High-Performance L-bar Sealers

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. 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 reduce the need for a hot knife seal bar with a unique seal wire temperature control system. 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.

The Clamco heavy duty L-bar sealers are 24/7 machines that minimize maintenance, provide consistently strong seals and can be used with a wide range of films.

The Clamco heavy duty L-bar sealer is made in the USA  and includes a 3-year limited warranty.
