MIL-PRF-131L MIL-SPEC Bags, Pouches & Packaging

If you’re in the business of manufacturing, distributing or shipping products intended for military or federal applications, you’re required to adhere to stringent packaging requirements. Fortunately, at Caltex Plastics, we have more than three decades of experience manufacturing packaging materials and products for military use.

Items and components intended for use in a naval or naval aviation environment must be able to withstand harsh surroundings that contain high levels of moisture and salt. That’s why we offer a line of water-vapor-proof packaging materials that provide robust barrier protection for items that are susceptible to corrosion. In fact, we manufacture our own MIL-PRF-131L (formerly known as MIL-B-131K, MIL-PRF-131K and MIL-PRF-131J QPL material (CALPAC ULTRAFOIL 500M and 1000M) to ensure our customers are getting the absolute best protection.

HEAT-SEALABLE MIL-SPEC-PRF-131L BAGS

The following packaging products are both vapor-proof and heat-sealable:

• MIL-PRF-131L Class 1 ULTRAFOIL 500M: This sturdy foil-based moisture barrier laminate has a low-density polyethylene inner layer and can be used for a wide range of applications. It’s lightweight, flexible, heat-sealable, waterproof and greaseproof — plus, it’s resistant to many chemicals, including non-volatile residues and the effects of outgassing. Available in bottom, side and zipper configurations, it’s extremely tear- and puncture-resistant as well. It can be used for vacuum packaging — including applications that require nitrogen flushing — and conforms easily to the shape of items.
• MIL-PRF-131L Class 1 ULTRAFOIL 1000M: This super heavy-duty packaging is a foil-based moisture barrier laminate. It’s specifically designed to resist tearing and punctures, as well as to minimize contamination resulting from chemicals, including from sources such as non-volatile residues and outgassing. It’s lightweight and suitable for vacuum packaging, including applications that involve nitrogen flushing. Bottom, side and zipper configurations are all available.
• MIL-SPEC-PRF-131L Class 2 Packaging: These vapor-proof paper MIL-SPEC-PRF bags are manufactured using a layered structure of paper / polyethylene / foil / polyethylene and are converted in compliance with MIL-DTL-117. They’re heat-sealable, flexible and perfect for applications that require a moisture barrier.
• MIL-SPEC-PRF-131L Class 3 Packaging

MIL-SPEC COMPLIANCE

Every day, the men and women in our armed forces are willing to put their lives on the line for our country. As such, it’s the duty of organizations that supply products to the military or transport goods for military use to ensure that the items in question are protected from damage and contamination.

To make sure, the Department of Defense — or DoD — has issued a set of specifications that govern both the items and the packaging used to transport them. Consequently, organizations working with the military are required to comply with these regulations. Since 2001, MIL-SPEC-DTL 117 are the regulations that cover which types of shipping and packaging materials may be used.
