Mylar® WOL is a biaxially oriented white polyester (PET) film with an amorphous polyester heat seal layer on one side. It is designed to give a peelable seal to a wide range of materials including itself, APET, CPET, PETG, polyester coated board, polycarbonate, and PVC. Mylar® WOL is designed to be self-venting and offers a barrier to visible and UV light.

Mylar® WOL can be used on its own as a single web or as part of a laminate in a wide range of lidding applications, providing reliable sealing and peeling performance. The film is often used for applications where easy opening and opacity are required. For details of sealing conditions and guidance on use, contact your Mylar® Specialty Films technical representative.

Disposal of Mylar® WOL 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.
