What Are Mailing Boxes?
A mailing box - also called a mailing box or postage mailing box - is a self-locking cardboard carton that replaces envelopes or satchels when you need extra protection. Built for the postal system, these boxes resist compression and impact to keep products safe in transit.
Because they're both protective and presentation-ready, mailing boxes are a favourite for online brands that want each delivery to feel premium. Smooth printable panels, crisp folds and snug closures make them perfect for subscriptions, launch kits and D2C parcels where the unboxing moment matters.

- Australian made: produced in Brisbane from responsibly sourced materials.
- Eco-friendly: recyclable board and sustainable inks.
- Brand-ready: from a minimal custom mailing box with your logo to bold full-wrap print.
- Fast delivery: quick turnarounds across Sydney, Melbourne, Gold Coast & regional areas.

Mailing Box Buying Guide (Australia)
Picking the right postage box = fewer damages, cheaper freight, and better unboxing.
- Size & fit
Measure product L x W x H then add 3-10 mm for wrap/void fill. For heavy items, keep one dimension small to reduce crush. - Board & strength
E-flute (1.5-2 mm): sleek, lighter, great for cosmetics, apparel, merch.
B-flute (3 mm): tougher for bulk/heavier SKUs.
Choose Kraft outside for scuff-tolerant shipping; White for premium print. - Branding options
Plain / labels (lowest MOQs, fast).
Single-colour flexo (cost-effective, bold).
Full-colour digital (vibrant, small runs).
Litho-lam (flagship look at higher volumes). - Postage & freight
Smaller volumes weight-charge; many couriers charge by cubic. Tight fit saves money and reduces damage. - Sustainability
Australian-made board, recyclable, water-based inks available. Use right-sizing to cut void fill. - Assembly & packing
Mail box styles pop up fast; use paper tape, add corner protection for fragile items.
Quick picks
- Best for first-time shippers: E-flute Kraft mailers.
- Best presentation: White mailer with digital print.
- Best for weighty goods: B-flute Kraft with tight fit.
Frequently Asked Questions
What are mailer boxes made from?
Most of Pakko's mailer boxes are made from corrugated board in E or B flute.
Are mailer boxes eco-friendly and recyclable?
Yes. Pakko mailer boxes use sustainable, recyclable cardboard and are designed to reduce environmental impact.
How do I choose the right size mailer box for my products?
1) Measure your product’s length, width, and height (include any inner packaging). 2) Add space for cushioning (bubble wrap/void fill). 3) Use box measurements in the order: length (panel below the opening), width (side panels without flaps), height (standing side, excluding flaps). When you’re ready, browse Pakko’s range: https://www.pakko.com.au/shop/mailer-boxes
Can I customize the inside of the mailer box?
Yes. We can print inside and outside surfaces—logos, brand colors, messages, and more—to create a fully branded unboxing experience.
What is the difference between a mailer box and a shipping box?
Mailer boxes are self-locking and presentation-ready for e-commerce and smaller items; they usually don’t need tape. Shipping boxes are taped closed, use heavier board, and are better for large or heavy freight.
Are your mailer boxes suitable for international shipping?
Yes. The self-locking design provides secure closure for most products. For fragile or heavy items, add cushioning and choose an appropriate board grade.
Do I need to use tape to seal a mailer box?
No. Our mailer boxes use a self-locking design with tabs and flaps. Tape is optional for extra security in transit.
Where can I buy mailer boxes near me?
Pakko manufactures in Brisbane and ships Australia-wide, so you can get mailer (mailing) boxes fast whether you’re in Sydney, Melbourne, the Gold Coast, or beyond.
