This specification covers the classification of polyethylene film and sheeting. Recycled polyethylene film or resin may be used as feedstock, and the film or sheeting may contain additives for surface property improvement, pigments, or stabilizers, or a combination of these, but they must conform to the requirements specified. Material covered in this specification shall be designated by a five-digit type number, with each numeral (from 0 to 5) indicating the cell limit within which the values of the density, impact strength, kinetic coefficient of friction, haze, and nominal thickness of the material falls under. The sheet or film shall be manufactured free, as commercially possible, of gels, streaks, pinholes, particles of foreign matter, and undispersed raw material, and without any other visible defects such as holes, tears, or blisters. The edges of the sheet or film shall be free of nicks and cuts. The surface of the sheet or film may also be treated by flame, corona discharge, or other means to improve the surface properties. Tests to determine the density, impact strength, kinetic coefficient of friction, haze, and nominal thickness of the material shall be performed and shall conform to the requirements specified.

1.1 This specification covers the classification of polyethylene film and sheeting up to 0.3 mm (0.012 in.) in thickness, inclusive. The film or sheeting may contain additives for the improvement of the surface properties, pigments, or stabilizers, or combinations thereof.

1.2 The values stated in SI units are to be regarded as standard. The values given in brackets are for information only.

1.3 The following precautionary caveat pertains only to the test method portion, Section 8, of this specification: 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.

1.4 This specification allows for the use of recycled polyethylene film or resin as feedstock, in whole or in part, as long as all the requirements as governed by the producer and end user are also met (see Note 1).

Note 1—Guide D7209 describes terminology and definitions related to recycled plastics.

Note 2—There is no known ISO equivalent to this specification.
