Abstract (en)
An easy-to-unwrap heat shrink wrapped article using heat shrinkable wrapping film is proposed, together with a wrapping method and an apparatus for providing the wrapped article. The wrapped article can be characterized by placing an arbitrary item (106) to be wrapped between an upper and a lower fringes (110a) of the heat shrinkable wrapping film (110), storing the item to be wrapped in a bag-like body formed by welding and melt-severing the upper and the lower film fringes overlapping with each other, and covering the entire item to be wrapped by heat shrink of the bag-like body causing the wrapping film to be in tight contact with the item to be wrapped, wherein the wrapped article has a pick-up tab for unwrapping formed so as to project from a welded fringe using a portion of the film fringe when forming the bag-like body by welding and melt-severing of the wrapping film. The pick-up tab has a slit, at a base portion, which will be a tearing point of the wrapped article. With the above mentioned composition, problems with regard to prior arts such as tearing of the wrapping film or the like can be overcome. <IMAGE>
