    1、Designation: D 2673 09Standard Specification forOriented Polypropylene Film1This standard is issued under the fixed designation D 2673; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthe

    2、ses 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 colorants,

    3、stabilizers, or otheradditives, and can be coated for the improvement of perfor-mance properties (heat sealability, gas permeability, and soforth).1.3 The film can be annealed (heat-set) to reduce theunrestrained linear shrinkage and shrink tension on exposure toheat.1.4 The values stated in SI unit

    4、s are to be regarded asstandard. The values given in parentheses are for informationonly.1.5 The following safety hazards caveat pertains only to thetest methods portion, Section 7, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its

    5、 use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.NOTE 1There is no similar or equivalent ISO standard.2.

General Requirements4.1 Polymer MaterialThe base polymer shall be a Group1 or 2 polypropylene (PP), as defined in Specification D 4101,or a blend of such Group 1 or 2 PP with one or more otherpolymers, provided the PP fraction is the main component.4.2 A

    18、ppearanceThe film shall be as free as commerciallyfeasible of gels, streaks, pinholes, particulate contaminants,and undispersed raw materials. There shall be no other visibledefects such as holes, tears, or blisters. The edges shall be freeof nicks and cuts visible to the naked eye. There shall be n

    21、 RequirementsFilms intended for thepackaging of food, drugs, and cosmetics shall comply with therequirements of the Federal Food, Drug, and Cosmetic Act asamended.35. Specific Requirements5.1 The film material shall comply with the definition oforiented PP film (see 3.1).5.2 For the characterization

    22、 of commercial PP film, thisspecification provides a cell classification based on six perfor-mance parameters, as defined in Table 1. Thus, each film ischaracterized by a code designation consisting of a six-digitnumber, preceded by the acronym OPP-U, OPP-X, or OPP-B.NOTE 2An example of this code de

    23、signation would be OPP-B101020,which identifies an untreated balanced film with high gloss and lowfriction.6. Sampling6.1 Adequate statistical sampling shall be considered anacceptable alternative.Abatch or lot of film shall be consideredas a unit of manufacture as prepared for shipment.7. Test Meth

In cases of disagreement, thetolerance shall be 61C (61.8F).7.2 Test ConditionsConduct the test

    25、s at 23 6 2C (73.4 63.6F) unless otherwise specified in the test methods or in thisspecification. In cases of disagreement, the tolerance shall be61C (61.8F).7.3 In addition, for films containing hydrophilic fillers,co-monomers, pigments or other modifiers, conditioning andtesting shall be done at 5
