This specification covers uniaxially, biaxially, or balanced oriented polypropylene (OPP) films in a specified thickness range. Films can contain colorants, stabilizers, or other additives, and can be coated for the improvement of performance properties such as heat sealability, gas permeability, and so forth. Films can also be annealed (heat-set) to reduce the unrestrained linear shrinkage and shrink tension on exposure to heat. The base polymer shall be a Group 1 or 2 polypropylene (PP), or a blend of such with one or more other polymers, provided the PP fraction is the main component. Films shall adhere to physical requirements as defined for appearance, blocking, thickness, package yield, width, length, and requirements for those intended for the packaging of food, drugs, and cosmetics. For characterization purposes, this specification provides a cell classification based on six performance parameters characterized by a code designation (1 to 6), as follows: (1) coefficient of friction; (2) unrestrained linear thermal shrinkage; (3) wetting tension; (4) heat-sealability; (5) gloss; (6) haze.

1.1 This specification covers oriented polypropylene (OPP) film in the thickness range from 10 to 75 m [0.4 to 3.0 mils].

1.2 The film can contain colorants, stabilizers, or other additives, and can be coated for the improvement of performance properties (heat sealability, gas permeability, and so forth).

1.3 The film can be annealed (heat-set) to reduce the unrestrained linear shrinkage and shrink tension on exposure to heat.

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

1.5 The following safety hazards caveat pertains only to the test methods portion, Section , 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 1—There is no similar or equivalent ISO standard.
