Another possibilty is, that an employee (maybe he got fired) smuggeld the BASF tape into the production line, and the tape was not caught by any control mechanism and reached the final retail box.
Or...maybe it was some kind of sports for some employees to let their private tapes get wrapped in the production line just for fun and they took them home. (...and then they got fired 8o )
Sometimes the adhesive surface on the sides of the wrapper adhesive or heat shrink dissolve over the years, I have this on several NOS tapes.
It is not easy but with some patience it's no big problem to plug another tape inside and glue it together again.
If the sides of the packaging are not dissolved it is very hard to open it without damaging the colored coating of the wrapper.
