The Bracha Rishona on Pringles is Borei Pri Hoadama, and the Bracha Acharona is Borei Nefashos.
The Bracha is Hoadama as per Rav Belsky, since today most potatoes are processed into flakes and flour. (See Mishnah Berurah 202:42-44)
Blessed are You Hashem our God King of the universe, Who creates the fruits of the ground.
Baruch Atah Adonai, Eloheinu Melech Haolam, Borei Pri Hoadama.
Blessed are You, Hashem our God, King of the universe, Who creates numerous living things with their deficiencies; for all that You have created with which to maintain the life of every being. Blessed is He, the life of the worlds.
Baruch Atah Adonai Eloheinu Melech Haolam, Borei Nefashos Rabos V'chesronan Al Kol Ma Shebarasa L'hachayos Bahem Nefesh Kol Chai, Baruch Chei Haolamim.
