This was a new unused tape in its protective plastic bag. The tape had a black backing so I was suspicious it might be sticky. It is not advisable to play sticky tape as it would result in smearing on the heads, which could be difficult to remove. I ran an internet query and discovered that this type of Agfa tape could be "sticky". So I have published the results of my own test.
My test confirmed the tape was bad.
The tape looked and felt fine. I mounted it on the deck and then fast forwarded. The tape wound slower than normal and got progressively slower. There was also a strong synthetic smell. I held both tension arms away from the tape to release some of the tension and the tape speeded up. The tape was obviously causing drag. When the take up reel was full I repeated the operation. During all this tape transfer, just a very few slivers of the black backing material peeled off and dropped down to the floor. Some bits also lodged in the tape winding on the take up reel. This debris was not sticky, it felt dry and did not leave any stain if rubbed between thumb and forefinger. Because the debris was not greasy, I did also try to record onto the tape very briefly near the start of the tape. Surprisingly, it did record but sounded distorted. After the test, I cleaned the heads and tape path with Isopropanol and there was only minor discolouration on the cotton bud.
Both the Agfa reel and box are quite attractive and useful so have been retained but the bad tape has been binned (and not sold on Ebay).
I have previously experienced other types of bad Agfa tape (eg PEM 268). However some types can still be very good (eg PEM 468).
