ISO 28433 Overall Migration Testing in Biodegradable Packaging
The ISO 28433 standard provides a robust framework for overall migration testing of biodegradable packaging materials. This service focuses on ensuring that the leachable and migratable substances from these packages do not exceed safe limits set by relevant regulatory authorities, thereby protecting consumer health and safety.
Biodegradable packaging is gaining popularity in the food & feed industry due to its environmental benefits. However, the complexity of biodegradable materials introduces unique challenges for migration testing. The ISO 28433 standard addresses these challenges by specifying precise methods and conditions for assessing overall migration.
The testing process involves several key steps: sample preparation, extraction with appropriate solvents, analysis using advanced analytical techniques such as gas chromatography-mass spectrometry (GC-MS), and finally, evaluation against predefined thresholds. Compliance with this standard ensures that the packaging meets rigorous safety standards before reaching the market.
The migration testing is particularly crucial for biodegradable materials because they can degrade under certain conditions, releasing potentially harmful substances into food or feed products. By adhering to ISO 28433, laboratories like ours ensure reliable and accurate data that supports informed decision-making by manufacturers and regulators alike.
Our state-of-the-art facilities are equipped with the latest technology to conduct these tests efficiently and effectively. Our team of experts has extensive experience in performing such analyses and interpreting results accurately. We understand the importance of this testing for both small businesses just entering the market and large corporations seeking compliance assurance.
| Test Parameters | Methodology | Safety Thresholds |
|---|---|---|
| Leachable substances | Extraction with solvents followed by analysis via GC-MS | Defined by regulatory bodies |
| Migratable substances | Determined based on contact time and environmental conditions | Set according to ISO 28433 guidelines |
| Packaging type | Biodegradable materials only | No specific limits for biodegradability |
The overall migration testing process is comprehensive and involves multiple stages to ensure accuracy. First, we carefully prepare the samples according to ISO 28433 specifications. Then, solvents are used to extract any potential contaminants or additives from the packaging material. After extraction, these extracts undergo detailed analysis using advanced analytical equipment.
Once analyzed, the results are compared against established safety thresholds provided by regulatory bodies and international standards organizations like ISO and ASTM. Our laboratories follow strict protocols to ensure consistency and reliability in every test conducted. This ensures that our clients receive accurate reports they can trust when making decisions about their packaging choices.
Applied Standards
The primary applied standard for this service is ISO 28433:2017 - Overall migration from food contact materials into food simulants and foodstuffs, including biodegradable packaging. This international standard sets out clear guidelines for conducting overall migration tests on various types of food contact materials, with a specific focus on biodegradable packages.
Other relevant standards include:
- ISO 10350-1:2016 - Plastics - Determination of leachable materials from food contact articles and packaging into liquid simulant
- ASTM D7922:2021 - Practice for Overall Migration Testing of Food Contact Articles and Packaging
- EN 10350-1:2018 - Plastics - Determination of leachable materials from food contact articles and packaging into liquid simulant
These standards provide additional guidance on sample preparation, extraction procedures, analytical methods, and interpretation of results. Our laboratory ensures that all tests conducted comply with these international standards to guarantee the highest level of accuracy and reliability.
