[IMG: Durable Cards using Melinex polyester film]

[H1] Cards

We offer a unique range of biaxially orientated PET films designed specifically for the durable laminated cards market.  The combination of durability, cost effectiveness and simplicity of implementation has made Melinex® polyester film the number one choice in a wide range of National ID applications with over 20% of the world’s population keeping their identity secure with a card based on our products.  Other common applications for Melinex® PET card films are e-Health cards, drivers licences, mass transit ticketing, automotive key cards and many other long life applications worldwide with over 2.5 billion cards issued using Melinex® PET films in the past eight years.
[H2] What is Melinex® PET?
Melinex® is sometimes referred to as BOPET, 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 PVC or PETG. The structure gives it enhanced durability and excellent temperature resistance.

[H2] Melinex® PET –  a more sustainable choice for the cards industry
When it comes to product sustainability, we believe that this should be assessed holistically across the life cycle of our products and taking into account the impact on the wider value chains we operate in.   Across the life time of a card, Melinex® PET films deliver significant sustainability benefits compared to PETG, PV and PC in card laminate structures.
Melinex® has a significantly lower environmental impact during it’s production, with a low carbon foot print, low water usage and with zero hazardous materials used or produced as by products during the manufacturing process.  Melinex® card products are available with high levels of recycled content or 30% bio content further reducing the environmental impact at the start of life.
PET is the most widely recycled plastic globally, and we are actively researching ways of increasing the recycling rates of post industrial and even post consumer waste generated by the cards industry.  As Melinex® PET films are halogen free, they reduce the risk and cost of end of life options such as incineration when compared to other plastic materials often used in cards applications.
However, it is during the course of the product’s life time that Melinex® PET films deliver the biggest sustainability benefit.  Using relatively small percentages of Melinex® PET films in the final laminate structure significantly increases product life time, ultimately leading to the reduction of plastic use by the cards industry.

[H2] Melinex® PET range for cards and typical applications
[H3] Melinex® PET CORE range
The Melinex® CORE polyester film range comprises white films for the card body containing unique toughening agents to offer excellent resistance to flexure and impact.
Not only does Melinex® CORE polyester film offer class leading durability and temperature stability, it can be combined with PVC or PETG using standard lamination equipment without the need for special inks or off-line adhesives.  This flexibility to tailor the amount of Melinex® PET film in the card structure to give the optimum balance between performance and cost effectiveness is one of the key benefits when compared to alternative substrates such as Polycarbonate.
Melinex® CORE1 polyester film has one surface optimised for printing with UV curable and solvent based inks (full bleed printing possible) whilst maintaining good adhesion to overlay grade PVC and PETG.
Melinex® CORE2 polyester film is optimised to be used in conjunction with the Melinex® PROTECT overlay range and UV curable / solvent based inks (requires guilloche printing with > 40% of the card body unprinted). This combination gives the benefit of tamper evidence in the final structure as the two surfaces fuse together and cannot be separated by solvents or temperature.
[H3] Melinex® PET PROTECT range
Melinex® CORE polyester film is complemented by a range of clear, overlay films offering tamper evident credentials and a wide range of personalisation techniques.
SPO – Secure Personalisable Overlay. Suitable for personalisation via direct Dye Diffusion Thermal Transfer (D2T2) printing techniques
SRO – Secure Retransfer Overlay. Outer surface optimised to give excellent adhesion to D2T2 Retransfer printing techniques
LEO – Laser Engravable Overlay. Under development contact us for details.  In the meantime we have a range of structures offering laser engravability in PET composite cards – contact us for details.

[H1] Labels & Digital Print

Melinex® polyester films are the industry standard for durable label facestock films, and are also a preferred substrate for applications such as exhibition graphics, signage, point of sale advertising, and pop up banners.
The dimensional stability and consistency of Melinex® polyester film delivers ease of processing and our range includes a wide range of optical properties including bright white, black, satin matte and ultra-clear films.  Offering the opportunity for sharper graphics and brilliant eye catching images, Melinex® polyester film can be printed on directly using flexographic and UV inkjet technologies or other digital print technologies using a suitable top coating.
[H2] Durability
PET is resistant to a wide range of chemicals making it excellent for highly demanding applications. High levels of thermal and dimensional stability enabling use at elevated temperatures. Building on our experience in the solar industry, the UVHPET™ range offers a viable alternative to PVC in outdoor applications. PET films are widely used in the labels industry, but when it comes to durability not all films offer the same level of performance as Melinex® PET.

[H2] Melinex® PET for Label Facestock Applications
Melinex® films are the industry standard for PET durable facestock and overlamination. Our films are used in applications where durability of the label facestock is critical, such as Automotive, Electronics and Pharmaceuticals. Increasingly Melinex® PET films are being selected as the material of choice in battery and EV applications where the combination of our consistent quality, our 60 years of experience in electrical insulation and our VTM-0 rated flame retardant films give confidence in the most demanding applications. We also offer a range of siliconized release films delivering an ideal balance of performance and cost competitiveness.

[H4] Durability
PET is resistant to a wide range of chemicals making it excellent for highly demanding applications. High levels of thermal and dimensional stability enabling use at elevated temperatures. Building on our experience in the solar industry, the UVHPET™ range offers a viable alternative to PVC in outdoor applications. PET films are widely used in the labels industry, but when it comes to durability not all films offer the same level of performance as Melinex® PET.
In the most demanding applications such as automotive and electronics, Melinex® PET grades have been proven to significantly outperform competitive white PET films in the UL 969 durability test, resulting in significantly less “chalking” after ageing tests.
[H4] Ease of Processing
Excellent stiffness lending itself to reliable high speed labelling processes. Biaxial orientation gives good tensile properties and tear resistance.
[H4] Performance
Electrical properties make PET ideal for the new challenges in batteries and electrical vehicles VTM-0 and VTM-2 options available for the most demanding applications. Excellent printability and appearance of finished label – clear, white, black, matte, gloss options available.
[H4] Sustainability
PET is the most recycled plastic on the planet, and Mylar Specialty Films were the pioneers in the use of recycled content in our film range. Halogen free enabling safe and effective end of life outcomes.
