The main objective of any surface treatment method is to increase the energy of film’s surface for improving wet-out and adhesion of coatings, inks and adhesives used in converting process. Surface treatment of films/substrates may involve several techniques like corona discharge; flame treatment; priming and chemical etching. This could be an expensive proposition besides increasing the lead time.
To alleviate this problem, Flex Films has launched a special polyester film, F-PDP with modified surface on one side while the other side remaining untreated. This film is digitally printable without any need for priming/ coating.
This film can be directly printed without requiring printing plates/ cylinders as in the case of conventional printing process. Additionally the film demonstrates good transparency; optical clarity; excellent machinability and dimensional stability besides offering excellent flatness and agile handling properties.
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.
There are a multitude of benefits associated with digitally printable PET films:
• Suitable for small run jobs particularly for new launch or re-launch of products;
• Minimizes lead time at the converter’s end because no primer/ coating is required;
• Gives excellent print results with high quality resolution for pictures and half-tone jobs using primary colors i.e. C,M,Y,K and White giving results at par with conventional printing even on transparent substrates;
• Option of special colors like Gold, Silver etc. can further impart depth in printing;
