1. Scope

1.1 This specification covers unpigmented, unsupported, sheet or tubular, medium-density polyethylene films (here-after referred to as film or films) from resins having densities in the range from 926.0 to 938.0 kg/m (0.926 to 0.938 g/cm), inclusive, as measured on molded plaques.

1.2 This specification is applicable to homopolymer polyethylene but is not restricted to it.

1.3 This specification is also applicable to films made from copolymer polyethylene commonly referred to in industry as low-pressure polyethylene.

1.4 This specification is also applicable to films made from blends of homopolymers and copolymers, including ethylene/vinyl-acetate copolymers.

1.5 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 of this specification are met and as long as any specific requirements as governed by the producer and end user are also met (see Note 1).

NOTE 1--Guide D 5033 contains terminology and definitions relating to recycled plastics.

1.6 While much of the content of this specification may also be applied to colored or pigmented films, special care must be exercised. This specification does not address specific problems associated with coloring, such as, quantity and quality of pigment dispersion, optical properties, and increase in density. These and other areas must be taken into account by mutual agreement between the supplier and the purchaser.

1.7 The thickness of the films covered by this specification range from 25 to 100 ┬Ám (0.001 to 0.004 in.), inclusive. The maximum width of the sheet or lay-flat is 3.05 m (120 in.).

1.8 This specification does not cover oriented heat-shrinkable films.

1.9 This specification defines the levels of the various physical properties from which specifications for specific films may be described. The levels of physical properties required by a film for a given application are selected from Section 6 and the corresponding tables. However, Sections 2-5 relating to tolerances shall apply without change to all film falling within the scope indicated by the title and 1.1-1.4.

1.10 This specification covers dimensional tolerances, classification, intrinsic quality requirements, and test methods. The dimensional tolerances include thickness, width, and length or yield. Classification defines types, classes, surfaces, and finishes. The intrinsic quality requirements include density, workmanship, impact strength, tensile strength, heat sealability, and odor, as well as the classification properties for stiffness, coefficient of friction, optical properties, and surface treatment. A sampling method is included.

1.11 The values stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.

1.12 The following precautionary caveat pertains only to the test methods 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.

NOTE 2--There is no similar or equivalent ISO standard.
