Ink marking is a common and cost-effective option for plastic cans. The technology is non-contact and can mark both flat and rounded surfaces, making it ideal for lids, can sides or bottoms. With the right type of special ink for plastic, you get high contrast and good adhesion even on smooth or treated surfaces.
Advantages:
Laser provides a permanent marking that cannot be worn away or faded. It works particularly well on light or pigmented plastic cans where the contrast is clear. Because the marking is created by changing the surface layer, no consumables are required – making the solution both environmentally friendly and maintenance-free.
Advantages:
Labelling is used when you need a lot of information in a limited space or want to combine traceability with brand branding. Labels can be placed on the lid, side or around the entire can (wrap-around) and printed in real time with print & apply systems.
Advantages:
To ensure 100% correct labelling, integrated vision systems are recommended. These cameras verify in real time that batch numbers, 2D codes and best-before dates are readable and correctly positioned. The system can also check that the label is correctly positioned and that no incorrect products are moving forward in the chain.
Advantages:
Plastic materials such as HDPE, LDPE, PET and PP have different surface properties, which affect how the marking adheres. The surfaces can be shiny, porous or flexible, which requires careful choice of technology. The most effective marking methods for plastic cans and containers are inkjet marking, laser marking and labelling.
For standard batch number and best-before date marking on plastic jars, we recommend inkjet marking for its flexibility and high speed. For permanent marking on hard plastics or products that require sterilization, laser is the best solution. If the product requires more information, multiple languages or seal labels, labelling is an excellent choice.
Combined with a vision system, you ensure that every label is verified, traceable and in full compliance with pharmaceutical industry requirements.
