C-3. Substitution List for Cushioning Materials

Semirigid FIP (0.5 density) is acceptable for limited cushioning, and rigid foam (2.0 density) is acceptable for blocking

and bracing materials. Substitute materials that can be used when foam is not available are listed in table C-3. When

selecting a substitute for interior cushioning (against a bare item), three requirements must be met. The cushioning must

be as dry as practical; it must be noncorrosive; and, if the item is coated with a preservative, it must first be wrapped with

a greaseproof barrier material.

Specified tapes used in container closure are listed in column one of table C-4. Column five contains a list of substitute

tapes that can be used when the required tapes are not available. If substitute tapes cannot be obtained, MMM-A-250,

C-5. Label Adhesive and Transparent Tape (for Applying Printed Labels to a Container)

MIL-STD-129 authorizes the use of printed, paper labels for marking interior packages, shipping containers, and loose or

unpacked items. When using these labels, securely affix them with water-resistant label adhesive or transparent tape.

Table C-5 lists substitute materials that can be used when specified materials are not available.
