PP and PPSU Screen Printing Ink for Baby Bottles

Printing on baby bottles requires overcoming two major challenges: ensuring absolute safety and maintaining ink durability through repeated high-temperature sterilization. Inks must bond flawlessly to premium plastics like PP (Polypropylene) and PPSU without peeling off or losing vibrancy.

Our PPSU Ink Series is a premium 2-component solvent-based solution crafted specifically for baby bottles. Not only does it offer unparalleled resistance to boiling water, alcohol, and hand-sweat, but it also streamlines production by requiring zero pre-treatment when printing on PPSU materials.

Frequently Asked Questions

Can this ink withstand high-temperature sterilization?

Yes, absolutely. This 2-component formulation is engineered for extreme durability. It easily passes the 60-minute boiling water test without any blistering, fading, or peeling, making it perfect for baby products.

Do I need to pre-treat the baby bottles before printing?

It depends on the material. For standard PP bottles, flame treatment is necessary to achieve optimal adhesion. However, if you are printing on premium PPSU bottles, our ink bonds perfectly even on untreated surfaces, saving you a processing step.

Technical & Safety Notice: While this ink is RoHS compliant and designed for high durability, products intended for infants and toddlers face strict global safety regulations (such as FDA or EN71). Customers are strongly advised to perform final product testing for chemical migration and adhesion under their specific production conditions before market release.
