What is case labelling?
Case labelling is a working term for applying identification labels to cases within a production or logistics process. The requirement may involve producing a label, applying a pre-printed label, or combining variable-data printing and automated application. The term describes the case-focused application rather than one specific machine type.
Logistics labelling requirements vary by application, so case-labelling requirements should be defined for the specific process rather than treated as universally standardised.
Key takeaways:
- A label printer creates labels for later application or integration; it does not place the label onto the case.
- A label applicator places a pre-printed pressure-sensitive label onto the case, while print-and-apply adds variable-data printing before application.
- Case-labelling assessment should define the case format, target label panel, required data, line presentation and any downstream inspection.
- Case labelling describes the application to a case; pallet labelling addresses a different load format and should be specified separately.
Printing, applying and print-and-apply functions
Case labelling can use a printer, an applicator or a print-and-apply system. Separating these functions first prevents the equipment scope from being confused with the case application itself and clarifies what must happen at the labelling point.
Separate labelling functions
An industrial label printer produces the required label but does not automatically apply it to the case.
An applicator receives a pre-printed pressure-sensitive label and places it onto the presented case.
Print-and-apply combines label production and application in one process. This is the relevant function when variable information must be printed before the label is automatically applied.
Specify the requirement
Start by defining what needs to happen at the case-labelling point.
If labels are already printed, the requirement may centre on application. If variable information must be produced as cases reach the labelling station, print & apply may be the appropriate functional category. A standalone printer remains a different requirement where printing and application are separate steps.
This distinction should be made before comparing individual machines.
Case labelling system assessment inputs
A useful case-labelling assessment starts with the physical case, the panel that needs the label and how the case reaches that application point. The label function and wider line requirements can then be specified around those case-specific inputs.
Case format and label position
Record the case format and dimensions, then identify the panel or position where the label must be applied.
This matters because the case has to be presented to the application point in a way that matches the required label location. Different case formats or label positions can therefore change the handling and application arrangement even when the information printed on the label stays the same.
The assessment should also record whether the case remains stable as it moves through the labelling point or whether additional handling is required to maintain presentation.
The required panel, case dimensions and presentation should therefore be defined before selecting a box labelling machine.
Label data and application function
Define what the case label needs to contain before selecting the equipment category.
A pre-printed label creates a different requirement from a label carrying variable production, identification or logistics data generated at the labelling point. This decision establishes whether the system needs application only or a combined printing-and-application function.
Label size and the required application position should also be considered against the selected equipment rather than assumed to suit every applicator configuration.
Case presentation, speed and direction
Record how cases approach the labelling point, including line direction and required production speed.
The labelling equipment must fit the way cases move through that point. Where spacing or presentation varies, surrounding product handling equipment can be specified separately to control the infeed rather than treating those functions as part of the applicator itself.
This keeps the case-handling requirement distinct from the label function.
Integration, environment and inspection
Assess the available footprint, operating environment, existing controls and conveyor arrangement around the labelling station.
Any inspection requirement should also be defined separately. A case may need a post-application check for a configured label or code criterion, but inspection is not an automatic function of the printer or applicator.
Where an unsuccessful case needs to be removed from the line, rejection or diversion is another separate downstream function.
Presentation, inspection and downstream handling
Case labelling depends on the case reaching the application point in the required presentation.
Pre-labelling handling can support spacing and stabilisation where the incoming case flow requires it. These functions help establish the presentation needed by the labelling equipment without changing what the applicator or printer itself does.
After application, the case can move into separate inspection, rejection or downstream conveying stages according to the wider line requirement.
This separation is useful when specifying a complete system: case handling controls movement and presentation, labelling equipment performs the defined label function, and inspection or rejection equipment handles subsequent quality checks.
Case labelling and print-and-apply labelling
Case labelling and print-and-apply labelling describe different aspects of the requirement.
Case labelling describes the application context: the item being labelled is a case.
Print-and-apply describes the function: variable information is printed and the newly produced label is then automatically applied.
A case-labelling system may therefore use print-and-apply, but the two terms are not synonyms. Cases can also be labelled using pre-printed labels and application-only equipment.
The same distinction separates case labelling from a pallet labelling system. The equipment function may be similar, but the item being presented and labelled is different.
ALS Identify supports case labelling system selection
ALS Identify supports case and box labelling requirements across equipment selection and wider line integration. Review label applicators when the requirement involves automated application of pre-printed labels, or product handling systems where case spacing, presentation, inspection or downstream movement also needs to be addressed.
Bring the case format, target label position, required label data and line arrangement to ALS Identify for review.
