What is a mil? A mil is a unit of measurement used to determine thickness. 1mil is equal to .001 (1/1000) inch. All of Dr. Shrink's material is made with 100% virgin resin, guaranteeing true mil thickness and consistency on each roll of shrinkwrap.
6mil—is our thinnest shrinkwrap
and is used on smaller items such as boats, shed frames, pallets and
machinery that will be stored rather than transported.
7mil—is
the standard thickness for shrinkwrapping boats in snow load areas, for
light construction jobs and for medium sized machinery that will be
transported.
8mil/8.5mil—is an excellent thickness for covering
large boats, shrinkwrapping large building frames, and for wrapping
large equipment with sharp protrusions for transportation or storage.
