Recyclable, metallised coatings for PET bottles

Singulus Technologies, a global provider of production technologies for the manufacturing of high-tech products, introduces metallised coatings that are claimed to be recyclable.

Traditional metallised coatings often utilise non-recyclable materials and harmful substances, raising environmental concerns. Addressing this issue, Singulus Technologies has successfully produced metallised finishes on PET plastic that have passed key recyclability tests, including metal detection and NIR resin identification. These tests were conducted by certified test facilities of the Association of Plastic Recyclers (APR).

Compared to conventional metallising processes, Singulus Technologies says that the new coatings offer advantages such as:

  • Resin-based spray primers and topcoats can be avoided on various substrates, including PET, SAN, and glass.
  • Applying the coatings requires less energy, resulting in over 70% reduction and cost savings.
  • The processes emit zero VOCs, eliminating the need for EPA reporting.
