, and the void fill is the visible symptom of an over-sized specification. Right-sizing typically pays back a die charge within weeks at any real volume.

A tear strip is a perforated pull-tab that opens the box in one motion. The double-strip version adds a second adhesive strip that reseals it for returns.

For any business with meaningful return rates, that second strip is a conversion factor, because a package that is easy to send back reduces the friction that stops people ordering. The engineering to get right is perforation tension: strong enough to survive transit, weak enough to tear cleanly. A strip that snaps mid-tear is worse than no strip.

Yes, and it is the highest-return decision in e-commerce packaging.

Interior print costs little on a box already being printed, and it lands at the moment of peak customer attention, as the lid comes up. The doubled walls of a roll-end mailer also give an unusually clean interior surface to print on. For brands whose customers photograph deliveries, it is the difference between a shipment and an unboxing.

Yes for most goods. E-flute mailers routinely survive parcel networks, and heavy or fragile items should step up to B-flute or double wall.

The strength comes from the rolled side walls, which double the material as the box is erected. What mailers do not do is protect against crushing under heavy stacking, so anything travelling as palletised freight rather than as a parcel needs a heavier specification or an outer case.

A poly mailer is a plain film bag. A bubble mailer has a bubble-wrap lining for cushioning.

Poly suits soft goods that cannot be crushed, apparel above all, and is the lightest shipping option available. Bubble adds protection for books, cosmetics and small hard goods. Neither protects against crushing or corner drops, so genuinely fragile items need a box with proper void fill regardless of how much cushioning the envelope claims.

500 units for custom printed mailers, with 7–10 business days production.

Below that, stock mailers with printed sleeves or stickers are the practical route and let a brand test a size before committing to a die. Once the format settles, custom sizing usually pays for itself in freight savings faster than the unit-price difference suggests.
