Shrink Wrapping Systems use shrink wrap and a shrink wrap gun for shrink wrapping packages to tightly hold products together. These systems are available in many styles. Manual shrink wrap machines are portable, light weight, built to last, and requires no assembly. Shrink Wrappers with a Sealer feature an adjustable LED timer, maintenance kit, and starter roll of shrink wrap film. Shrink Wrapping Systems with a Semi-Automatic L Bar Sealer can handle a higher volume of shrink packaging than manual shrink wrap machines by using a shrink tunnel for sealing packages.
