Historical (view previous versions of standard)
This specification covers annealed aluminum and aluminum-alloy foil used in packaging, which includes food handling and processing applications, requiring flexible barrier materials, and other general applications. The foil may also be as supplied or laminated to other materials, such as paper or plastic films. Chemical composition shall be in conformity with provisions herein, and shall be determined through suitable chemical and spectrochemical methods. Tensile breaking load limits shall be as agreed, and shall be tested twice with test methods for tension testing of metallic foil using two samples from different rolls of foil.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers annealed aluminum and aluminum-alloy foil containing 98.00 % minimum aluminum and in thicknesses 0.00025 in. (0.0064 mm) to, but not including, 0.006 in. (0.15 mm). Alloys (see Note 0) covered by this specification include, but are not limited to 1100, 1145, 1235, 8011, 8079, and 8111, which conform to the requirements of and . Unless otherwise specified by the purchaser, the alloy to be supplied shall be left to the discretion of the producer.
1.2 The foil is for use in packaging, which includes food handling and processing applications, requiring flexible barrier materials, and other general applications. The foil may be used as supplied or laminated to other materials, such as paper or plastic films.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see .
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI values in parentheses are for information only.
Throughout this specification, use of the term alloyin the general sense includes aluminum as well as aluminum alloy.Note 2
If the alloy is specified by the purchaser, its designation shall be in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those shown in preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527.
