ASTM F2252-13

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2252 − 03 (Reapproved 2008) F2252 − 13
Standard Practice for
Evaluating Ink or Coating Adhesion to Flexible Packaging
1
Materials Using Tape
This standard is issued under the fixed designation F2252; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
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 either SI units or inch-pound units are to be regarded separately as standard. The values given in
parentheses are for information only.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.

3. 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.
4. Apparatus
3
4.1 3M #610 or Sellotape office adhesive tape is commonly used for this procedure, typically 19 to 25 mm ( ⁄4 to 1 in.) wide.
Whichever tape is chosen should be agreed upon by customer and supplier.
4.1.1 Manufacturers storage and shelf-life recommendations should be followed or acceptability determined through real-time
aging and laboratory tests. Test Method D3330/D3330M gives guidance on testing. Again, as stated in 3.3, acceptability criteria
is a matter of agreement between customer and supplier.
5. Sampling
5.1 The number of samples tested should be adequate to be predictive of performance. Caution should be taken when
eliminating samples with defects as this can bias results.
5.2 See Practice D1898 for guidance on standard sampling practices.

6. Conditioning
6.1 Conditioning of the samples will depend on the material under evaluation. If conditioning before testing is appropriate,
normal, and desirable, then condition therefer to E171 test specimens at 23 6 2°C (73.4 6 3.6°F) and 50 6 5 % RH for not less
than 24 h prior to test.for guidance.
6.2 Before testing catalyzed or cured inks or coatings, or both, ensure that the samples have been exposed to the appropriate
conditions for sufficient time to allow complete cure.
6.3 See Practice D4332 for guidance on conditioning practices.
7. Procedure
7.1 Lay sample to be tested on a flat surface. Sample should lay flat and smooth without wrinkles, creases, or folds.
7.2 Cut a piece of tape long enough to cover the printed or coated area of interest on the sample. F
