PPP-B-1672E APPENDIX A
A3.1.1.1.1 Style A. Type I, style A packs shall be sealed with a minimum of 2 inch (48 mm) wide tape conforming to ASTM D5486/D5486M, types I, IV or V applied over all seams, corners, and manufacturer's joints. The tape shall be centered over the seams and joints and shall extend over all the corners and edges of the box a minimum of 2 inches (50 mm) onto the adjacent box panels. Tape shall be applied over the lengthwise seam of the outer flaps, sealing the opening of the box and over the manufacturer's joint prior to tape being applied to the edge seams of the box. The tape applied to the manufacturer's joint shall cover the joint but not extend over the corners of the box onto the adjacent panels. This method also serves as the closure.
A3.1.1.1.2 Styles B and C. Type I, styles B and C packs shall be centrally reinforced with one fully encircling band of 1/2 inch (12 mm) wide tape conforming to ASTM D5330/D5330M, type IV, or 1/4 inch (6 mm) nonmetallic strapping conforming to ASTM D3950 with a minimum tensile strength of 400 lbsf (1790 N). This method serves as the closure. Sealing is not required.
A3.1.1.2 Type II, style D. In the manner specified in A3.1.1.1.1 for style A, seal all open seams and manufacturer's joints with 2 inch (48 mm) wide tape conforming to either ASTM D5486/D5486M, types I, IV or V . This method also serves as the closure.
A3.1.1.3 Type II, style E.
A3.1.1.4 Type III, style G. Type III, style G packs shall be reinforced with fully encircling bands of 1/2 inch (12 mm) wide tape conforming to ASTM D5330/D5330M, type IV or 1/4 inch (6 mm) nonmetallic strapping conforming to ASTM D3950 with a minimum tensile strength of
400 lbsf (1790 N). Two bands shall be positioned 6 inches (155 mm) from the ends over the top, bottom, and sides. Add one lengthwise band over the top, bottom, and ends for XE9 and XF1
Fast Packs. This method serves as the closure. Sealing is not required.
A3.1.1.5. Type IV, Style B. Reinforcement shall be as specified in A3.1.1.3, except the lengthwise band shall not apply. This method serves as the closure. Sealing is not required.
A3.2 Opening of Fast Packs. To open the Fast Pack boxes, the closure and reinforcing tape shall be cut with a shallow knife at a minimum number of seam locations which will permit opening and preclude any damage to the box. Do not remove totally adhered tape.
A3.3 Reuse of Fast Packs. In reusing of Fast Packs, the following procedures should be observed:
a. Surfaces to which tape for closure or reinforcement is to be applied must be free of loose soil, oil, or grease. These surfaces should be wiped clean prior to application of tape.
b. Tape applied to reused containers should be applied directly over the existing tape.
c. Loose ends of existing tape should be cut off, not torn loose. Tearing the tape from the box damages the box surface and weakens the container walls.
