UV offset printing on non-absorptive surfaces is getting popular by the days. It gives an ultimate packaging solution for board lamination and decorative printing. The daunting challenge in this segment however remains the availability of right kind of substrate where direct printing can be done without any primer/ treatment.
Uflex Limited has engineered a speciality polyester film F-UVC film which is suitable for direct UV offset printing without requiring any primer/ treatment. The film is available in both bare transparent and metallized variants, where the un-metallized side is used for UV offset printing and UV curing. The metallized polyester film i.e. Flexmetprotect (F-UVC-M) is available in optical density ranging from 1.4 to 2.2. The wide range of optical densities gives choice to customer to use the product for diverse range of applications. The metal bond between the metal and the film is 130-180 gms/25mm.
This film is suitable for direct surface printing without primer/ corona treatment; the lead time is minimum at convertors’ end; and yields excellent print results, high gloss and clarity with high quality resolution for pictures and half tone jobs with good scuffing resistance. It is suitable for high speed machines and is versatile, tear proof and crack resistant and offers excellent smoothness, flatness and ink adhesion.
JK Sharma, AGM, Technical Service and New Product Development (Films), Uflex Limited, said, “Primer coating for rendering the films printable is a cumbersome and time consuming exercise at the convertors’ end. The coating machine is a big capital investment in itself. Therefore with this new innovation by Uflex, the convertors can heave a sigh of relief. Not only does the film increase operational efficiencies of convertors but also restricts their capital expenditure.”
While, Ashok Chaturvedi, chairman and managing director, Uflex Limited, added, “I am happy that the team at Uflex addressed the pain point of convertors by engineering the UV Offset Printable PET Film, which now permits surface printing without any treatment.”
