A package is formed by folding two halves of a stiff backing together with a plastic window therein. The window extends across the fold in the backing and is of narrow width in the first half of the backing and extends only a relatively short distance from the fold; in the second half of the backing the window is just as narrow at the fold and widens and extends most of the distance to the opposite edge of the backing. The first half of the backing comprises a slit which extends from the window, most of the distance to the other edge of the backing. The package is designed particularly for sterile objects, such as injection needles, tubing, etc.
