Standard Practice for Evaluating Ink or Coating Adhesion to Flexible Packaging Materials Using Tape

SIGNIFICANCE AND USE
3.1 Poor adhesion of ink or coating to the base substrate can impact the readability of printed materials, affect the functionality of coated materials, or create a source of contamination. This practice provides a means for evaluating the adhesion of ink or coating to a flexible packaging material.  
3.2 For purposes of resolving inter-laboratory disagreements, test methods developed from this practice may be improved by defining and controlling the pressure and method of tape application, (for example, using weighted roller), and the speed and angle of tape removal.  
3.3 This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.
SCOPE
1.1 This practice describes a means of evaluating ink or coating adhesion to flexible packaging materials. This practice is intended for use on flexible packaging materials whose surfaces are not damaged by the application and removal of tape.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
