1、Designation: F 2252 03 (Reapproved 2008)Standard Practice forEvaluating Ink or Coating Adhesion to Flexible PackagingMaterials Using Tape1This standard is issued under the fixed designation F 2252; the number immediately following the designation indicates the year oforiginal adoption or, in the cas
2、e of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes a means of evaluating ink orcoating adhesion to flexible packaging
3、 materials. This practiceis intended for use on flexible packaging materials whosesurfaces are not damaged by the application and removal oftape.1.2 The values stated in SI units are to be regarded asstandard.

Significance and Use3.1 Poor adhesion of ink or coating to the base substrate canimpact
5、the readability of printed materials, affect the function-ality of coated materials, or create a source of contamination.This practice provides a means for evaluating the adhesion ofink or coating to a flexible packaging material.3.2 For purposes of resolving inter-laboratory disagree-ments, test me
6、thods developed from this practice may beimproved by defining and controlling the pressure and methodof tape application, (for example, using weighted roller), andthe speed and angle of tape removal.3.3 This practice does not address acceptability criteria.These need to be jointly determined by the
7、user and producerof the product.4. Apparatus4.1 3M #610 or Sellotape office adhesive tape is commonlyused for this procedure, typically 19 to 25 mm (34 to 1 in.)wide. Whichever tape is chosen should be agreed upon bycustomer and supplier.4.1.1 Manufacturers storage and shelf-life recommenda-tions sh
8、ould be followed or acceptability determined throughreal-time aging and laboratory tests. Test Method D 3330/D 3330M gives guidance on testing. Again, as stated in 3.3,acceptability criteria is a matter of agreement between cus-tomer and supplier.5. Sampling5.1 The number of samples tested should be
9、 adequate to bepredictive of performance. Caution should be taken wheneliminating samples with defects as this can bias results.5.2 See Practice D 1898 for guidance on standard samplingpractices.6. Conditioning6.1 Conditioning of the samples will depend on the materialunder evaluation. If conditioni
10、ng before testing is appropriate,normal, and desirable, then condition the test specimens at 236 2C (73.4 6 3.6F) and 50 6 5 % RH for not less than 24h prior to test.6.2 Before testing catalyzed or cured inks or coatings, orboth, ensure that the samples have been exposed to theappropriate conditions
11、 for sufficient time to allow completecure.6.3 See Practice D 4332 for guidance on conditioning prac-tices.1This practice is under the jurisdiction of ASTM Committee F02 on FlexibleBarrier Packaging and is the direct responsibility of Subcommittee F02.20 onPhysical Properties.Current edition approve

Procedure7.1 Lay sample to be tested on a flat surface. Sample shouldlay flat and smooth without wrinkles, creases,
14、 or folds.7.2 Cut a piece of tape long enough to cover the printed orcoated area of interest on the sample. For large areas it may beeasier to work with several shorter pieces of tape. Handlingapplication and removal of tape is simpler when length of tapedoes not exceed 12 in.7.3 Apply tape to sampl
15、e using a smooth even motionwithout wrinkling tape or sample. Run thumb or forefingeralong tape to make sure it is fully adhered, without any bubblesin surface.7.4 Hold sample flat to surface with one hand, use otherhand to peel back tape at an angle of approximately 120 to150. Lift tape, pulling ba
16、ck with an even, moderate motion.Typically 305 to 460 mm (12 to 18 in.) per second.NOTE 1Varying the amount of time after tape is applied may affectthe results.7.5 Examine the test sample for missing print or coatinggaps.7.6 Examine tape for any ink or coating removed from thetest sample. As an aid
17、for visual inspection reference standardsmay be created and used to determine degree of transfer.7.7 Record results. Characterize the degree of adhesionusing mutually agreed upon references. If multiple colors ofink are present, results may vary by color and may be reportedthat way. This is a subjec
18、tive test and operator training iscrucial for consistent reporting of test results.8.
