………………
Mass of packaging per
person in:
• UK – 147 kg/year
• Germany – 158 kg/year
• Netherlands – 172 kg/year
• France – 162 kg/year
•China-22 kg/year
•India- 15 kg/year

5. Increasing packaging
Single-serve packaging and ready meals are convenient
for consumers, but use more packaging.

6. Packaging and lifestyle
What is the relationship between the amount of
packaging and lifestyle?

12. Sustainable development
A plan for the development of communities that
balances the importance of a vibrant economy
and sustainability.
The United Nations
Environment and Development
Programme states that human
well-being is central to its
efforts to promote sustainable
development.

13. Weak sustainability
The three elements of sustainable development – the
environment, society and the economy – are competing
interests. The point where they come together represents
sustainable development.
environment
society economy

14. Weak sustainability
This model accepts that many aspects of development
serve the economy, society or the environment alone. It
suggests that technology can be a substitute for a
damaged environment.
environment
society economy

15. Strong sustainability
The environmental element of sustainable development
is viewed as the common ground where society and the
economy interact and develop.

16. Strong sustainability
Development cannot damage the environment; a healthy
environment is fundamental to a just and fair society and
a vibrant economy – now and in the future.

17. Designing for weak sustainability
Consider the economic, social and environmental
strengths and weaknesses of their designs, but
compromise to minimise potential environmental harm.
Can you name a
packaging material
that achieves weak
sustainability?

18. Designing for strong
sustainability
Consider the economic, social and environmental
strengths and weaknesses of their designs, but do not
compromise and achieve environmental protection as a
design priority.
Can you name a
packaging material
that achieves
strong
sustainability?

19. Reduction of VOCs emitted to
the atmosphere

20. Reduced potential for
discharging toxic substances

21. Reduces the potential for fire and
explosion, thereby eliminating
some of the costly provisions and
regulations required for the
flammable solvents and inks

22. Reduces the amount of hazardous
wastes

23. Improves the working conditions in
the plant

24. Brings the firms into
compliance with almost every
regulations

25. Advantages of Water-based Inks
•Non-toxic and non-flammable
•Increased life of stereo and photopolymer
plates
•Sharper printings
•Low residual print odor, or none at all
•Less maintenance costs

26. Advantages of Water-based
Inks
• Less pigment choice
• Inferior ink gloss
• Slow drying, with consequentially
higher energy costs and slower
production runs
• Problems with multicolor printing due
to substrate distortion from water
absorption
• No Evaporation

o Milk Carton and Preprint Corrugated
Board(PPCB)

30. Indian Printing Market with Water
Based Inks

31. Water Based Gravure Inks Market
Facts:
Not Familiar with water based
New Field Market
Need High Performance resins
Depending on application NOT
regulation
Possibilities of substituting of Solvent
based

32. Major New Developments Required to enhance
the potential of w/b ink attempts
o Decreasing the amount of inks printed per square
meter of substrate
o Designing the binder in such a way that it
releases the water faster from the ink film
o Modifying the design of the printing press
o Research in pigment development to increase
color choice
o Research in the field of hybrid and cross-linking
resins that are initially water-soluble but change
to insoluble after printing
