An EMI gasket blocks electromagnetic radiation between electrically conductive bodies and encompasses an area using a number of adjacent segments, each generally formed as a resilient core section. An electrically conductive surface material bears against the conductive bodies and extends over the segments, the surface material preferably being formed of a metallized polymer sheet. The polymer sheet is coupled through between the opposite faces of the gasket along lengthwise seams where either the sheet is depressed into the seam or coupled by a conductive adhesive, such that the opposite faces of the gasket are electrically coupled between the segments. The conductive material extending through the gasket to couple the opposite faces provides conducting paths that improve shielding efficiency. The seal can be die cut, including cutting through the width of one or more segments, and remains intact, providing many of the benefits of both wide seals or gaskets and elongated narrow seals.
