Is there a way to identify when tape rolls were made? I have bought a few rolls from a local wholesale house that were clearly out of date as the adhesive had bonded to the point of making it worthless. Thanks.
 
They may have been subject to too much heat, too. Sometimes, a roll of tape will turn into a cone.

Just take it back and get it replaced. I don't think it matters when it was made as tape doesn't actually have an expiration date. I agree with the poster who said it was probably heat. It probably sat in a hot vehicle or some other warm place. One of the things I have occasionally wondered about is what is the temperature rating of black tape. Supposedly it can be used to repair damaged insulation on just about any kind of conductor and so you would think that the temperature spec on black tape would be at least as warm as the rating of any conductor that it would be used on. You wouldn't think it could get that hot just sitting in the sun.
 
Had a couple of boxes of it sitting on the shelf for who knows how long. Went to use a roll and that's what happens. I just had that happen to a pack of masking tape too.

Moral of the story is just buy what you can use in a reasonable length of time. And be careful of those sales and deals.

I've learned to check the dates on everything expirable. A couple weeks ago I was sent an expired can of chico.
