imperforate

Lacking any holes

Imperforate means lacking an opening or perforation where one would normally exist.

In medicine, an imperforate anus or hymen is a birth defect where the expected opening is closed or absent.

In philately, imperforate stamps lack the perforated edges that allow easy separation: a sheet of imperforate commemoratives.
