Abstract: A tray is erectable from a blank of sheet material for use in a shrink-wrap package. The tray comprises a first panel constituting a base, a second panel joined along one edge to the first panel, and a third panel joined along one edge to a second edge opposing said one edge of the second panel and extending between said second edge of the second panel and the base of the tray. A portion of the third panel is pierced to expose a cut edge which is profiled to conform substantially with a contour of an item it is desired to package on the tray whereby in use said contour abuts said edge to assist in retention of said item in position on the tray.
