Cardboard Mailer Boxes for Every Ecommerce Business

Cardboard mailer boxes are the backbone of ecommerce fulfilment. They’re the format that works for most products, most shipping routes, and most brand identities — versatile enough to be the default choice and customisable enough to be the right choice when branding and presentation matter.

At The Mailer Boxes, we’ve made cardboard mailer boxes the core of our product range because we know how many different applications they serve. A startup shipping 50 orders a month has the same need as a retailer shipping 5,000 — packaging that’s structurally reliable, clearly branded, and cost-effective. We deliver that at any scale.

Choosing the Right Cardboard Mailer Box

By Board Type

Cardboard is a broad term covering several distinct board types, each with different properties:

• Corrugated board — fluted inner layer for shock absorption; best for heavier or fragile items. See our corrugated mailer boxes.
• Solid bleached board — smooth white surface, excellent print quality; best for lighter retail products
• Kraft board — natural brown, eco-forward aesthetic; best for sustainable brand positioning. See our kraft mailer boxes.
• Double wall — maximum crush resistance; best for heavy or exceptionally fragile items. See our double wall mailer boxes.

By Closure Type

• Tuck top: Standard ecommerce closure — fast, tape-free, clean
• Ear lock / tab lock: More secure for heavier products or longer transit routes
• Sleeved: Two-piece construction for premium presentation — see our sleeved mailer boxes

By Print Requirements

• Plain (unprinted): Fastest lead time, lowest cost — see our plain mailer boxes
• One-colour print: Logo only — clean, cost-effective branding
• Full-colour print: Complete brand expression — suitable for all board types

We have no minimum order requirement. Small quantities are available for sampling, testing new sizes, or seasonal designs. Our pricing scales with volume — the more you order, the lower your cost per unit. Request a quote with your estimated monthly volume and we’ll provide tiered pricing across quantity breaks.
