DYMAT® PYE MONO

Best selling and Single layer

This new generation of backsheet from Coveme is based on a single PET layer (Mono Layer) that features superior resistance to UV and hydrolysis thanks to its bulk technology. Contrarily to the co-extrusion technology, the bulk technology features the UV protection all across the whole thickness of the single PET layer. Coveme’s monolayer backsheet shows excellent performances in the combined UV+DHT tests as well as it features an intrinsic high reflectivity.
The range also includes a version of the revolutionary dyMat® ECO range composed of 33% recycled polyester (rPET) coming from post-consumer waste recycling. dyMat® ECO PYE r33 MONO L PLUS is the very first backsheet made with rPET availabe on the market today.
