9、 3.2Packaging Material: Shall be sheets or strips of one of the following constructions, heat sealed on the edges, before or during packaging, to form envelopes. Each packaging type is equally acceptable unless a specific type is specified by purchaser. 3.2.1Type I: Both faces of natural kraft paper
10、 of 30 pounds (13.6 kg) minimum weight per ream, lined with polyethylene film not less than 0.0005 inch (0.013 mm) thick. 3.2.2Type II: One face as in 3.2.1 and the other of 300 gage (0.08 mm) cellophane coated with polyethylene film not less than 0.0005 inch (0.013 mm) thick. 3.2.3Type III: Both fa
11、ces U.V. resistant polyethylene film not less than 0.004 inch (0.10 mm) thick. 3.3Preparation: Parts shall be thoroughly cleaned before packaging. 3.4Packaging: Shall be accomplished under conditions which will ensure freedom from contamination by dust, oil, grease, and other extraneous matter. No p
12、art shall be tied or tagged. Parts shall be packaged one to an envelope. Equal size envelopes may be joined to form strips (See Figure 1). Envelopes shall be heat sealed on all edges. Parts larger in OD than can be packaged flat in 18 x 18-inch (457 x 457-mm) envelopes shall be coiled into not more
13、than three coils as shown in Figure 2 or into three loops as shown in Figure 3 for convenience in packaging. When parts are coiled or looped, care shall be exercised to avoid possible cold crease effects. When parts are looped, the looping shall be performed in such a manner that the looped packing
14、cross section is not twisted along its length. If the geometry (cross section and ID) of a part is such that the part is subject to settling to the bottom of the envelope in uncontrolled shape, parts shall be coiled as in Figure 2 or looped as in Figure 3 and packaged in suitable smaller size envelo
15、pes or shall be packaged with sufficient filler packing or cardboard preforms to prevent such uncontrolled settling. Alternatively, unless otherwise specified by part drawing, parts larger than 6.375 inches (161.92 mm) OD may be looped in an odd number of loops as required to suit an envelope size o
16、f 9 inches 0.5 (228.6 mm 12.7) if the envelope is then overpacked as a single unit within a folding paperboard box or corrugated fiberboard folder not less than 1 inch (25.4 mm) thick. 3.4.1Envelope Sizes: the envelope used for each part number should be not larger than necessary to enclose the part
17、 to be packaged without causing deformation or crowding of the part in the envelope. The inside dimension “A” and the width of heat seal dimension “B” (See Figure 1) of envelopes, the maximum ring OD for each envelope size, and the standard size rings to be packed in each without coiling or looping
18、shall be as shown in Table 1.
