MYLAR® OL13 is a biaxially oriented polyester film with an amorphous polyester heat seal layer. It is used as a heat sealable lidding film in packaging refrigerated and frozen foods. OL13 is similar to OL12 but has a thicker seal layer to give enhanced strenght. It can produce a non-peeling "lock-up" type seal and is recommended for hot fill applications where non-peeling seals are desired.
