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.

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.

This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.

1. 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 SI units are to be regarded as standard. The values given in parentheses are for information only.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
