Highlight on our Lumirror® matt films
Toray has long been developing films with unique technical properties for diverse specialty markets. It is the case of our Lumirror® matt film range that have been developed for a wide range of applications such as release liners, carrier films, sublimation inks transfer and roughness transfer.
Technicity of Toray’s Lumirror® matt films
Common properties of our Lumirror® matt films:
• Thickness from 20 to 125 µm
• Low gloss range
• Permanent matt aspect
• Controled roughness for surface transfer
• High roughness for improved winding quality
• Low shrinkage to ensure good dimensional stability during manufacturing process
• Repeatable quality with high process capability
The Lumirror® range of brand new smooth/matt & 2-side matt films are suitable as release liners or processing films:
• The rough side offers a great and efficient winding quality.
• The Lumirror® pretreated films are fit for printing and adhesion promotion (Inks, adhesives…)
Smooth/matt film: This dual surface film has both smooth and matt sides. It is a high roughness polyester film that has been designed to gain a process step on casting & coating processes. On one side, its rough surface enables excellent winding quality. On the other side, the smooth surface allows it to be used for coating of silicone or casting of PU or PVC for instance.
Pretreated matt films: In addition of having the same benefits of the 2-side matt or smooth/matt, those films also have a printable coating on one side.
Different applications of Toray’s Lumirror® matt films
The various properties of Lumirror® matt films allow different uses.
Following are some examples of applications:
• Release liner
• Textile transfer
• Replacement of paper sheet
• Roughness transfer in casting applications
Advantages of PET in opposition to paper
Our Lumirror® matt films range is a great alternative to paper. In fact, the use of PET will allow a drastic reduction of dust creation during slitting. Furthermore, PET thermal resistance is higher and the film is not hydrophilic as which could be the case for some papers.
