Significance and Use | ||||||||||||
Test Method F88 has been the standard for the mechanical peel strength testing of peelable seals since the 1960s. Normally the testing is run on a portion of the seal. The result is an actual seal strength picture of that portion of the seal. This test method is different in that the entire package seal is peeled open and data collected for the entire sealed area. This test method is a tool for quality assurance use as well as performance evaluation of a seal during separation. With appropriate software, data is collected depicting the seal strength of the entire length of the seal. As a result, it is possible to see seal strength variations, as the seal is peeled apart, thereby evaluating the consistency and uniformity of the seal (see Fig. 1). |

1. Scope | ||||||||||||
1.1 This test method describes a method for the measurement of mechanical seal strength while separating the entire lid (cover/membrane) from a rigid or semi-rigid round container. 1.2 This test method differs from Test Method F88. Test Method F88 tests a portion of the seal where as this test method tests the force required to separate the entire lid (cover/membrane) from the container. 1.3 This test method is used to determine the continuous and maximum forces required to separate the lid (cover/membrane) from the container. 1.4 This test method uses an angle of pull of 45°, however other angles of pull may be used provided results are documented noting the used angle of pull and said procedure is validated. 1.5 Typical examples of container shapes that could be tested using this or a similar method include oval, rectangular, and circular with single or multiple cavities having a sealed lid (cover/membrane). Examples of products packaged in these types of containers are: ready meals, creamers, coffee, yogurts, household fresheners, chemical and pharmaceutical products, and numerous others not mentioned. However, this test method, described within, is specifically for round containers. 1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use. |
