Classification Based On The Packaging Size And Type

According to the package size and type, carton sealers have these types:

Uniform Carton Sealers

Operator needs to adjust the width and height of the carton if there is a new carton size. Uniform Carton Sealers are ideal for same size cases.

They are the most familiar sealer type in the production lines, and they have various sizes and speeds to meet your packaging needs. You can adjust them for different-sized boxes. However, when you set them up, they seal packages of the same size. Uniform Carton Sealers have two versions, namely the semi-automatic and automatic versions.

Automatic Uniform Carton Sealers

Automatic uniform Carton Sealers don’t need an operator’s to hold the case flaps. After boxes of similar sizes are placed into , it then fold down the flap of the case and pass the box via the tape head.

Automatic uniform Carton Sealers are best suited when the carton size is same.

Uniform Semi-Automatic Carton Sealers

Semi-Automatic Uniform Carton Sealers are more suitable for the same carton size. Unlike uniform automatic Carton Sealers, they require the services of an operator. The tape heads are easy to adjust, and they seal the top and the bottom.

Semi-Automatic Uniform Carton Sealers are ideal for sealing lower volumes of similar-sized cases. First, you introduce the boxes through a belt system that runs linearly through the machine for closing the upper and lower flaps fast. Then, the machine seals the box and adjusts it manually in height and weight.

  • They seal both the top and bottom of the case.

Random Carton Sealers

Random carton sealers are a great choice of machines for sealing boxes of various sizes.  They can adjust the height of their tape head to any carton size. Also, the tape head contains sensory equipment and can either go higher or lower until it locales its appropriate height. Finally, the case goes through a powerful roller system and then seals the flaps.

Random Carton Sealing machines are ideal for different sizes of cartons. The machine is designed in a way that it can adjust itself automatically based on the size of each carton. Because random carton sealers have more mechanical and technological parts, they are usually costlier than uniform sealers. Therefore, they are ideal for  different sizes of cartons.

Random Carton Sealing machines are also of two types which are automatic and semi-automatic versions.

Automatic Random Carton Sealers

Automatic Random Carton Sealers provide full automation sealing for different sizes of cases. To operate it, first introduce different sizes of cartons. And the automated arms will find the height of the box; then, the sealer will fold the top flaps of the package. After folding the flaps, the case will move through the tape head and seal the flaps. Then, the sealed packages move to the back end of the carton sealer for handling.

The operator folds it and introduces the box into the Carton Sealer to commence the sealing. Then, the semi-automatic Carton Sealer adjusts to the height and size of the box and moves through the case via the tape head. Then, finished boxes move out the back of the machine to a conveyor system.
