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.

A wrapper for enclosing an article, comprising:
- a wrapping film enclosing an article;
- a series of perforations in said wrapping film,
- two end portions of the wrapping film overlapping in an overlap area and said series of perforations being located adjacent said overlap area,
- wherein said two overlapping end portions of said wrapping film are bonded to each other in said overlap area,
- and wherein the inner one of said two overlapping end portions has a cut extending from its end adjacent said series of perforations;
- such that, said wrapping film may be severed along the line perforations parallel to the overlapping end portions and the wrapping film may be torn about the article at right angles to the wrapping film overlap area, and wherein,
- the cut forms two ear pieces at said overlapping end portions to facilitate pulling of respective ear pieces in opposite direction so as to further tear the wrapping film along the overlapping area.
