Flipkart Security Bag: How the Double Seal Protects Orders

“Security bag” is what Flipkart sellers call the barcode courier bag with a strong seal. The name matters because the seal is the whole point: it's your evidence if something goes missing between your table and the customer.

How the double seal works

• The flap has two adhesive strips instead of one.
• The adhesive bonds to the film. Pulling the flap tears the bag or leaves a visible mark.
• If one strip is weak, the second still keeps the bag closed.

Heat or a cold glue gun can't open it cleanly either, which is what makes it a security bag rather than a plain mailer.

Using a security bag to win claims

1. Record a packing video showing the product going in and the bag being sealed, with the AWB visible.
2. Stick the label flat, away from the seal.
3. Keep the video for at least 60 days.

If the customer says the parcel arrived opened, a sealed security bag on video is your strongest proof. Read tamper-proof packaging benefits for more.

Security bag vs plain polybag

A plain polybag is cheaper and fine for low-value items. For anything a courier might be tempted by, like phones accessories, branded clothing or cosmetics, the security bag is worth the small extra cost. Compare with plain polybag prices.
