ASTM F2250 Practice for Evaluation of Chemical Resistance of Printed Inks and Coatings on Flexible Packaging Materials
Practice for Evaluation of Chemical Resistance of Printed Inks and Coatings on Flexible Packaging Materials
Overview for ASTM F2250:
ASTM F2250 is a practice that describes the procedure for evaluating the ability of an ink, overprint varnish, or coating to withstand chemical exposure. Examples of chemicals that may meet printed inks and coatings include water, alcohol, acid, etc. The specific chemicals, method of choice, and the determination of measurement outcome are left to users to agree upon in joint discussion. Purple Diamond Testing offers this testing as part of our packaging compliance and validation services.
ASTM F2250 is a test method used to determine the chemical resistance of inks, coatings, and printed materials. This standard provides information about the ability of inks to withstand exposure to various chemicals, including solvents, acids, and bases. Chemical resistance is an important characteristic of printed materials as it determines the durability and lifespan of printed products. Inks with poor chemical resistance may be prone to fading, smudging, or peeling when exposed to solvents, acids, or bases. This can result in poor print quality, reduced legibility, and decreased product lifespan.
The test is typically conducted on four types of substrates: paper, plastic film, metal, and glass. The results of the test can be used to assess the chemical resistance of different types of inks and coatings and to identify the most suitable materials for specific applications. Overall, ASTM F2250 is an important standard for ensuring the quality and durability of printed materials in a range of different industries, including packaging, labeling, and signage. By testing the chemical resistance of inks, manufacturers can ensure that printed products will maintain their appearance and legibility even when exposed to harsh chemicals and environmental conditions.
Steps for ASTM F2250
1. Prepare the ink sample and the chemical to be tested according to their respective requirements.
2. Apply a small amount of the chemical on the ink sample and leave it for the specified duration.
3. After the specified time, rinse the ink sample with water and evaluate the resistance of the ink to the chemical using a visual rating scale.
4. Repeat the test with other chemicals to be tested.
5. Record the results indicating the chemicals that the ink is resistant to and the level of resistance.
6. Analyze the data and draw conclusions on the ink’s chemical resistance.
Rationale for ASTM F2250:
Practice for Evaluation of Chemical Resistance of Printed Inks and Coatings on Flexible Packaging Materials. Is intended to see the measure, if any, of the degradation of printed inks and coatings with chemicals that it will or may meet during its lifecycle. ASTM F2250 should not be evaluated for chemicals that are not compatible with the substrate. If there is any chance that your packaged product should or needs to meet certain chemicals such as ink, varnish, or coating, it is highly recommended to inquire about this specific test being done on-site at Purple Diamond. You can send in a sample of your packaged product and our packaging experts will supply the testing for you.
The primary beneficiaries of ASTM F2250 Chemical Resistance of Printed Inks are manufacturers of printed products, ink manufacturers, and end-users of printed materials. ASTM F2250 provides a standardized testing method to evaluate the resistance of printed inks to various chemicals and solvents, which can help manufacturers choose the right ink for their specific application. This can lead to improved product quality, durability, and longevity, and can also help reduce the risk of product failure or safety issues. Ink manufacturers can also benefit from ASTM F2250 by using the testing method to develop and improve their products to meet the specific needs of their customers.

It is an international organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. These standards are used by industries and organizations around the world to ensure quality, safety, and reliability in their products and services. ASTM standards also provide a common language and benchmark for technical activities, research, and development.*
