AUTHORIZED SUBSTITUTES FOR PACKAGING MATERIALS

C-1. Substitution List for P-type Preservatives

When determining the proper preservative to be used as a substitute when the originally specified material is not

available, certain factors should be considered. They area.

a. Characteristics of the item. These include composition, surface finish, complexity of construction, size, and

shape.

b. Characteristics of the preservative. These include chemical composition, chemical consistency (thickness or

thinness), hard drying (or not), and method of application (hot or cold).

c. Extent of protection desired. If the item is to be used within a relatively short period of time, only a light,

temporary preservative is required. However, if the item is to be stored for a long period of time, then a longer lasting

protective coating is required.

d. Ease of removal. Whether or not someone in the field is able, with normal resources, to remove the

preservative with little difficulty. Preservative substitutes listed in table C-1 shall be used only when the specified

material is not available.

*Substitute is not available.

Note: If a suitable substitute is not available, consider upgrading the method of preservation. For example, use method

IC instead of method I, method IA instead of method IC, or method II instead of method IA. However, method

substitution does not replace the preservative requirement.

C-2. Substitution List for Barrier Materials (Including Bags and Wraps)

Materials in column one of table C-2 are commonly referred to as "barrier materials" throughout this manual. The

prescribed substitutes, listed in column two, also apply when the packaging reference specifies the use of bags, sleeves,

or tubing as interior wraps. When fabricating bags, refer to MIL-B-117 for information on the type, grade, and class and

on the weight and size limitations.
