A number in pa
2、rentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*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 colo
3、rants, stabilizers, or other additives, and can be coated for the improvement of performanceproperties (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 i
4、n SI units are to be regarded as standard. The values given in parentheses are for information only.1.5 The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification: This standarddoes not purport to address all of the safety concerns, if any, associ
5、ated with its use. It is the responsibility of the user of thisstandard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.NOTE 1There is no similar or equivalent ISO known ISO equivalent to this standard.2.

General Requirements4.1 Polymer MaterialThe base polymer shall be a Group 1 or 2 polypropylene (PP), as defined in Specification D4101, or ablend of such Group 1 or 2 PP with one or more other polymers, provided the PP fraction is the main component.4.2 Appear
20、anceThe film shall be as free as commercially feasible of gels, streaks, pinholes, particulate contaminants, andundispersed raw materials. There shall be no other visible defects such as holes, tears, or blisters. The edges shall be free of nicksand cuts visible to the naked eye. There shall be no v

Specific Requirements5.1 The film material shall comply with the definition of oriented PP film (see 3.1).5.2 For the characterization
24、 of commercial PP film, this specification provides a cell classification based on six performanceparameters, as defined in Table 1. Thus, each film is characterized by a code designation consisting of a six-digit number, precededby the acronym OPP-U, OPP-X, or OPP-B.NOTE 2An example of this code de
25、signation would be OPP-B101020, which identifies an untreated balanced film with high gloss and low friction.3 Available from FDA Center for Food Safety and Applied Nutrition, 200 C Street SW, Washington, DC 20204, or on the web at http:/www.access.gpo.gov/nara/cfr/cfr-table-search.html or Telephone
