MylarFoil

As mentioned, a lot of people's first encounter with Mylar is of a version that contains a metalized foil layer adding a reflective sheen to the film. This is a thin Vacuum Metalized layer that adds both a nice metalic look, and increased barrier protection to the Mylar base. This MylarFoil structure has become an industry standard from the afformentioned printed ballooons, to large box liners for industrial shipping. Unlike traditional foil filmstock like what you would see used in old Ketchup packets, the foil layer in MylarFoil is inmcredibly thin - allowing for a more felxible and puncture resistant material with extremely high Oxygen and Moisture barrier properties. The smooth PET top layer is resistant to both oils and solvants (no staining or rust even with MylarFoil), making it a reliable material to use in a wide variety of environments.
