Courier Bags & Postage Satchels

QIS courier bags (also known as postage satchels, poly mailers, mailing satchels, or shipping satchels) are the go-to packaging for Australian online stores, eCommerce sellers, 3PL fulfilment warehouses, subscription box businesses, and anyone shipping parcels by Australia Post, StarTrack, TNT, Aramex, CouriersPlease, Sendle, DHL, or other Australian courier services. Every bag is built for real-world fulfilment: tamper-evident, self-sealing, water-resistant, tear-resistant, and lightweight to keep shipping costs down.

Choose from three styles across nine popular sizes:

• White Courier Air Bags — opaque white exterior, black interior, 55µm, 100% recycled. The standard satchel for most eCommerce shipping (9 sizes, A5 to A1).
• Matte Black Courier Bags — premium matte black finish for fashion brands, luxury goods, and brand-conscious sellers wanting a more upmarket unboxing experience.
• Custom Printed Courier Bags — your brand, logo, or messaging printed on the bag. 1-colour and 2-colour print options, single or double-sided.

All courier bags ship same-day on orders placed before 12pm. Australia-wide delivery from our Brisbane warehouse. Backed by QIS's 5% price-beat guarantee.

Why QIS Courier Bags?

Built for the real demands of high-volume eCommerce shipping:

• Tamper-evident security strip — once sealed, the bag cannot be opened without visible damage, protecting both you and your customers
• Permanent self-seal closure — strong adhesive strip bonds quickly and stays sealed through transit, even in hot Australian conditions
• Tear-resistant 55µm film — withstands rough handling through the courier and Australia Post network
• Water-resistant — protects contents from rain, mud, and damp conditions during delivery
• Opaque white exterior with black interior — addresses and labels stand out clearly while keeping sensitive contents hidden from view
• 100% recycled plastic — reduces virgin plastic use without compromising strength or print quality
• Lightweight — keeps shipping costs down compared to boxes for soft, non-fragile items
• Compatible with all thermal shipping labels — labels from Australia Post, StarTrack, Sendle, Aramex, CouriersPlease and others stick reliably and stay attached
• Sold in convenient packs of 100 — wholesale tiers available for high-volume warehouses

Recommended Weight Capacity

Courier bags are best for soft, non-fragile items where a box isn't necessary. As a general guide:

• Smaller sizes (A5, A4, A3) — up to 3kg of soft contents
• Mid sizes (350×480, 440×500, A2) — up to 5kg of soft contents
• Larger sizes (600×600, 650×700, A1) — up to 10kg of soft contents

For parcels containing fragile items, electronics, glass, or anything that needs cushioning, consider pairing courier bags with bubble wrap for internal cushioning, or use our Jiffy Padded Bags or HoneyComb Padded Mailers for built-in cushioning.

Custom Printed Courier Bags — Branded Packaging for Your Business

Plain courier bags are functional, but custom-printed courier bags turn every delivery into a brand experience. QIS offers custom printing on courier bags with your logo, brand colours, or promotional messaging, available in:

• 1 colour print, 1 side — entry-level branded option
• 1 colour print, 2 sides — branding on both faces
• 2 colour print, 1 side — multi-colour brand presentation
• 2 colours print, 2 sides — full multi-colour branding both sides

Custom printing typically requires minimum order quantities and longer lead times than stock bags. We accept artwork in vector .AI, .EPS, or high-resolution .PDF format. For pricing, artwork specifications, and lead times on custom-printed courier bags, please fill out our enquiry form or call 1800 555 343.

Premium Matte Black Courier Bags

For fashion brands, luxury goods, and businesses wanting a more premium unboxing experience, our Matte Black Courier Bags offer the same tamper-evident security and self-seal closure as our white range, but with a sophisticated matte black finish that signals quality from the moment the parcel arrives. Popular with apparel, beauty, jewellery, and lifestyle brands.

How to Use Courier Air Bags

1. Choose the right size for your product — leave at least 30mm of space at the top for clean sealing
2. Place your item inside the bag (with bubble wrap if fragile)
3. Peel the protective strip from the adhesive seal
4. Fold the top flap over and press firmly along the entire length to activate the adhesive
5. Attach your shipping label (thermal labels stick reliably to the bag surface)
6. Hand to your courier or post — the tamper-evident strip means any tampering is visible to your customer on arrival
