Collection: MIL-PRF-22191 – Royco Packaging

Transparent barrier materials sound straightforward until the specification requirements come into play. MIL-PRF-22191 governs flexible, heat-sealable packaging films built to meet military waterproofing and low water vapor transmission standards. At Royco Packaging, we stock the full range, with custom conversion available for project-specific sizing needs.

Collection: MIL-PRF-22191

MIL-PRF-22191 covers transparent, flexible, heat-sealable barrier materials with waterproof or low water vapor transmission characteristics for military packaging applications. The current active revision, MIL-PRF-22191F, supersedes the earlier MIL-B-22191 specification.

The specification is divided into three material types, giving procurement teams and packaging engineers options matched to their specific application requirements:

• Type 1: Waterproof, transparent, flexible barrier material for general military packaging use.
• Type 2: Low water vapor transmission material offering a step up in moisture protection.
• Type 3: A higher-performance option combining transparent construction with the most stringent vapor transmission requirements in the specification.

We stock MIL-PRF-22191 material in rolls, pouches, bags, and tubing across a range of standard sizes, with same-day shipment available on in-stock inventory. Projects with non-standard sizing requirements aren't a problem either. Our team converts materials to custom dimensions based on your application's needs.

• Three Material Types Available: Type 1, Type 2, and Type 3 in stock to cover the full range of waterproofing and vapor transmission requirements.
• Multiple Formats In Stock: Rolls, pouches, bags, and tubing available across standard sizes for immediate fulfillment.
