I bought a Keebler Ready Graham Pie Crusts to save time on a desert and the crust tasted  like plastic. We figured it was probably from the plastic packaging covering the crust. We couldnt even eat the desert and had throw it away.  Keebler has wonderful products and I have never had any problems with a Keebler product before this so I feel it may have been because the store I bought it from may have sold me an old one or something.  After I get over that horrible taste of plastic crust I will probably give those crusts another chance.
