Question 1

What thickness are courier bags usually?

Accepted Answer

Fifty to 60 micron covers most e-commerce. Fifty works for apparel and soft goods, 60 is the safe default for mixed orders, and 70 to 80 is for heavy or sharp-cornered items. Going thicker than you need is the most common way sellers overspend on packing.

Question 2

What makes a courier bag tamper-proof?

Accepted Answer

Security tape that fails before its adhesive does, so lifting the flap either shreds the tape or reveals a VOID pattern. Add opaque film so nobody can see what is inside, and a wide side seam so the bag does not burst in sorting and look like tampering. Ordinary peel-and-stick tape is not tamper-evident, whatever the listing says.

Question 3

Can you print our brand on courier bags?

Accepted Answer

Yes, flexo up to 4 colours. Printed courier bags start at 10,000 pieces per size and design because plates and setup are fixed costs. Below that, plain bags with a printed label are almost always cheaper per shipment.

Question 4

Do you supply bags with a POD document pocket?

Accepted Answer

Yes. A transparent jacket on the front holds the shipping label and invoice so the paperwork does not travel loose inside the parcel. It adds a small amount per piece. Most courier networks and 3PLs ask for it, most D2C brands skip it and print labels directly.

Question 5

What is the minimum order for courier bags?

Accepted Answer

5,000 pieces per size for plain bags, 10,000 for printed. Courier bags are a high-volume product, so the economics only work above those quantities. If you need less to trial a size, tell us and we will see what is running on the line.
