Significance and Use
This guide is for user evaluation, selection, specification, and application of stretch wrap materials. It may be used between the buyer and seller to arrive at purchase specifications. Specific methods are contained within the body of the guide for material evaluation, user performance, and quality assurance testing.
Care must be exercised in extrapolating test values obtained by use of the test methods outlined in this guide, to actual field performance.
1.1 This guide covers recommended guidelines and test methods for the selection, specification, and use of stretch wrap films for unitizing, reinforcing, and palletizing for indoor environments. This can include storage or transport, or both, in warehouses, closed containers such as truck trailers or rail boxcars, and associated transfer terminals. This guide does not cover the performance issues associated with outdoor exposure.
1.2 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.
1.3 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.
A1.1.1 This test method is intended to be used as a means of comparing the wrapping performance of stretch wrap films.
