Inkjet
Continuous or thermal inkjet printing on bottles, cartons and films.
Coding & Inspection for Industrial Packaging Applications
Inkjet, laser and thermal transfer coding, vision, checkweighing and metal detection.
Coding equipment prints batch, date and traceability codes. Inspection equipment checks that each pack is correct, such as weight, code presence, label position or contamination, and rejects the ones that are not.
Types and configurations
Common approaches in this category. The right one depends on your product, pack and output.
Laser
Marks without ink on suitable surfaces. Fume extraction is usually needed.
Thermal transfer
High-resolution printing on flexible film, common on form fill seal machines.
Vision
Cameras check codes, labels, caps and fill levels.
Checkweigher
Weighs every pack and rejects under or overweight packs.
Metal detection
Detects metal contamination in food and pharma products.
How to choose
| Selection factor | Why it matters |
|---|---|
| Code legibility | Surface, speed and code content decide the coding technology. |
| Reject handling | A reliable reject system with confirmation is as important as the detection. |
| Inspection validation | Agree test pieces and how often the system is verified. |
Where it fits in a packaging line
A typical sequence. Your actual line depends on product and pack.
- Filling
- Closing
- Labeling
- Coding
- Vision or checkweighing
- Reject
- Case packing
Technical specifications such as output, accuracy and dimensions are configuration dependent. They are confirmed against the supplier datasheet for each enquiry.

Frequently asked questions
Which coder suits printing on flexible film?
Thermal transfer overprinters are the common choice on film because they give sharp text and barcodes. Inkjet is also used where speed or substrate demand it.
Do I need a checkweigher?
If you sell by declared weight or want to control give-away, a checkweigher gives each-pack evidence and feedback to the filler.
Can inspection data be stored for traceability?
Many systems can log results and rejects. Data needs should be defined early so controls can be planned.
