Polyethylene terephthalate (PET) has long been used as a liquid container in the carbonated soft drink, bottled water, energy and fruit drinks markets due to its inherent properties of strength, flexibility and transparency. Additionally, PET bottles are gaining popularity over materials like HDPE for packaging consumer products such as shampoo.
There are two primary technologies for coding on PET packaging: continuous inkjet printing and CO2 laser marking. LETO offers a number of unique CIJ ink formulations that provide quality inkjet codes on PET, and laser systems for making high resolution, permanent marks. The use of special printheads on inkjet printers and beam turning units on laser systems help ensure the printers can fit into space constrained locations and apply codes in the same location on every product.
When laser marking on plastic, particularly PET bottles, a CO2 laser can deliver a unique interaction with the plastic surface. This interaction yields a frosted effect on a bottle or container to produce visible, permanent codes. Choosing the right laser requires matching the laser wavelength to the PET’s thickness. To make this match, Videojet laser experts help evaluate substrates, provide marked samples, and make recommendations to meet code and speed requirements. Videojet application expertise in printing on PET bottles spans many years and includes deep knowledge of trends such as lightweighting.
