A method for hermetically sealing a bulk article wherein a strip of wrapping material is initially positioned onto an article such that extending ends of the wrapping material strip extend from away from an edge of the article, each end having a different length. The article is rotated to cause the ends of the strip to cover an uncovered side of the article with a fin-like section extending therefrom away from the article which can be sealed without contacting the article. The fin-like section is cooled and folded onto the top of the article so as to form an axial seam. Lateral ends of the wrapping material strip are then sealed to complete the hermetic sealing process.
