The outer surface of an article is covered with a wrapping film, and both edges of the film are lap-welded with each other to constitute a body seal section. Both of the upper and lower edges of the film overlap extending out of an article to be wrapped are folded to the inside of the article, whereby upper and lower folded parts are formed. These folded parts overlap with each other, and are bonded and lap-welded together, thereby constituting a side seal section. An unbonded part is formed along the periphery of the upper folded part, wherein the upper folded part and the lower folded part are not bonded together. Two slits are formed in that unbonded part substantially at right angles or an inclined angle to the edge of the upper folded part, and spaced apart from each other by a certain interval. When an interval between the slits is peeled off with a finger, the unbonded part splits along the slits, and hence the side seal section splits. The split made by the slits is extended along the body seal section by pulling the split further toward the inside of the article, whereby the body seal section is removed.
An assembly including a processed cheese portion (22) and a package (26) closely wrapping the portion. The package includes an element which itself comprises a film (2) tightly wrapping the portion and in contact therewith, and tear-initiating member (11) for enabling the sheet (2) to be torn along at least one tear line (8) when a gripping tab (10) of the element is pulled. At least a first part of the or each tear line (8) is defined by or made from a material of the film (2).
