Does FedEx provide a free return label pouch?

I have scheduled a package pickup with FedEx and I noticed on their confirmation email - "Please note a return label is to be placed in a pouch, and not directly taped on to the package".

Given that I don't have any shipping label pouch myself, I was wondering if FedEx couriers carry shipping label pouches with themselves, or can I just use a ziploc as an alternative to a pouch?

To anyone who is familiar with this, I would appreciate it very much if you could provide me with some tips. Thank you in advance for your help!
