Structure Analysis

What is Structure Determination Analysis in Packaging?

Structure determination analysis is a test method that examines in detail the composition, durability and other properties of packaging materials. This analysis is carried out to detect defects that may arise from the manufacturing process of the packaging, to evaluate its interactions with food and other products, and to ensure compliance with national and international regulations.

Major Areas of Analysis:

1. Chemical Structure: The composition and concentration of the chemical substances contained in the material are examined.
2. Mechanical Properties: The durability, flexibility and tear resistance of the packaging are measured.
3. Barrier Properties: Properties such as moisture, oxygen and light permeability are evaluated.
4. Thermal Resistance: The stability and performance of the material against temperature is tested.
5. Migration Potential: The presence and amount of chemicals that can migrate from the packaging to the product is measured.

Objectives of Package Structure Determination Analysis

1. Ensuring Product Safety: To ensure that the packaging does not release any harmful substances in contact with food, medicine or other products.
2. Verifying Material Quality: To determine whether the raw materials used in the production process comply with standards.
3. Ensuring Legal Compliance: Performing the necessary tests to ensure compliance with national and international regulations.
4. Increasing Product Durability: To evaluate the resistance of the packaging to environmental conditions (temperature, humidity, pressure).
5. Gaining Consumer Trust: To increase the reliability of the brand with quality and safe packaging.

Importance of Structure Determination Analysis in Packaging

1. Food and Health Safety: It is imperative to ensure safety in packaging that comes into contact with sensitive products such as food and pharmaceuticals. These analyzes prevent the transfer of harmful chemicals into the product.
2. Sustainability: The use of recyclable and environmentally friendly materials is encouraged. Structure determination analysis verifies the quality of such materials.
3. Regulatory Compliance: Packaging materials comply with European Union regulations such as EU No 10/2011.
4. Consumer Satisfaction: Robust, safe and aesthetic packaging increases consumer satisfaction and enhances brand value.
5. Improving Production Processes: Analysis results can be used to make improvements to packaging production processes.

Test Methods Used in the Analysis of Structure Determination in Packaging

1. FTIR Spectroscopy (Fourier Transform Infrared): Used to analyze chemical structure. Determines polymer types, additives and coating components.
2. Differential Scanning Calorimetry (DSC): Used for measuring thermal properties. Melting point, glass transition temperature and crystal structure are analyzed.
3. Mechanical Tests: Applied to measure mechanical properties such as tensile, tear and impact resistance. The suitability of the packaging for transportation and storage conditions is evaluated.
4. Gas and Water Vapor Permeability Tests: Measures barrier properties. It evaluates the oxygen and moisture transmission that affects the shelf life of the food.
5. Optical Microscopy and SEM (Scanning Electron Microscopy): Provides microscopic examination of the material surface. Defect detection and surface homogeneity analysis are performed.
6. Mass Spectrometry: Allows the components of the material to be analyzed at the molecular level. Volatile and persistent chemical substances are detected.
7. Thermogravimetric Analysis (TGA): Determines the thermal strength and decomposition temperature of the packaging material. Volatile components lost during heat treatment are measured.
