Compared to other packaging materials, the life cycle of plastics shows more benefits in areas like energy and water use, solid waste, and greenhouse gas emissions. Another major benefit of thermoformed plastic packaging is that it is a form of light weighting or source reduction. A custom plastic blister pack, for example, is much more lightweight than a box. Plastic packaging can do more with less than other packaging solutions. It takes less the resources to create the package and less effort to create and transport because thin gauge plastic is so lightweight. Lighter packaging solutions like thermoformed trays, custom clamshells, and plastic blister packaging will result in less fuel used in shipping and take much less energy to produce.
