The Clamco heavy duty L-bar sealers are available in several sizes—4L, 6L, and the extra large 8L for packaging and sealing a variety of products. Clamco heavy duty L-bar sealers can be used with a wide range of films due to their precise temperature and speed controls. These dependable L-bar sealers are equipped with a sealing arm that works manually, pneumatically, or with a motor (motor drive available on the 6L and 8L). The robust design of the Clamco systems provides the framework for greater productivity and ensures consistently strong seals.

The use of integrated application-specific controls allow for easy and fast operator set-up and provide years of trouble-free operation. The Clamco L-bar sealers offer a hot knife seal bar option for sealing PVC and polyethylene films. In addition to the temperature control, the Clamco L-Bar sealer has dwell control for continued seal time under pressure, and speed control for the product power take-away conveyor. The Clamco system also has a convenient adjustable height control for the power take-away conveyor to provide smooth product transfer.
