  • Patent number: 8234846
    Abstract: A shrink film applying apparatus includes an article feed for feeding articles for shrink-wrapping at line pressure; a wrapping conveyor driven at a wrapping speed through a wrapping zone, the wrapping conveyor receiving articles from the article feed. First and second films are supplied to the wrapping zone. A plurality of flight bars are individually driven in a path at a variable speed. A sealing mechanism within the wrapping zone seals the first film to the second film at contact points to form a circumferential film unit substantially surrounding grouped articles within loops of second film and a corresponding portion of the first film, the film unit being shrinkable about the grouped articles to form a package. Related methods and subassemblies of the apparatus are disclosed.

  • Publication number: 20110099949
    Abstract: A heat-shrinkable holder is disclosed for securing a plurality of articles. The holder may include a first sheet formed of heat-shrinkable material, and a second sheet formed of heat-shrinkable material and joined to the first sheet. The first sheet and the second sheet each have a substantially equal pre-shrinking length, and are joined so as to create at least two openings therebetween. Each of the openings is sized larger than one of the articles. The first and second sheets are heat-shrinkable to an extent to shrink the openings sufficiently to secure two of the articles together into a unit. Various modifications and additions are possible, including use of more than three sheets, providing for the reading of printed indicia on the articles or holder, providing a handle. Numerous orientations and collections of articles are possible. Related packages including a holder and articles are also disclosed, as well as related methods of manufacture of the holder and package.
