Uflex launches HP Indigo certified F-PDP

March 21, 2017 - India

A special polyester film with modified surface on one side and the other side untreated is all set to simplify digital printing since it is digitally printable without the need for priming/coating. The film unveiled by India's largest multinational flexible packaging materials and solution company Uflex also demonstrates good transparency and optical clarity.
The film called F-PDP also has excellent machinability and dimensional stability besides offering excellent flatness and agile handling properties. It can be directly printed without requiring printing plates/ cylinders as in the case of conventional printing process. 
The polyester (PET) film F-PDP has been certified by Rochester Institute of Technology for digital printing by HP Indigo commercial and sheet fed presses. 
The benefits associated with digitally printable PET films include their suitability for small run jobs particularly for new launch or re-launch of products, minimising of lead time at the converter's end, excellent print results with high quality resolution for pictures and half-tone jobs using primary colors even on transparent substrates and availability of option of special colors like gold, silver etc. 
"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. 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," J K Sharma, AGM, technical service and new product development (films), Uflex Limited, said. 
"Depending upon the requirements of the ensuing converting process, we can offer F-PDP film in various thicknesses ranging from 10-50 microns. The demand for this substrate is quite encouraging both in India as well as overseas as a result of which we are manufacturing it at all our plants i.e. India, UAE, Poland, Egypt, Mexico and US, " Pramod Sirsamkar, president - technical & new product development (films) said.
Digital printing is highly preferred in current times due to its ability to offer ultimate solutions for flexible packaging, labels and decorative printing segments. The converting industry for long has been grappling with restricted availability of the right type of substrate supporting direct digital printing without prior priming /coating or surface treatment.
Surface treatment increases the energy of film's surface for improving wet-out and adhesion of coatings, inks and adhesives used in converting process. Surface treatment may involve several techniques like corona discharge, flame treatment, priming and chemical etching. These processes are expensive and also increase the lead time. (SV)
