Cartoning machines are designed to automate the process of erecting carton blanks, aligning products, loading products into erected folding cartons, and finishing closure. [1]
Evidently, as it can be perceived from this description of operation principle, cartoning machines have basically all their processes dealing with cartons. An inevitable result due to this fact is that how smooth the cartoning machine may work. Its consistency will also depend on the carton styles, how well the die-line is designed, and how reliably and adequately the cartons are manufactured.
As an experienced manufacturer of cartoners, we would like to share with you in this session the key factors about cartons which will affect the reliability, smoothness, and consistency of a cartoning machine’s operation.
The Operation Principle of Cartoning Machines is All About Cartons
Despite the fact that a cartoning machine can be designed into right hand or left hand, the general principles of cartoning operation processes are all about manipulating the cartons by erecting blanks, folding flaps and closing the tabs and panels.
The reliability of these processes, although has a lot of factors to do with how the cartoning machine is designed, depends on as well to a considerable extent how well are the cartons manufactured and prepared.

Factors, Metrics, and Parameters of Cartons that Make Difference for Cartoning
Grammage (gram per square meter)
Grammage of cartons refers to the weight of the paperboard per unit area, typically measured in grams per square meter (gsm). For example, the terminology that you may find on a cartoning machine proposal that written as 350g/m^2 is referred to grammage, which is an important factor in determining the thickness, strength, and durability of the carton.
Cartons of 250 gsm and 350 gsm are of different performances when used for cartoning processes, though some other factors like cost might be a concern.
Cartons with 250 gsm are thinner, lighter, more flexible, and generally less expensive, suitable for lighter products, whereas 350 gsm cartons are thicker, heavier, more rigid, and durable, thus providing a more reliable carton assembly process.
Cartons with more grammage can provide better protection and a premium surface for high-quality printing, ideal for heavier or more delicate items that require additional structural support.
Die Cut and Flap Sizes
Prosper die cut and sizing of cartons do not only matter for how adequately the cartons may fit the products, yet are also critical for the consistency of cartoning machine’s output and operation.
Even some finest differences in sizing of the die-cut can affect how reliably the cartons are folded and assembled by the cartoning machine. One of the typical factor that designers and manufacturers usually neglect is the sizing of locking tab slit or locking slit which plays an essential role for the situation of tuck-in closure.
Locking Slit

A locking tab slit is a cut or slit made in a piece of material, typically cardboard or paperboard, designed to accommodate a locking tab. The locking tab is a small, protruding piece that fits into the slit to secure flaps or panels in place. This mechanism is commonly used in packaging to ensure that boxes or cartons remain securely closed without the need for additional adhesives or fasteners. The locking tab slit provides a simple yet effective method for creating a stable and reliable closure.
Scoring and Creasing Line
Scoring lines are partial cuts that make folding easier, while creasing lines are indentations that guide folds.
Scoring lines help cartons fold accurately, maintain structural integrity, and work smoothly in automated machines. All folding processes including those for closure panel, dust flaps and even the assembly of blanks rely on how well and accurately the creasing lines have been prepared during the carton’s manufacturing processes. Proper scoring and creasing allows easy assembly, prevent material damage, and contribute to a professional appearance.
Pre-Folding
Pre-folding is a crucial process in the manufacturing of cardboard boxes.
The main purposes of pre-folding include ensuring the accuracy and quality of the folds, which helps to avoid any issues during final assembly. Pre-folding is critical for increasing production efficiency by making the final assembly process faster and easier on a cartoner, despite the fact that a cartoning machine can be designed with pre-break functions.
