MP Global’s PTAB is a perforated poly wrapped protective, thermal, absorbent, insulating blanket that is designed to be used in conjunction with other thermal protection packaging to enhance and increase the duration of various phase change materials inside a closed thermal container.  PTAB’s are slightly oversized pads designed to fit snuggly to the inner edges of various sized thermal containers.  When pressed to the bottom of the container, they offer payload cushioning, additional thermal duration, and absorption protection in case of unwanted condensation or accidental payload leakage.  An identical PTAB can be placed on the top of the payload area to offer the same protection on the upper portion of the thermal container and eliminate additional unwanted empty space.  Because they are slightly oversized and fit snuggly in the thermal container, no other means are necessary to keep them securely in place.

The insulating material that makes up the inner core of the PTAB pad is made from a proprietary blend of recycled directionally carded fibers which contain an antimicrobial agent, special absorbing fibers, and biodegradable cotton enhanced textile fibers.  These fibers are biodegradable, as tested by ASTM D-6400, and thermally blended to offer the ideal density and variable thickness necessary to attain maximum desired thermal qualities. 
The pad is encapsulated in a perforated proprietary poly film and heat sealed on all four edges. The film also contains a patented additive that promotes biodegradation in a landfill environment in greater than one year.
