Blister packaging

Blister packaging is widely used in the pharmaceutical industry for tablets, capsules and medical devices. It offers hygienic sealing, easy dosing and long shelf life – but at the same time places high demands on the precision, contrast and durability of the labelling.

Inkjet marking (CIJ)

Ink marking is a flexible alternative for marking finished blister packs or cards. The marking is non-contact, making the technology quick and easy to integrate into the production line. With the right type of ink, very good contrast can be achieved even on shiny or metallized surfaces.

Advantages:

  • Quick marking of batch numbers and best-before dates.
  • Works on both metallized and transparent films.
  • Adaptable to different surfaces and production speeds.

Read more about Blister packaging

Blister packaging is widely used in the pharmaceutical industry for tablets, capsules and medical devices. It offers hygienic sealing, easy dosing and long shelf life – but at the same time places high demands on the precision, contrast and durability of the labelling.

The information on the blister, such as batch number, best-before date and 2D/Datamatrix codes, is crucial for traceability and patient safety.

The challenge when marking blister packs is that the surface often consists of combined materials, such as aluminum foil, PVC, PET or composite film. These materials are thin, flexible and heat sensitive, making it important to choose a technology that provides sharp markings without damaging the pack or affecting the contents.

The most reliable marking methods for blister packaging are inkjet marking (CIJ) and laser marking.

Questions & Answers (FAQ)

Yes. Laser marking works great on aluminum blisters. The laser removes a thin surface layer and creates clear contrast without damaging the packaging or affecting its tightness. It is a completely contactless and sterile process, ideal for pharmaceutical production.
By integrating vision systems into the production line, labelling is automatically checked in real time. The camera verifies that batch numbers, best-before dates and 2D codes are correct, placed in the right place and fully readable.
It depends on the material the blister is made of and where in the production chain the marking takes place. For finished blister packs, inkjet marking (CIJ) is a flexible and cost-effective option, while laser is best suited for permanent marking with high hygiene requirements.
Yes, but it requires the right type of ink. We use special inks with high contrast and adhesion, adapted for aluminum and metallized films. These dry quickly and are resistant to both friction and moisture.
