India-based Uflex has developed a new digitally printable polyester (PET) film, F-PDP, for use in various flexible packaging applications.
The newly launched special F-PDP film, which features a modified surface on one side and an untreated surface on the other, is digitally printable and does not need priming or coating.
Unlike traditional printing process, the newly developed film can be directly printed without requiring printing plates or cylinders.
Uflex technical service and new product development (films) AGM J K Sharma said: “Coating / priming or surface treatment of a film for enhancing its ink adhesion properties is a time-consuming process needless to mention the additional costs that are involved.
“Our special F-PDP film is a perfect delight for convertors at a time when the entire world is moving towards Just in Time (JIT) deliveries minimising inventories. Polyester film suitable for direct digital printing has been a need gap.
"Other inherent advantages of polyester film, like the ability to render excellent print results, being tear-proof and crack-resistant, make it a suitable and preferred media for digital printing.
“Additionally polyester is able to withstand high temperatures and remains stable and inert to many chemicals further enhancing its suitability for convertors.”
Certified by Rochester Institute of Technology for digital printing by HP Indigo commercial and sheet fed presses, F-PDP has improved transparency, optical clarity, enhanced machinability and dimensional stability, flatness and agile handling properties.
The company also noted that depending upon the requirements of the converting process, the F-PDP film can be manufactured in various thicknesses ranging from 10µ to 50µ.
