CALPAC ULTRAFOIL 500M


Description

CALPAC ULTRAFOIL 500M is a heavy duty, foil-based, moisture barrier laminate designed for a wide variety of applications. It is designed to minimize contamination from sources including outgassing and non volatile residues in addition to being waterproof, greaseproof, flexible and heat sealable. With excellent puncture and tear resistance, it is well suited for packaging items large or small that require protection from the elements.

This moisture barrier film is on the QPL for MIL-PRF-131K and is converted in accordance with MIL-DTL-117H.



(Excerpt from the MIL-PRF-131K specification.)

MIL-PRF-131K Class 1 (general use). Class 1 material with plastic non-woven backing is intended to be used in all packaging applications where heat-sealable, flexible, watervaporproof, greaseproof, barrier materials are required.

Intended use – The barrier materials covered by this specification are intended for use in specialized military methods of preservation. The combination of all performance characteristics of MIL-PRF-131; seam strength and fabrication; water vapor transmission rate; breaking strength; puncture, blocking and curl resistance; contact corrosivity; delamination; and water resistance of markings provide the necessary requirements for protection from exposure to the extremes of the navy/naval aviation environment. Navy/naval aviation items are exposed to high moisture, high salt concentration, transfer at sea, rough handling, and minimal storage conditions. There are no commercial equivalents that meet the physical, mechanical, and corrosion requirements necessary to protect materiel that is exposed to the operational naval aviation environment. Specifically, Methods 41, 42, 43, 51, 52, and 53 of MIL-STD-2073-1 use MIL-PRF-131 as the premier source of barrier materials that provide watervaporproof (and watervaporproof with desiccant) protection for applicable items encountering the above conditions.
