Adhesive bandages (eg BandAids) won't stick if you keep them too long!
Since BandAids (and other adhesive first aid supplies) are one the 3 essentials ("Beans, Bullets, BandAids"), I have stocked up on a fair number. On a recent trip out of town, I lugged the obligatory first aid kit, which happened to have the oldest box of Band Aids. I knocked the skin off a knuckle, requiring a Band Aid. It fell off! OK, so I try another, and another and another… none of them would stick. What the … ? I don’t recall that happening before.
Luckily I had a backup supply in the car that is much fresher, so one of those worked. But it got me to thinking, I have all these Band Aids (and other misc adhesive medical supplies) tucked away, I wonder how many of them are bad also ? I just researched it and the general consensus is that their shelf life is between 1 and 2 years, then (of COURSE) the adhesive begins to deteriorate. So… what would cause that adhesive to deteriorate ? I would think MOISTURE and/or OXYGEN.
What has been others' experience with this ? I am going to purchase a new lot and preserve them as I have food – in a Mylar bag with oxygen absorbers. Since I live in a low humidity environment I don’t think I will bother with desiccant. Am I on to something or fooling myself if I think I can slow that deterioration down ? I won’t know for a couple of years if it works, but wonder if anyone else has been through this process.
