In a way that is going to depend on how you want to define Blitzkrieg. It wasn't really a stated German doctrine or concept which means exactly what it is, is a bit rubbery. It is not like we can look it up and figure out what was and what was not Blitzkrieg by a strict definition. Hence why there is the occasional discussion as to whether the invasion of Poland could be called a Blitzkrieg.

If you conceive of it as rapid movement and destruction of the enemy (typically in pockets) it very much is just Kesselschlacht, with the incorporation of modern technology to improve mobility and the use of airpower in particular being a continuation of the combined arms-type approach.

On the other hand there is also an interpretation of Blitzkrieg that focuses more on it being almost a morale attack - the penetration of the enemy line, the seemingly uncoordinated attacks from the front and bombing of rear areas was supposed to (according to the theory) create chaos, indecision and ultimately collapse. Kesselschlacht could fit into this concept, but physical destruction of enemy forces wouldn't be the keystone of this conception of Blitzkrieg.
