5. Conclusion

Lightweight products are gaining ground in the field of disposable food packaging. Three factors are combining to drive this trend:

• an environmental factor ;

• an economic factor;

• easy access to technology.

In today's environmental context, manufacturers are under increasing pressure to reduce their carbon footprint. Lifecycle analyses now provide a powerful tool for assessing a product's overall carbon footprint, throughout its life cycle (raw material transport, manufacturing, transport, storage, consumption, landfill treatment, incineration). Mass gain, associated with pot shape, is one of the key factors whose impact on carbon performance can be measured.

With unchanged productivity – productivity is now measured...
