ABSTRACT:
A method, apparatus, and article of manufacture is disclosed which involves capturing portions of thermosealing packaging material such as film, stretching the film portions over the article to define isolated annuluses of contacting film, and severing the captured film portions together in isolated areas of the film for providing an annular seal about the article thereby providing a packaged article with the film and the annular seal tightly stretched over and conforming to the shape of the article. If the article is a living article such as a grapefruit, the packaging material is a gas permeable film which minimizes moisture migration from the article and from the package while permitting gases to diffuse into and out of the package slowing down the catabolistic destruction of the living article and resulting in greatly extended shelf life of the article.
