Abstract
The objective of this invention is to provide a handle for carrying an article or a bundle of bottles that is more resistant to tearing and delaminating and can carry heavy loads. This is accomplished by placing a strip on the inside of the wrapping material so that the strip that forms the handle is enclosed within the wrapping material. The strip film maintains direct contact with the wrapping film. Direct contact is achieved by electrostatic bonding of the handle film on the wrapping film. Therefor more than 80% of the handle seals to the wrapping film.
Claims11
A process for heat shrinking a film wrapped bundle or an article having a handle strip film bonded to the inside of a wrapping film, wherein the handle strip is made from a material that seals to the wrapping film during the heat shrinking and comprising the steps of:
- receiving the handle strip film and the wrapping film in a static unit having a ground strap or bar and having a static probe receiving current and housed in an open-ended insulator sleeve, wherein the ground strap or bar and static probe are configured in a directly overlapping configuration;
- electrostatically bonding the handle strip to the wrapping film by passing the handle strip film and the wrapping film overlapping and between the ground strap or bar and static probe;
- receiving the electrostatically bonded handle strip and wrapping film directly to a perforation module and providing openings in the wrapping film adjacent the handle strip that would allow one to grip over the handle;
- film wrapping the bundle having the bonded strip over the bundle so that the strip is enclosed by the wrapping film;
- and
- heat shrinking the film wrapped article causing the strip to seal to the film wrapped article.
