Wrappers Seal, Protect, and Unitize

Wrappers can be used for barrier protection or to help promote sales.

Wrapping machines seal pharmaceutical and medical packages, but their purpose extends beyond providing a protective layer of film. Wrappers can combine two packages into one for ease of use or for promotional purposes. Many machines can be customized for special uses or containers of unusual sizes or shapes; another machine offers package unwrapping capability.

A high-speed shrink-unwrapping system automates what previously has been a labor-intensive activity: the unwrapping of bundles of glass vials and placing them on a filling line. The system accepts wrapped bundles, automatically cuts the wrap, strips the wrapper, and delivers the vials to an accumulator for storage and single filing to the filling line. The shrink wrap is discharged into a receptacle for disposal. Also included is an automatic down vial reject device that removes any vials that may have fallen during the process and prevents them from jamming the downstream equipment. Garvey Corp., Blue Anchor, NJ.
