Technical Data Sheet: Mylar® 850 Polyester Film
Please note that laminated film (such as in our multi-layer Mylar® bags which have PET/Foil/Poly/Nylon and other layers such as those found on www.discountmylarbags.com) will have even better OVTR, MVTR and other physical characteristics. These values are for only the Mylar® layer. Our aluminum foil layer provides even better protection and provides the bulk of protection in a Mylar bag.
