Going Green

In response to an increasing focus upon resource sustainability and caring for the environment, there is a growing pressure on the packaging industry not only to reduce packaging volume but to consider, where possible, the use of biodegradable, carbon free and recyclable materials.

There are an emerging range of packaging materials, derived from organic material rather than oil, which do not compromise on performance. In particular, an exciting range of biodegradable films, initially developed for the food sector but which, in the long term, are predicted to be in demand by a wider range of industries.

The packaging industry is a major user of plastic because it is relatively inexpensive, flexible, lightweight, strong (with a high strength to density ratio), hygienic, non-rusting and a good insulator of heat. Although thermoplastic can be melted, recycled or greatly reduced in size by compression, it will not degrade in soil and will, therefore, remain intact indefinitely in landfill.

Growing pressure from the European Community (EC) Directive and landfill taxation has lead to an increase in recycling initiatives and the development of starch-based substitutes for both plastic and other products.

In terms of the packaging industry, the demand for biodegradable packaging has risen within niche areas such as medical, organic and other fresh food sectors as manufacturers seek to extend brand values and product lifecycles.
