unperforated
Lacking any punctures
Unperforated means lacking holes or perforations.
The term appears most often with stamps—an unperforated stamp lacks the small holes along its edges that allow easy separation from a sheet.
Unperforated sheets of postage stamps are sometimes printing errors, sometimes intentional collector's items.
The word also describes intact membranes or surfaces: an unperforated eardrum.
