Microfilm box labels

I received a response from Jan Merrill-Oldham regarding the  
foil-backed pressure-sensitive microfilm box labels I blathered to  
everyone about in this space last time.  Here are her comments:

    I tell you--those labels worry me.  They peel up from phase boxes
    and other types of gray/white boxes.  The corners lift away, and
    they start to curl.  Why wouldn't this happen on microfilm boxes
    too?"

I would ask Marcia Watt to go into more detail regarding the accelerated
aging tests to which Gisela Noack subjected sample labels.  Did they
curl or peel?  Did the corners lift away?

Over to anyone.
