  • Method of packing articles with heat shrinkable films
    Patent number: 4051643
    Abstract: An article is packed with a heat shrinkable film having a width larger than that of the article. The film is moved in contact with a heating member and then immediately wrapped under tension about the article with the opposite side edges of the film protruded beyond the opposite ends of the article. At the same time, the film shrinks about the article to tightly pack it not only on the peripheral surface but also on the end surfaces of the article.
