Printing on EVA foam materials, such as Bogg bags, requires the right inks and pre-treatment based on the chosen printing method. To achieve long-lasting, vibrant results, here is a step-by-step guide tailored to this popular application.

There are various methods for printing on Bogg bags, including pad printing, screen printing, and UV inkjet printing. Both screen and pad printing utilize XG Series ink. In contrast, digital printing requires either neutral or flexible UV inks. It’s essential to match the choice of UV printing ink with the correct printhead. For industrial printheads, such as Ricoh Gen 5 and 6, we recommend the Natron® 314 UV ink.

Surface pre-treament/ Printing preparation:

Bogg bags are made from EVA material, which is challenging to print on. As a result, a pretreatment is required for permanent ink adhesion. We recommend pre-treating the EVA surface with our Natron® PP Primer or our Natron® P53 Primer to ensure superior adhesion. As a product, the PP adhesive promoter increases the surface energy of the substrate allowing the ink to bond permanently to the surface. The PP and P53 digital primers can also be applied to other materials like polypropylene, polyethylene, non-silicone rubber, and nylons that have a thermoplastic polyurethane (TPU) coating.

Printing on Bogg baggs (EVA material):

Once primed, the Bogg bag is ready for printing. The following supplies are required for screen printing:

Mix the ink with 5% hardener, then add 10% solvent into the ink. Mix the three components together and print. Use heat to post-cure the prints.

Pad printing, on the other hand, while it uses the same ink and hardener, the TM3 solvent is needed. The TM3 is a medium-speed pad printing solvent.

Once the prints are cured, they will resist wear and tear, water, and are flexible. Additionally, they are resistant to outdoor conditions and weather elements. Lastly, the XG Series like all Natron inks are formulated with sustainability, compliance, and use hand selected non-toxic materials. This combination guarantees durability without compromising color quality.

Other XG Series applications:

The Natron® XG Series ink a specialized 1- or 2-component ink with excellent adhesion to foam stress reliever balls, EVA foam items, apparel, and rubber-like materials.The ink’s unique flexibility, high gloss, and opacity make it the ideal choice for rubberized and soft-touch items.

Available in 22 standard, 2 metallic, 7 neon, and CMYK 4-color process shades. All colors are intermixable to create new colors. Custom color matches available within hours upon request.
