General Product Info: This film is similar to Mylar® OL2, however, this film will have much stronger seals at temperatures above 180°F than OL2. This film withstands freezing temperatures down to -40°F. Mylar® CL softens in the range of 425°-450°F.
Typical Applications: This film when laminated to foil makes an excellent inner cap seal for PET jars. This film is also suitable for heating food products in microwave or conventional ovens.
Approvals: FDA Food Contact Status - All gauges of Mylar® CL 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® CL can be used to contain foods during oven cooking or oven baking at temperatures above 250 °F.
