Conclusions

What this means to converters?

� Frequent design changes

� New product design cycle times continue to shrink.

� Costs need to come down.

� Color match more critical globally.

� Environmentally friendlier solutions.

Why Flexo …

Challenges facing CPGs:

Run lengths are getting shorter

� Marketing demands for frequent graphics changes

� Cost, Environmental pressures on Packaging

� Upward trends in the costs of films and resins

� Substrates-Getting Thinner & Extensible

� JIT supplies to reduce inventories

� “SKU proliferation” requires increasingly different labels .

Flexo – For Fastest Turnaround time

Flexo – For Versatility

The biggest benefit of Flexo is its great flexibility. It prints on virtually any substrate, being it smooth or rough, having absorbing or non-absorbing properties, using a variety of inks, water-based, solvent-based or UV.

It is best-suited for printing on a wide range of clear and opaque substrates such as Paper, Polyethylenes, Laminates, Labelstocks, Foils, TetraPaks, etc. It is the only process capable of consistently printing with perfect registration on thin, extensible films right down to 25 micron PE.

Flexo for Costs…

Overall economics better with Flexo due to -

� Marginal benefits in ink, plate, equipment costs

� Higher Press-speed – Entry-level presses at 400 m/m, 600 m/m presses already in!

� Reduced set-up and running waste – web length half that of Gravure.

� Drier-length typically half that of gravure. Typically gas-fired or electrically-heated for PE. Lower power-consumption.

� Lower VOCs due to completely enclosed doctor-blade, closed loop inking system. Minimal solvent loss due to evaporation.

DuPont™ Cyrel® DigiFlow is a digital workflow enhancement designed to expand the capabilities of digital Cyrel® and digital Cyrel® FAST. The DigiFlow exposure system enables 1:1 image reproduction when a screened solid is beneficial, and with the flip of a switch returns to the standard digital exposure workflow whenever that is the preferred solution.

Features & Benefits- Optimizes performance of solid - No additional platemaking steps

screening programs such as Groovy or Microcell - Maximum workflow flexibility- Improved solid ink densities - Minimal consumable cost- Increased color gamut - No environmental impact- Easily integrated into existing workflows- Compatible with all CDI Versions & HD Flexo

Conclusions

Hazards of Chrome

•Chromium compounds are considered highly toxic to humans.

•Chromium (VI), or hexachrome, can cause ulcers of the skin, irritation of the nasal mucosa, and irritation of the gastrointestinal tract, and adverse effects in the kidneys and liver.

•Based on animal and human studies, chromium (VI) and its compounds should be considered probable carcinogens in humans exposed by inhalation

THE CHROMIUM CONNECTION

Chromium (III) occurs naturally in the environment.

• Chromium (VI) is generally produced by industrial processes, and used in such industries as pigment manufacturing, leather tanning, wood treatmentand chrome plating.

• The primary use for chromium compounds containing chromium (VI) is in the metal finishing industry for both decorative and functional purposes.

• Chromium is often chosen as a surface finish because it possesses a low coefficient of friction, high hardness, good corrosion resistance, high heat resistance and anti-galling properties. Due to its toxicity and suspected carcinogenicity, however, chromium is heavily regulated for the protection of human health and of the environment.

• These regulatory requirements, as well as the growing awareness among metal platers regarding the health effects of chromium exposure, have led to a search for acceptable alternatives to using chromium in theelectroplating industry.
