What Ink should I use for Stadium Cups?
Stadium tumbler cups are manufactured using polypropylene. On the bottom of the cup, there is “PP” lettering, or a triangle with the number 5. All these letters indicate polypropylene.
Because of its low surface energy, polypropylene is one of the toughest materials to print. As a result, it is important to pre-treat the material with polypropylene primer, flame treatment, or corona treatment prior to printing. It is important to note that, regardless of the printing method, pre-treat PP plastic cups before printing; otherwise, the ink will not stick to the cup.
The MG Series is the best screen-printing ink for stadium plastic tumbler cups. This ink has high gloss, excellent printability, and screen stability. Additionally, note that the MG ink, when paired with a fast pad printing solvent, is also used for pad printing on stadium cups.
Other excellent screen-printing inks to print on these cups include BX series, EK series, and UVMK series printing inks.
The best pad printing inks for PP plastic cups are the BX Series or the EK Series inks. Both of these inks have a high gloss and are resistant to moisture and chemicals.
For the best ink adhesion on stadium cups printing with the Gyra® high-speed digital cylinder printer, use the 314 UV Inkjet Ink line.
Additionally, we recommend using a neutral ink for UV printing, depending on the print head. For most industrial print heads, such as Ricoh Gen 4, use the Natron 314 Series UV ink. Pair this UV printer ink with PP Primer or the PP3 Digital Primer for long-lasting, vibrant prints.
