Abstract
A wrapper for enclosing an article. The wrapper is wrapped around the article with an overlapping area of the wrapper being sealed. A line of perforations are aligned in a fixed position relative to the overlapped area so that lateral pressure applied to either side of the perforation line tears the wrapper at the perforations. Preferably, the lower one of the overlapped portions of the wrapper has a cut extending from the side to facilitate separation of wrapper about a tear line.

5487503 - Wrapped article with tear slits - Owned by Fuji Photo Film Co., Ltd. (Kanagawa,JP)

The outer surface of an article is covered with a wrapping film, and the both edges of the film are lap-welded with each other to constitute a body seal section. A first slit is formed along the body seal section, substantially parallel thereto, and is spaced a small distance apart therefrom. A second slit is formed in the body seal section substantially at right angles or an inclined angle to the edge of the body seal section. When the end of the first slit is peeled off, the film splits along the body seal section and also towards the second slit. The second slit helps the split to stretch further in the transverse direction of the article. As a result of this, the wrapping film splits in both the longitudinal and lateral directions thereof.
