Increasing packaging

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

Why water-based ink formulations ?

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.

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

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

Strong sustainability

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

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.

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?

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?

Reduction of VOCs emitted to the atmosphere

Reduced potential for discharging toxic substances

Reduces the potential for fire and explosion, thereby eliminating

some of the costly provisions and regulations required for the

flammable solvents and inks

Reduces the amount of hazardous wastes

Improves the working conditions in the plant

Brings the firms into compliance with almost every

regulations

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

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

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 presso Research in pigment development to increase

color choiceo Research in the field of hybrid and cross-linking

resins that are initially water-soluble but change to insoluble after printing
