PERFORMANCE SPECIFICATION: BARRIER MATERIALS, TRANSPARENT, FLEXIBLE, HEAT-SEALABLE (31 MAR 2008) [SUPERSEDING MIL-B-22191D]

BARRIER MATERIALS, TRANSPARENT, FLEXIBLE, HEAT-SEALABLE  

This specification establishes the requirements for transparent, flexible, heatsealable barrier materials having waterproof or low water vapor transmission characteristics for use in military packaging.

Classification. The barrier materials are furnished in the following types and classes.

Type I – Watervaporproof, greaseproof
Class 1 – Unlimited use
Class 2 – For use on automated bag making machines only.

Type II – Waterproof, greaseproof
Class 1 – Unlimited use
Class 2 – For use on automated bag making machines only.

Type III – Waterproof
Class 1 – Unlimited use
Class 2 – For use on automated bag making machines only.

The barrier materials furnished under this specification shall be products that are authorized by the qualifying activity for listing on the applicable qualified products list before contract award.

Material. Barrier materials shall be made from such materials and by such processes as to ensure compliance with the performance requirements of this specification.

Construction. Barrier materials shall be constructed of one or more plies in any manner
which ensures compliance with the performance requirements of this specification. Butting of
component materials or the finished product shall not be permitted except in the direction
perpendicular to the rolling direction. When a butt weld is made on the finished product or any
ply thereof, the areas shall be externally flagged with colored markers to prevent use of that
portion of the roll.

Splices. A roll shall not contain more than 3 splices (4 pieces) and each piece shall be
not less than 45 yards in length. Splices within rolls shall be even the entire width of the roll
material and shall not come apart during unwinding of the roll. Rolls containing splices shall be flagged at both ends of each splice with colored markers to indicate splices within the roll. Barrier material in flat cut sheets shall not contain splices.

Form. The barrier material shall be furnished in rolls or flat cut sheets as specified in
the contract or delivery order.

Rolls. Unless otherwise specified, the width of roll material shall be 36 inches, with a tolerance of plus 1/4 inch or minus 1/8 inch. The average length of roll material shall be not less than 200 yards. The length of any individual roll shall be not less than 195 yards. The roll material shall be uniformly wound on nonreturnable cores. The core’s inside diameter shall be not less than 3 inches, with a tolerance of plus 1/8 inch. The length of the core shall be equal to the width of the roll material, with a tolerance of plus 1/8 inch. The core shall be rigid to prevent distortion of the roll during use and shipment conditions. Each roll shall be restrained to prevent unwinding.

Sheets. When flat cut sheets are specified, the length and width shall be as specified by the acquiring activity. If the length and width tolerances for cut sheets are not specified the tolerance for each shall be plus 1/4.
