When manufacturing products for the military, adherence to strict guidelines and standards is paramount. Among these packaging standards is MIL PRF-131, a crucial specification delineating the requirements for packaging solutions utilized in military equipment.
What is MIL PRF-131?
MIL PRF-131L is a military specification formulated by the United States Department of Defense, outlining the requirements for packaging solutions employed in military equipment. Its purpose is to ensure that military equipment meets strict performance and quality standards.
Formally referred to as Mil-PRF-131K, in April of 2022, the specification was changed to Mil-PRF-131K. The main reason for revising the spec was the elimination of Class 2. The class 2 specification materials were listed as Kraft paper, laminated to foil and plastic.
Importance of MIL PRF-131 for Manufacturers
Manufacturers find MIL PRF-131 indispensable because it shields products from moisture-vapor and oxygen on military equipment and exhibits high quality and resilience in the face of harsh climatic conditions.
Mil-PRF-131 Packaging Types By Class
There are separate classes of Mil-PRF-131 material, each class offers different properties.
Class 1
This material is intended for general use in packaging applications that require flexible, heat-sealable, water vapor proof, greaseproof, and barrier materials. It’s the most common MIL-SPEC packaging material designed for moisture-sensitive government products, usually military items.
Class 2
This material is no longer officially listed but is still available for purchase.
Class 3
This material is similar to Class 1 but is used for applications that require a higher strength heat-sealable, flexible, water vapor proof, greaseproof barrier material.
Requirements of MIL PRF-131
Mil-PRF-131 Class 1 materials must include the following printed in a lusterless red:
- Material Code
- Manufacturer
- Batch Number
- Lot Number
- Nomenclature
- Moisture Transmission Rate
- Sealing Guidelines
These specifications allow the protective barrier material to offer the highest standards of protection, as well as traceability.
Benefits of Using MIL PRF-131 Class 1 Packaging
Using MIL PRF-131L Class 1 materials provides several advantages for manufacturers:
Meeting Military Requirements
