Inc or Coating Adhesion to Flexible Packaging Materials Using Tape
ASTM F2252 is a standard test method used to evaluate the adhesion of inks and coatings on flexible packaging materials using pressure-sensitive tape. This test helps determine how well printed or coated surfaces will withstand handling, transportation, and real-world use without smearing, flaking, or delaminating. While not exclusively designed for cryogenic applications, it is often applied in those contexts to assess label and print durability under extreme conditions, where adhesion performance becomes even more critical.
How is ASTM F2252 Performed
The test is performed by applying a standardized pressure-sensitive tape to the printed or coated surface under controlled conditions. The tape is then removed at a consistent angle and speed, and the surface is evaluated for any ink or coating removal. The amount of material transferred to the tape or removed from the substrate is assessed—typically visually—and can be rated qualitatively or quantitatively depending on the requirements. Proper surface preparation, consistent tape application pressure, and environmental controls are essential to ensure repeatable and meaningful results.
ASTM F2252 is particularly valuable for medical device and pharmaceutical packaging, where print integrity is essential for traceability, regulatory compliance, and usability. Poor adhesion can lead to loss of critical information such as lot numbers or instructions for use. When used in conjunction with other environmental conditioning (e.g., sterilization, aging, or low-temperature exposure), this method provides insight into how inks and coatings will perform throughout the product lifecycle.
Frequently Asked Questions
How is acceptance criteria determined for ASTM F2252?
Acceptance criteria are not determined by the practice. It should be an agreement between customer and supplier.
What is the recommended sample size for ASTM F2252?
There is no recommended sample size. What is typical for attribute testing is N = 60.
What kind of tape is used for testing for ASTM F2252?
Example tapes from the practice are 3M Scotch 600, 681, 810, or 893. 3M 616 Lithographers. Nitto P-99. Sellotape. Tesa 60802 or 64204. With that being said, any requested tape can be used.
