Material Notes:
Mylar® 850H (also called Mylar® 850) is a co-extruded, one side amorphous, heat sealable polyester film designed to be used in metallized, print, and lamination applications. This film is suitable for use in contact with food.Approvals: FDA Food Contact Status - All gauges of Mylar® 850H (or 850) comply with the Food and Drug Administration regulation 21 CFR 177.1630 -- Polyethylene phthalate polymers. This regulation describes films which may be safely used in contact with all types of food excluding alcoholic beverages. Uncoated films such as Mylar® 850H (or 850) can be used to contain foods during oven cooking or oven baking at temperatures above 250 °F.Information provided by DuPont.
