ASTM F2252/F2252M - Standard Practice for Evaluating Ink or Coating Adhesion to Flexible Packaging Materials Using Tape:
ASTM F2252/F2252M is a standard for evaluating the adhesion of ink or coating on flexible packaging materials using adhesive tape. This standard is important in industries that utilize printing or coating of flexible packaging materials, such as the food and beverage industry, pharmaceutical industry, or consumer goods industry.
The ASTM F2252/F2252M standard evaluates the adhesion of ink or coating to the packaging material by applying and removing adhesive tape. The principle of this method is as follows: A piece of adhesive tape is applied to the printed or coated surface of the packaging material, and then it is removed. The tape can potentially detach the ink or coating, and the amount detached provides an indication of the adhesion quality.
Poor adhesion of ink or coating to the substrate can result in various operational issues. It can affect the readability of printed materials, impacting the product's user interface. It can also influence the functionality of coated materials, potentially reducing the protective qualities of the packaging. Additionally, inadequate adhesion can create potential sources of contamination as detached particles may separate from the packaging.
This practice provides a standardized method for evaluating ink or coating adhesion. However, it is important to note that this standard does not define acceptability criteria. These criteria must be mutually determined by the user and the product manufacturer based on specific requirements and industry regulations.
To improve the validity of the results, it may be beneficial to define and control variables such as the pressure and method of tape application, the speed and angle of tape removal.
This standard is suitable for flexible packaging materials whose surfaces are not damaged by the application and removal of adhesive tape. If the substrate is too delicate for this type of test, alternative adhesion tests should be considered.
