As a result of interest shown by the aerospace electro-optics community, Drytech has developed a highly robust miniature bag to protect laser and optical cavities of different systems. Typically, small heat fused MIL-D-3464 type sachets have tensile seam strength of less than 3 lbs. per inch of seam.

Drytech has introduced a technology, which seals the Tyvek® bags with a much improved tensile seam strength in excess of 7 lbs. per inch of seam average, producing a highly reliable and robust bag when exposed to high vibration and shock environments. Test procedure as depicted in Diagram (a).

Additionally Drytech offers an Armored bag fabricated from stainless steel wire cloth. Typically these Armored units are used in high temperature and harsh environments where Tyvek® will fail.
