An Analysis of Changes in the Harmfulness of the Bottle Packaging Process Depending on the Type of Heat-Shrinkable Film.

This article shows an analysis of selected stages of a machine's life cycle environmental impact in the specific case of machines that package bottles in thermo-shrinkable film. As part of this analysis, laboratory tests were carried out to compare the performance properties of polyethylene films (with and without recycled material). Then, a life cycle assessment (LCA) was carried out within the specified system boundaries using the SimaPro program. Using the ReCiPe 2016 method, differences in the impact of the mass bottle packaging process on the categories human health, ecosystems and resources were determined depending on the shrink film used in the process. These tests showed that the tested batch of film with the addition of recyclates has similar functional properties to traditional ones and can therefore be used in the mass packaging process. The environmental analysis showed that changing the type of film to film with the addition of recyclates results in an almost 70% reduction in the potential negative impact of the process in terms of damage to health and ecosystems, and by 85% in terms of resources.
