Use dashes in your comment tags:

[%- ## Comment ###%]

The dashes can go at the beginning or the end, depending on where you
want the white space to be chomped.  I find that doing it on both ends
results in too much chomping, so I usually just put them at the
beginning.

See the 'Chomping Whitespace' section in perldoc
Template::Manual::Syntax.
