Porous laminar pellets of comminuted crystalline poly(ethylene terephthalate) waste film are formed. The pellets do not contain a binder, but are coherent since the polymer flakes making up the pellets are mechanically interlocked or intertwined. Rapid drying and solid state polymerization rates are achieved, and the pellets have sufficient structural integrity to survive such processes, but may be readily disintegrated upon completion of such processes if so desired. The pellets are also well adapted for dissolution, such as in glycol monomer for glycolysis, and in molten polymer.
