MYLAR® CL

Product Description

Mylar® CL is a strong polyester film designed to package foods. Mylar® CL is commercially available in nominal 50 and 100 gauges. The film is typically provided with the sealant side wound toward the core.

General Product Info

This film is similar to Mylar® OL2, however, this film will have much stronger seals at temperatures above 180℉ than OL2. This film withstands freezing temperatures down to -40℉.

Special Features

Corona Treatment (Mylar® CLT): Selected gauges of Mylar® CL are available with corona treatment (on the side opposite the heat seal layer) to enhance printing and laminating. This film type is marketed by Mylar® Specialty Films as Mylar® CLT. 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.

Typical Applications

This film when laminated to foil makes an excellent inner cap seal for PET containers.

Approvals

Disposal

Disposal of Mylar® CL does not present special 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.
