MIL-DTL-17667 Chemically Neutral Wrapping Paper – Royco Packaging

MIL-DTL-17667 is a military specification for chemically neutral, corrosion-inhibitor-free wrapping paper used around metals and precision components. The paper is designed to avoid the chemical reactions that can occur when sensitive surfaces are wrapped in acidic or otherwise incompatible paper. Royco Packaging supplies MIL-DTL-17667E Type I and Type II papers for storage, shipment, interleaving, and use inside larger barrier packaging systems. They can be used as an inner wrap with MIL-PRF-131 barrier materials or alongside desiccants and VCI products when additional environmental protection is required. Royco also offers custom sizing for projects that need dimensions outside standard roll or sheet formats.

MIL-DTL-17667 Type I and Type II differ mainly in physical form. Type I is a flat, smooth paper intended for general wrapping and interleaving where even surface contact is desirable. Type II is creped, making it more stretchable and conformable around irregular components, edges, and complex shapes. Both types are chemically neutral and corrosion-inhibitor-free, and Royco Packaging states that they undergo testing for neutrality, non-corrosiveness, and tensile strength. The correct type depends on the part geometry and how the paper will be used in the preservation system. Royco can supply both types and custom-cut material when standard dimensions are not suitable for the application.

Yes. MIL-DTL-17667 paper is specifically intended to be chemically neutral and non-corrosive, making it appropriate for protecting sensitive metals, finishes, and alloys when used according to the specification. That is why it is often selected as an inner wrap or interleaving material around precision parts before they are placed in a barrier pouch or other preservation package. Royco Packaging supplies both Type I flat paper and Type II creped paper and states that the materials are batch tested for neutrality, non-corrosiveness, and tensile performance. Customers should still consider any highly specialized coating, surface treatment, or compatibility requirement for the specific part and contract.

Yes. Royco Packaging can provide MIL-DTL-17667 wrapping paper in custom dimensions for projects where standard roll or sheet sizes do not fit the part or packaging process. Custom cutting is useful for interleaving precision components, wrapping irregular equipment, creating repeatable work instructions, or reducing waste on a production line. Royco’s team can help select Type I flat paper or Type II creped paper and then size the material to the application. For military packaging programs, customers should provide the exact specification revision, desired dimensions, quantity, and any documentation requirements. Royco can also coordinate MIL-DTL-17667 paper with barrier films, desiccants, and VCI materials used in the same preservation system.

MIL-DTL-17667E supersedes the older MIL-P-17667D specification. Customers may still encounter the legacy designation on older drawings, technical data packages, or procurement documents, so it is important to recognize that the newer MIL-DTL designation is the current specification. Royco Packaging supplies chemically neutral wrapping paper under MIL-DTL-17667 and can help customers interpret legacy references when sourcing replacement material. The specification includes Type I flat paper and Type II creped paper, both intended to protect metals and precision components without introducing corrosive chemistry. If a contract explicitly requires an older revision, Royco’s packaging specialists can help determine the correct current product and documentation path.
