I would slip it into a ziplock baggie. Punch a hole in a corner and attach to your bag with a zip tie. If you have cardstock I'd print it on that.
While this may work, sometimes the tags get caught between bags. I, personally, would not trust a ziplock for durability.
These tags are smaller. I cut down the paper printable tags into two sections and put each part inside a seperate tag. Then I punch a wider whole in the top, and reinforce it with silver tape!
I use small bungee chord ( can get at many dollar stores or Walmarts) and use that to secure the tag to the bag. Never lost a tag, but one was significantly damaged. If it had been inazip lock it would have become detached, for sure! I keep the second tag in the luggage and when the first is done, I cut it off. Then I use the second tag with bungee chord already precut at home cut and attached to it. Easy to change. I spend maybe 5 minutes the whole trip focused on sending bags.
