6-6 Magnetic Tapes

Magnetic tapes, cassette tapes, and cartridges present special problems when their mailing containers (especially for small quantities) or reinforcement (for large quantities) are inadequate.

6-6.2 Magnetic Tapes up to 5 Pounds

6-6.2.1 Packing

For a single tape, the tape must be packed in a plastic film wrap of at least 0.75 mil, in a cushioned bag, or in a cushioned paper bag of at least 60-pound basis weight. Multiple tapes up to 5 pounds must be packed in an outer container of fiberboard or chipboard at least 22 mils thick.

6-6.2.2 Closing

The outer mailing container must be securely closed with tape, heat sealing, adhesive, completely clinched staples, or a multiple friction closure (two or more flaps or tabs). Paper tape must be of at least 60-pound basis weight kraft. Shrinkwrap may be used on the outside of an otherwise properly closed box. Reinforced tape is adequate both to close and reinforce the outer container.

6-6.3.1 Packing

A mailing of tapes weighing from 5 to 10 pounds must be packed in an outer container of fiberboard or chipboard at least 22 mils thick. Tapes should be packed in multiple shells for additional protection.
