In the food industry, various materials are used for packaging, including polymeric ones. Containers made from them have a number of advantages and conveniences both during transportation and in the process of storing packaged products, but they create significant risks of environmental pollution. It is disposable and needs to be disposed of or recycled after use.Packaging food products in containers made from secondary raw materials allows solving a number of environmental problems and reducing dependence on disposable containers. The introduction of innovative technologies using polymer waste of polyethylene terephthalate as a raw material for manufacturing, for example, bottles, also has economic feasibility.Polymer packaging is a potential source of pollution, harmful substances can migrate from it into food products, and therefore research is needed on the safety of using polymer materials made from secondary raw materials for packaging food products with regard to the migration of toxic components from them. Milk, alcoholic and low-alcohol products, oil, drinking water, vinegar, etc. are packed in polyethylene terephthalate bottles.The analysis of research and publications showed that special attention is paid to the safety of the use of secondary polymer containers in the food industry. To determine its compliance with food safety requirements, organoleptic and sanitary-chemical studies are performed, the level of migration of chemicals into the studied environment is monitored. The possibility of safe use of bottles made of secondary polyethylene terephthalate for packaging water and vegetable oil was investigated. But research on the migration of toxic components from bottles to other food environments is needed.The purpose of the article is to study the migration of toxic substances from bottles made from secondary raw materials into drinking pasteurized cow's milk, water-alcohol solutions, aqueous solutions of acetic and lactic acid of various concentrations.The article presents the results of a study of the safety of using bottles made entirely of secondary polyethylene tereph-thalate for packaging milk with a 2.5% fat content, alcohol-containing products with an alcohol content of 5% and 40%, as well as aqueous solutions of acetic and lactic acid of various concentrations. The determined indicators of migration of acet-aldehyde, acetone, butanol, isopropanol, methanol, ethylbenzene, dimethyl terephthalate and other toxic components into the studied environment comply with the established hygienic standards and do not exceed the permissible amount of migration. Bottles made entirely from recycled materials meet the requirements for containers. which is in contact with food products, and can be recommended for packaging the studied types of products
