Supplies acrylic and styrene acrylic resins to the packaging market for various applications, including lacquering of substrates and metallised webs.

GE Advanced Materials, Quartz is the world's largest producer of boron nitride powders, shapes and coatings, as well as other specialty ceramics. It supplies a full range of ceramic boats to the metallising industry worldwide.
Development of security measures such as RFID, hologram and special printing techniques is ongoing to provide a mechanism that makes it, although not impossible, difficult or too expensive to reproduce as an indistinguishable copy. There is little evidence, however, that metallised paper and board is being utilised in this area. Other techniques, including metallised films and UV- and thermal-sensitive printing, are better suited for this market. Some anti-counterfeiting and tamper-evident papers are being used.
A counterfeit is an imitation that is made with the intent to represent its content or origin deceptively. Counterfeiting is a problem that affects not only money or documents, but also clothing, software, cosmetics, pharmaceuticals, tobacco products, spirits or any other manufactured item. Certain speciality papers for the packaging and/or labelling of the product can be used in the battle against counterfeiting. There are paper substrates that will support holograms, embossing and special metallised finishes, as well as grades that contain a small number of special fibres that make the paper unique.
