Multilayer angle pieces are used to protect end parts and edges of rolls and packs of various sheet materials, including metals, during transportation and storage. Waxed protective angle pieces applied in metal products packaging may cause allergic reactions of personnel. The paper presents a chemical analysis of cover layer of multilayer waxed protective angle pieces based on cardboard. It was found that the cover layer contains nitrite ions. They can induce allergic itching. Temperature characteristics of the components that make up the cover layer were determined by the method of synchronous thermal analysis. X-ray microanalysis detected carbon, oxygen, calcium and silicon in this layer. IR spectra of the cover layer has revealed the presence of oxygen-and nitrogen-containing functional groups. The research of the multilayer protective angle pieces for metal products packaging has shown nonconformity with the specifications for this type of goods. The cover layer of the angle pieces contains distillate slack wax, nitrogen-bearing corrosion inhibitors. The angle pieces calls for protection measures when packaging metal products.
