This report summarizes the results of an investigation of the bond strength of paper - polypropylene - paper (PPP) laminates. The strength has been measured with a peel test for the as--received laminates of different manufacturers, after thermal aging in air and nitrogen, after static thermal age in oil at room temperature and 90{degrees}C as well as after cyclic thermal aging in oil. Differential swelling of the paper and polypropylene at 90{degrees}C leads to a strong decrease in peel strength. Differential thermal expansion at 90{degrees}C is not as important. Cyclic thermal aging in oil leads to the greatest decrease in peel strength. The results further our knowledge of information that should be considered in preparing a PPP specification. 19 refs., 7 figs., 12 tabs.
