EN 15386:2007 (E) 4 1 Scope This standard
15、 specifies a method for the determination of the print adhesion on flexible laminate and plastic tubes. It is applicable to flexible laminate and plastic tubes used for packing pharmaceutical, cosmetic, hygiene, food and other household products. 2 Principle The adhesive tape test serves to gauge th
16、e adhesion properties of printing ink films on flexible laminate and plastic tubes. The printing ink film is tested by rapidly tearing-off a previously applied adhesive tape. After the tape has been torn off, the divided surfaces are judged by pre-established criteria. 3 Apparatus An adhesive tape o
17、f commercial quality equipped with an upper surface made of tear-proof plastic and a pressure sensitive adhesive coating, of which the adhesive power is: minimum 5 N/25 mm and maximum 7 N/25 mm, tested according to Annex A against a glass testing surface. 4 Procedure Place the printed sample on an e
18、ven surface. Apply the adhesive tape on the sample and press it on manually across the length of the decoration. It is important that there is full contact with the surface over the whole area and that no air bubbles remain between adhesive tape and sample surface. Approximately 10 s to 30 s after p
19、ressing-on, manually tear off the free end of the adhesive tape in one go from the surface at an angle of about 150 . Examine the divided surfaces (printing surface and reverse side of the adhesive tape). Analyse the divided surfaces according to Table 1. Table 1 Evaluation of test results Appearanc
20、e of the divided surfaces Assessment Category No damage of the print or the printing material, pure adhesion fracture Adhesive tape resistant Pass Damage to the print and printing material. Not adhesive tape resistant Fail The severity of the failure mode should be defined between customer and suppl
21、ier. EN 15386:2007 (E) 5 5 Test report If not otherwise agreed between supplier and customer the test report shall contain the following information: a) Reference to this standard and if necessary a specification for the method of sampling and acceptance of the batch, b) Complete identification of t
22、he batch and of the tubes checked, c) Date of printing, d) Number of tubes checked, e) Number of defects, f) Test result, g) All factors which could have affected the results or all operating details not specified in this standard, h) Date, place of test and name of tester.

23、 A (normative) Peel adhesion (180 ) at 300 mm/min A.1 Scope This test method is designed to quantify the permanence of adhesion or peel ability of self-adhesive, pressure sensitive materials A.2 Definition Peel adhesion is defined as the force required to remove pressure sensitive coated material, w
24、hich has been applied to a standard test plate under specified conditions from the plate at a specified angle and speed. Adhesion is measured at 20 min after the application and 24 h after application, the latter being considered as the ultimate adhesion. A.3 Apparatus and reagents A tensile tester
25、or similar machine, capable of peeling a laminate through an angle of 180 with a jaw separation rate of 300 mm/min with an accuracy of 2 %. Test plates made of float glass or similar plate glass. A 2 kg roller. NOTE 1 The standard FINAT test roller is recommended for this purpose1. The test plates s
26、hall be thoroughly cleaned so that no trace of adhesive, grease, silicone or moisture is left on the surface. The following solvents can be used to clean the test plates: Diacetone alcohol non-residual, technical grade or better Methyl Ethyl Ketone (MEK) Acetone Methanol 95 % n-Heptane Ethyl Acetate
27、 1Information on how to obtain a FINAT hand roller is available from FINAT,Laan Copes van Cattenburch 79, 2585 EW The Hague, Netherlands, e-mail: URL: 1. The FINAT test roller is an example of a suitable product available commercially. This information is given for the convenience of users of this
28、European Standard and does not constitute an endorsement by CEN of this product. EN 15386:2007 (E) 7 The cleaning material shall be absorbent, e.g. surgical gauze, cotton wool or tissue. To be suitable, materials shall be lint-free during use, absorbent, contain no additives that are soluble in the
29、solvents listed above, and made exclusively from virgin materials. Dispense one of the solvents listed above onto the panel, wiping it to dryness with fresh absorbent cleaning material. Repeat for a total of three washes with the solvent. Final wipe shall be with MEK or acetone. Alternative methods
30、that remove contamination properly can be adopted, e.g. ultrasonic cleaning. Prior to use, the cleaned plates should be left for 4 hours under standard test conditions. Care should be taken to handle clean plates by the edge only. Alternative surfaces to plate glass can be used such as stainless ste
31、el aluminium or polyester film, but this must be clearly stated alongside the results. If adhesion values are required when paper tear has occurred, then this test can be conducted at lower jaw separation rates quoting the latter against the results. NOTE 2 Conversion 1 Kgf = 9,81 N. A.4 Test Pieces
32、 These should be strips taken from a representative sample of material. The strips should be 25 mm wide and have a minimum length of 175 mm in the machine direction. The cuts should be clean and straight. At least three strips should be taken from each material sample. A.5 Conditioning Temperature 2
33、3 C 2 C, 50 % RH 5% RH. The test sample or test strips should be conditioned for not less than 4 h before testing. Figure A.1 Test strips A.6 Procedure Remove the backing material from each strip and place the adhesive coated facing material, adhesive side down, on to a clean test plate using light
34、finger pressure. Roll twice in each direction with the roller at a speed of approximately 10 mm/s to obtain intimate contact between the adhesive mass and the surface. After applying the strips to the test plate, leave for a period of 20 min before testing. Repeat the procedure with a second set of
35、strips and leave for a period of 24 h before testing. Fix the test plate and strip in the machine so that the angle of peel is 180 . Set the machine at 300 mm/min jaw separation rate. Carry out the test taking at least five readings at 10 mm intervals from the centre section of each test strip. Aver
36、age the five or more readings for each strip. EN 15386:2007 (E) 8 A.7 Results Peel adhesion (180 ) is expressed as the average result for the strips tested in Newtons per 25 mm width for either 20 min or 24 h application time. A.8 Failure Description Code CP Clear Panel - no visible stain on panel.
37、PS Panel Stain - discoloration of test area, but no tacky residue. CF Cohesive Failure - the adhesive film is split during the test, leaving residue of adhesive on both the panel and the front material. AT Adhesive Transfer - the adhesive separates cleanly from the front material, leaving adhesive f
38、ilm on the test panel. The approximate extent of transfer should be quoted as a percentage. PT Paper Tear - the adhesive force exceeds the strength of a paper facing material. The results quoted should be the maximum reached before the paper tears. EN 15386:2007 (E) 9 Bibliography 1 FINAT Technical
