I have sealed TDK MA-XG in mint condition. Stored in a dry, dark place. Do you say that they are degraded now?
Your metal tape might be fine if stored well. Chances are you're never going to unseal it anyway.
There are, however, reports of degraded batches of the TDK SA series [0] and other brands.
