Polybag Sealers - Automatic Impulse Sealers

The Model 450 is designed for continuous production, sealing thermoplastic films such as polyethylene and polypropylene.  The Model 450 operates on the impulse sealing method, controlled by a plug-in transistorized circuit board.

By utilizing controlled electronic timers and the uniform pressure provided by an electromagnet, the Model 450 eliminates operator error in the sealing operation.  Once the correct control settings have been established, consistent seals will be maintained automatically, making the last seal as perfect as the first seal.

The Model 450 is ideal for sealing operations in the packaging of candies, food, stationery, drugs, tools, automotive parts and a variety of other products.
