Greenflex EVA FL55
Versalis EVA Greenflex® FL55 is a specialty ethylene-vinyl acetate (EVA) copolymer developed by Versalis S.p.A. (ENI, Italy) for co-extrusion blown and cast film, multi-layer lamination, stretch film, and high-performance food packaging. With 19% vinyl acetate, MFI 2.5 g/10 min, density 0.941 g/cm³, haze 1.5%, gloss 85%, dart impact 420 g, and brittleness < –80°C, FL55 delivers a rare combination of low fisheye purity, superior flexibility, optical clarity, and low-temperature sealability.
Greenflex FL55 is engineered for converters and packaging manufacturers who demand crystal-clear, flexible, and strong multi-layer films with reliable tie-layer performance and food-contact compliance. Its balanced polarity and flow properties make it the ideal choice for co-extrusion, lamination, and flexible food packaging operations across India’s major film and packaging clusters.
Functional Features & Technical Authority

Then the question arises: where’s the content? Not there yet? That’s not so bad, there’s dummy copy to the rescue. But worse, what if the fish doesn’t fit in the can, the foot’s to big for the boot? Or to small? To short sentences, to many headings, images too large for the proposed design, or too small, or they fit in but it looks iffy for reasons.
A client that’s unhappy for a reason is a problem, a client that’s unhappy though he or her can’t quite put a finger on it is worse. Chances are there wasn’t collaboration, communication, and checkpoints, there wasn’t a process agreed upon or specified with the granularity required. It’s content strategy gone awry right from the start. If that’s what you think how bout the other way around? How can you evaluate content without design? No typography, no colors, no layout, no styles, all those things that convey the important signals that go beyond the mere textual, hierarchies of information, weight, emphasis, oblique stresses, priorities, all those subtle cues that also have visual and emotional appeal to the reader.
