What is an I-bar shrink wrapper?
I-Bar shrink wrappers are a type of shrink-wrap machine that uses a single bar to seal shrink-wrap film. Three total passes are typically required to seal all sides of the film around a package. I-Bar shrink wrappers are very popular with video rental shops who sell used DVDs and CDs. These types of shrink-wrap machines are also very popular with low to mid-volume shrink wrapping. The end result looks great, but it does take longer to package a product with this type of machine than with an L-bar shrink-wrap machine, which seals three sides in one pass. The advantage of an I-bar shrink wrapper is the ability to move and manipulate the shrink film around a product with ease. You can also seal multiple angles around a product and are not limited to a four-sided pattern. I-bar systems are also not limited to a tunnel height, unless a tunnel is being used to shrink the film. Most I-bar shrink wrap systems use a heat gun, which looks a lot like a hair drier, to shrink the film.
