Today, packaging is an integral part of most foods and beverages. However, excessive and just one-time applications of packaging can bring about indisputable environmental impacts in the form of large amounts of waste generated. If we want to monitor the environmental impacts of packaging materials, it is advisable to assess them in a complex way including not only the specific packaging but also specific products. No universal methodology currently exists that would enable this type of complex assessment regarding the environmental impacts of packaging in relation to particular products. Therefore, the aim of our study was to develop and test a Package-to-Product (PtP) indicator. For this purpose, the life cycle assessment (LCA) was employed to analyse four selected products considering different life cycle stages of packaging and their impacts on the climate change category. The results of the study confirm that the values of the PtP indicator significantly differ for various products, thus emphasising the need to establish a uniform methodology for individual product groups, such as meat, dairy and vegetable products or beverages. The application of this indicator, however, enables a clear impact assessment of different packaging materials and allows the packaging manufacturers to reduce their overall environmental impacts.
