What is weigh price labelling?
Weigh price labelling is a process for packs sold by weight. It links weighing information with the pack’s selling price. Separate line functions may then print, apply, code, inspect, or verify the pack.
At a glance:
- Random-weight packages can show a total selling price alongside the price per unit of weight.
- Checkweighing can be treated as a separate function from print-and-apply or coding and included where required.
- A label printer creates labels, an applicator places them, and print-and-apply combines both functions in one system.
- The term does not itself specify whether weighing, price determination, printing, application or inspection use one system or separate equipment.
On a production line, weigh price labelling concerns the weight-related and selling-price information carried by the pack. Inspection remains a separate function.
The term links weight-related information with the selling price, but it does not by itself identify the equipment used to weigh, determine price, print, apply, or inspect the pack. You can specify those functions separately based on the pack and line requirements.
What price information is associated with random-weight packages?
For random-weight packages, price information can include both a total selling price and a price per unit of weight. The exact labelling requirements depend on the market and application.
How does weigh price labelling differ from checkweighing?
Weigh price labelling connects weighing information with price-bearing package labelling. In an end-of-line sequence, checkweighing can sit as a separate weighing control before print-and-apply or coding where required.
The arrangement can therefore have a different scope or equipment setup, meaning the two functions should not be treated as universally combined when specifying production-line labelling systems.
Which labelling functions are relevant to weigh price labelling?
The process can involve separate line functions. Printing creates label content, and application places the label. Coding is a separate line function, code reading reads encoded information, vision inspection checks visible features, and verification checks a defined code result.
Printing, application and print-and-apply
A label printer and a label applicator perform different functions. A printer handles label production, while an applicator places a label on the pack. Industrial label printers are distinct from label applicators.
Print-and-apply systems combine printing and application where a single system performs both, so the equipment description should match the required labelling function.
Line sequence, coding and inspection
In an end-of-line sequence, product discharge can be followed by conveying and spacing, then checkweighing where applicable. Print-and-apply or coding can follow, with vision inspection systems and verification after that, then rejection or diversion.
Coding and code reading remain separate from vision inspection and verification. This sequence illustrates how these functions can sit together without making every weigh price labelling installation the same architecture.
