It was reported that the positronium (Ps) formation in polymers was enhanced near breakdown voltage. It cannot be explained by the Spur Reaction Model. We investigated the electric field effect on positron annihilation lifetime for Kapton that has no Ps formation. We observed elongation of the free positron annihilation lifetime instead of the enhancement of Ps formation. It is possible to explain that drift of positrons causes smaller annihilation probability, i.e. longer lifetime. Now it is possible to explain the Ps formation enhancement reported previously could be caused by the elongation of the lifetime of the free positrons.
