Significance and Use
5.1 Elastic recovery is related to the ability of a package to resume its original shape after being distended during its use cycle.
5.2 Elastic recovery also relates to the tightness or snugness of a package.
5.3 Stress retention is related to the tightness or snugness of a package.
1.1 This test method covers the measurement of recovery from extension, permanent deformation, and stress retention of stretch wrap film.
1.2 Several levels of extension are included to ascertain the effect of both small and large extensions.
1.3 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.
1.4 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.
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.
