MYLAR® OL12

Product Description

Mylar® OL12 is a biaxially oriented polyester (OPET) film with an amorphous polyester heat seal layer. It is used as a heat sealable lidding film in packaging refrigerated and frozen foods. Mylar® OL12 is commercially available in nominal 100 and 150 gauges.

Mylar® OL12 provides strong, aggressive seals to polar substrates such as amorphous polyester (APET, also PETG), semicrystalline polyester (CPET), polyester coated paperboard, polyvinylchloride (PVC), and aluminum. Mylar® OL12 does not seal to polyethylene, polypropylene, or polystyrene. Mylar® Specialty Films offers another family of lidding films (RL types) for sealing to these substrates. Mylar® OL12 can withstand freezing temperatures down to -40℉.

Mylar® OL12 has higher hot tack and a thicker seal layer than either Mylar® OL or OL2, and can be used in hot fill applications. It is not recommended for applications requiring retort sterilization. Mylar® OL12 lidding films have excellent grease and oil resistance. Heat seals produced with Mylar® OL12 are stronger than with Mylar® OL2 (or OL) and may be difficult to peel without shredding.

Special Features

Corona Treatment (Mylar® OL12): Selected gauges of Mylar® OL12 are available with corona treatment (opposite the heat seal layer) to enhance printing and laminating. This film type is marketed by Mylar® Specialty Films as Mylar® OL12T. The film is treated to an initial dyne level of 54. The dyne level of treated lidding films may decline with storage, and in-line corona treatment may be required during subsequent printing or laminating to increase the dyne level to a value adequate to get desired ink or laminate adhesion. Standard put-ups for Mylar® OL12T are the same as shown for Mylar® OL12.

Anti-fog (Mylar® OL12AF, OL12AT): Selected gauges of Mylar® OL12 lidding films are available with anti-fogging capability to provide better clarity when stored and displayed in refrigerated conditions. This film type is marketed by Mylar® Specialty Films as Mylar® OL12AF. Mylar® OL12AF is also available with corona treatment on opposite side of film from the heat seal layer. This film type is marketed by Mylar® Specialty Films as Mylar® OL12AT. Standard put-ups for Mylar® OL12AF and OL12AT are the same as shown for Mylar® OL12.

Disposal

Disposal of Mylar® OL12 does not present special disposal problems. It can be buried as a relatively inert material in a landfill or burned in an incinerator with normal refuse. The incinerator should have sufficient draft to exhaust all combustion products through the stack to avoid exposure to irritating fumes. The disposal method should comply with local, state and federal regulations.
