バリ and ピタ are both onomatopoeia (sound effect) words - バリ represents the sound
of tearing the sheet, and ピタ the "sound" of sticking it down tightly.

Onomatopoeia words are only loosely lexicalised and relatively flexible in the
form they take, so they can sometimes be tricky to find in dictionaries, but
you should probably be able to find バリ under バリバリ (as the reduplicated form is
often treated as the most basic form for onomatopoeia) and ピタ perhaps under
ピタっと (since, somewhat unusually for a sound-effect word, it isn't usually
reduplicated) or as its very common variant ぴったり.
