Carton Sealer ImageCarton Sealers | Carton Sealing Machines | Carton Sealing Equipment

Carton Sealing Equipment: Uniform Carton Sealers are used in production environments where a run of the same sized cartons is made, then changed over for the next sized box. Random carton sealing machines are used primarily in order picking operations where the size of the box changes with every order, requiring a carton sealer that can automatically adjust to different sizes on demand. An automatic carton sealing machine folds all of the top flaps prior to sealing whereas a semi-automatic carton sealer requires the operator to close the flaps prior to insertion into carton sealer. After sealing the center line of the box another type of machine called an edge sealer can be added to tape the four edges of the box to make what is known as an "H" seal.

The overwhelming majority of our carton sealer sales use tape to seal the boxes.  However other options such as stapling or hot melt gluing are also available.

Uniform Carton Sealing Machines

Carton Sealers are manufactured in a variety of configurations suitable for your needs.  Uniform carton sealers are the most commonly used on production lines since each carton is the same size as the previous carton. These carton sealers change over very easily from one size to another in a matter of a couple minutes and are available in automatic and semi-automatic versions.

Random Carton Sealing Equipment


Random Carton Sealers are ideal for order picking operations where the size of the carton varies from carton to carton. These carton sealers automatically adjust to the size of each carton as it is presented. They are available in Semi-Automatic and Automatic versions.  Random carton sealers run much slower and cost a lot more than Uniform carton sealers because of the extra mechanisms that adjust the machine individually for each carton.

Customized Carton Sealing Equipment

Many applications exist that are outside of the specifications of our standard carton sealing machines.  Changes required could be as simple as requiring stapling or hot melt application. Others requiring larger or smaller box handling. You might also need higher speeds or ability to handle thicker double corrugate.

Busch Machinery can help you with your customized carton sealing needs.  Just give us a call and we will be happy to discuss your application.

Carton Erectors

While most of our carton sealers can do top and bottom sealing, it is common for many plants to have a carton erector that opens and bottom seals the box prior to the carton packing operations which can be either hand loaded or automatically packed. In those instances carton sealers only perform the final top sealing.

Carton erectors can be automatic or semi-automatic.
