The quality control tests for the determination of the type and additives of plastic packaging materials and especially in films include tests with FTIR devices. Qualitative and quantitative determination of material is done by using FTIR or automatic titrator devices in both raw material and final product.

In the packaging industry, the most suitable spectroscopic method, which is the most widely used area for plastics, is infrared method. The FTIR spectrum device is used to detect organic compounds. The content of inorganic materials is determined by X-Ray spectrophotometer directly on the plate prepared from polymer.

FTIR stands for Fourier Transform Infrared Spectroscopy, which means Fourier transform infrared spectroscopy. FTIR spectroscopy is a kind of infrared vibration spectroscopy. With this method, molecular bond structures are analyzed and whether the organic compounds in the solid, liquid, gas or solution state are the same and the state and bonding sites of the bonds in the structure are determined.

In the infrared method, the energy required for the bending, shaking, shaking, bending and similar movements of chemical bonds in molecules is absorbed from the electromagnetic energy of infrared rays.

FTIR spectroscopy method is a very important method in quality control studies, material tests and academic research and studies. This method is also used in the analysis of coating materials such as textile, paint, foam and glaze.

New developments have been made in the FTIR method in recent years and the applicability of this method has increased more. Today, it is almost impossible to analyze complex plastic structures and materials without this method.

Within the scope of package analysis in advanced laboratories, studies are carried out to determine the structure for each of the packaging materials and materials by FTIR spectroscopy method. These analyzes are based on standards and test methods published by national and international organizations.
