Vertrod OB

Industrial Impulse Sealer

Industrial pneumatic sealer for front and back operation
or for sealing an uninterrupted flow of film

his industrial line of pneumatically-operated thermal impulse sealers and trim sealers are designed for demanding sealing applications of thick or high temperature materials. Generally used in manually fed packaging or fabricating applications but can also be utilized in conjunction with more automated machinery. The Vertrod OB impulse bar sealer is capable of making hermetic seals with temperatures ranging from 200°F to 650°F available. Open back construction allows the user to operate the machine from the front or rear of the sealer as well as providing pass-through ability for an uninterrupted flow of film. The Vertrod OB employs PAC’s state of the art solid-state control circuitry along with an improved safety system.

The Vertrod OB impulse bar sealer is available in four seal lengths ranging from 14″ to 30″ with a variety of options for flat seals, trim seals, or a combination of both. Contact us for more information and details on custom applications.

The Vertrod OB thermal impulse sealer is made in the USA and includes a 3-year limited warranty.
