Our small manual systems for shrink wrapping include I-Bar sealers and L-Bar Sealers. Both are commonly used to cut and seal centerfold shrink film. The L-Bar has two seal bars, one at the front that is with the film roll and one across the film. The L-Bar creates a bag with one seal. The I-Bar has only one bar so creating a bag is a two step process. You first cut and seal across the length of the film, separating your package from the roll. Then you rotate the package 90_ and then seal down the open side. Both types then need either a shrink tunnel or a heat gun to apply the heat to shrink the package.
