Shrink wrap, on the other hand, is usually wrapped loosely around items and made taut by applied heat.
Large pallets most likely are wrapped in stretch wrap and not shrink wrap. 
Individual products likely are wrapped in shrink wrap.
Stretch wrap will feel stretchy and tension makes it work.
Shrink wrap does not feel stretchy and heat makes it work.

The technical term for what PaulB Wholesale sells is “stretch wrap,” but it has been called shrink wrap by many people because of the way it pulls items together and holds them in place (shrink).
