Cartoning machines often incorporate an automatic product feeding and loading system, which streamlines the process and eliminates the need for manual labor. Products are typically fed into the cartoning machine via a conveyor system or through an automatic feeder that aligns the products into position. This automatic feeding process enhances the speed and consistency of production, while also reducing the risk of product damage.

In the case of delicate items, such as glass bottles or fragile pharmaceuticals, machines can be equipped with special mechanisms to ensure gentle handling and precise placement into the carton. This feature helps maintain the integrity of the product during packaging.

Sealing is a critical component of the cartoning process. Once the carton is filled, it must be securely sealed to prevent the contents from spilling during transportation and handling. Cartoning machines use various sealing methods, such as tuck-in, glue, or tape sealing, depending on the product requirements.

The sealing system in a cartoning machine is designed for efficiency and reliability. In some cases, the machine may use hot-melt adhesives to bond the carton flaps, while in others, a pressure-sensitive adhesive tape may be applied for quicker sealing. The choice of sealing method can vary based on the type of product and the nature of the packaging material.

Modern cartoning machines are often integrated with other parts of the production line, such as filling machines, labelling machines, and palletizing systems. This seamless integration allows for a fully automated packaging process, where products move from one stage to the next with minimal manual intervention.
