Pulse Roll Labels launches UV PureFX soft touch varnish

Packaging Solutions

The company believes in making products that create time and simplicity in every print room and is focused on delivering unique and sustainable solutions. Demand for tactile finishes is increasing with brand owners seeking haptic coatings that add a premium touch and feel to a consumer package or label. However, achieving a UV soft touch effect has historically presented challenges for narrow web printers due to the nature of UV free radical curing. With this new development, Pulse Roll Label Products has formulated a product to overcome this and offer an alternative for companies choosing to move away from film or water based coatings.

Testing of the new PureFX soft touch varnish took place at selected label printing sites and yielded results that provided a soft touch effect the company believes is comparable to soft touch lamination films and water based flexo. Demonstrating excellent adhesion, over-printability, press stability, and chemical resistance properties, PureFX is suitable for a range of substrates including coated PE and PP, aluminium foils and paper. The product is also food packaging compliant, formulated for non direct food contact packaging applications, and is particularly well suited for end use markets including cosmetics, beauty, personal care, baby care and beverages. As well as conventional UV flexo printing, the new varnish is also suitable for finishing over digital inks to create a soft, smooth effect.

Simon Windle, technical manager, said: ‘The very nature of UV is that it is hard which is why it is difficult to achieve a soft touch coating with both the haptic properties and the high resistance properties required to protect product packaging from scuffs, rubs and chemicals. When compared to UV curing products, water based coatings can achieve a good soft touch effect but are generally less durable and can be harder to run consistently on press, whilst lamination films are costly and generate more waste. Our research and development team challenged themselves to come up with a high performance UV soft touch varnish that could be a real alternative for companies currently using soft touch lamination films or water based lacquers.’
