By adding a 3D-Watermark to plastics, mostly PET-bottles and trays, FiliGrade provides waste sorting companies a unique method for selecting.
When reading the nearly invisible watermark is exactly known what type of plastic the product is, so an optimal selection can be done. And different to chemical methods: no residu remains so the plastic can be optimal recycled!
Nearly invisible for the human eye, but readable by a (mobile) camera, in infrared, daylight, ultraviolet
The watermark is covering the full product so dirt and distortions have no influence on the readability
FiliGrade patented technology makes a circular economy achievable.
