Side sealers are generally considered the most flexible of the various wrapper styles and are often chosen by contract packagers who have the need to wrap a never-ending variety of packages. These wrappers encapsulate products in a continuous tube of film, sealing along one side of the package and then separating them into individual units downstream using a cross seal. Unlike L-bar sealers, side seal machines can run random products of infinite length.

Two-belt and three-belt side seal wrappers

Side seal wrappers come in two basic configurations: two-belt and three-belt. Two-belt sealers are made more compact by eliminating one of the infeed belts and making the end seal prior to the side seal. Not much longer than an L-sealer, two-belt units are often the logical choice when customers find themselves needing the ability to wrap longer products without greatly expanding the length of production lines. Three-belt side sealers have the added advantage of being able to precisely space the products prior to entering the wrapping area.
