Why choose Melinex® PETF?
Melinex® Polyester Film has a long history of providing custom designed films for use in the cards market. With outstanding thermal properties and controlled profile consistency, Melinex® films are the ultimate material for a multitude of card applications.
What is Melinex® PETF?
- PVC, PETG and PC are all amorphous polymer materials which means their structure is made up of polymer chains which have no specific structure
- Melinex® is sometimes referred to as PET or PETF. It is a biaxially oriented crystalline material with polymer chains locked together in a specific lattice structure. This means it is a much higher performing material than PETG. The structure gives it enhanced durability and excellent temperature resistance

Technical Benefits of Cards made with Melinex®
- Flex Resistance
- ISO Flex Test uses repeated flexions of card to simulate day to day use
- Appearance of card monitored through cycles to check for cracks and card failures
- PETF showed no failures at the end of the test, other cards failed in the region of implant module
- Solvent Resistance
- Melinex® has excellent resistance to embrittlement and premature failure caused by plasticisers found in wallets
- Test method involves adding a small droplet of DOP to the card surface and placing it in a static stress fixture
- Test measures hours before card fracture occurs (Test methods: INCITS322 & ISO24789-2)
- Temperature ResistanceTemperature Resistance
- Melinex® PETF provides excellent performance at elevated temperatures due to the crystallisation process(230ºC for extended period)during manufacturing
- Melinex® PETF offers superior thermal stability compared to both PETG and PVC
- PETF is used extensively in flexible electronics applications (continuous use -70ºC – 130ºC)
Melinex® and the Environment
- PETF is the most widely recycled polymer in the world
- PETF substrates can be produced with post consumer polymer made recycled bottles
- PETF can be produced from raw materials derived from plant materials
- The manufacture of PETF does not include the use of controversial chemicals such as BisPhenol A
- PETF is widely used in food packaging applications
