Marking on an oil bottle (PET)

oil marking Macsa

PET containers are the most frequently used ones in the industry thanks to their resistance, flexibility and its ease of molding. In this case, a QR code + 1 line of text (Macsa’s website) were marked on an oil bottle (PET). The difficulty of this type of marking is to ensure that the coding is visible and readable on the transparent plastic and on a material that can easily become greasy during the production chain process.

The marking visibility is high because the marking obtained is white on the transparent plastic and on the background, which is yellow in this case. With the appropriate power of the laser (30W), a QR code mark is produced which is perfectly readable with any mobile application.

The last manufacturing process that the product undergoes is coding and marking so that the relevant identification regulations concerning packaged foods or drinks can also be adhered to. In this particular application we can see that the product reference, the time and the expiry date have been marked.

In this case as the bottle top is red, we have achieved a high contrast in white by making a change of colour. In this manner, an indelible mark has been made without damaging the surface in any way.
