ASTM D3354-21
(Test Method)Standard Test Method for Blocking Load of Plastic Film by the Parallel Plate Method
Standard Test Method for Blocking Load of Plastic Film by the Parallel Plate Method
SIGNIFICANCE AND USE
5.1 Blocking develops in film processing and storage when layers of smooth film are in intimate contact with nearly complete exclusion of air. Temperature, or pressure, or both, can induce or change the degree of adhesion of the surfaces.
5.2 The procedure of this test method closely simulates the operation of separating film in some end-use applications.
SCOPE
1.1 This test method yields quantitative information regarding the degree of blocking (unwanted adhesion) existing between layers of plastic film. It is not intended to measure susceptibility to blocking.
1.2 By this procedure, the film-to-film adhesion, expressed as a blocking load in grams, will cause two layers of film with an area of contact of 100 cm2 to separate. The test method is limited to a maximum load of 200 g.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: This test method is similar to ISO 11502 Method B, but is not technically equivalent.
1.5 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.

4.1 Two pieces of film, which are in contact with each other, are placed between two 100-mm (4-in.) square blocks. The ends of
the films that extend past the blocks are secured to the respective upper and lower block. The force required to overcome the
adhesion (blocking force) between the two pieces of film or until they reach 1.9 cm of separation is measured in grams using a
constant-rate-of-load or a constant-rate-of separation device.
