Automatic Ultrasonic Sealer
The ultrasonic sealer seals both paper and plastic valve sacks. The paper valve sack has a coating to allow for sealing.
This machine uses ultrasonic high frequency acoustic vibrations to seal a coated valve-sack and creates a solid-state well.
This type of sealer can be used with Autopak’s complete range of valve-sack placers and is ideal for all types of building aggregates, chemicals, food products etc.
