Identification of polymers and analysis of labeling symbols on non-alcoholic beverage packaging

Abstract

Packaging for non-alcoholic drinks is an important category of plastic products, with direct implications for food safety, environmental protection, and the efficiency of recycling systems. In the context of the transition to a circular economy, proper management of this packaging becomes an essential objective, contributing to the reduction of waste generation and the valorization of resources through recycling. The labeling standardizing of plastic materials, including Resin Identification Codes (RIC) and recycling symbols, represents a fundamental tool both for efficient selective collection and for correctly informing consumers. In this regard, the present study aims to identify the polymers used in soft drink packaging marketed in the Republic of Moldova and to analyze the uniformity of labeling symbols, in relation to current requirements for sustainable waste management.
