Black Plastic Packaging
Colloids has developed two innovative new NIR-detectable black masterbatch products which can be used for a wide range of packaging.
According to WRAP, around 30,000-60,000 tonnes of black plastic packaging enters the UK household waste stream each year, much of which is undetectable by the machinery used in recycling plants. The amount of black plastic use continues to grow, with no clear recycling option available.
Detection is the Key
The carbon black-based masterbatches and compounds used in black products make the base polymer undetectable by recycling facilities using near-infrared (NIR) spectroscopy technology. This means much of the commonly used PE, PP and PET black plastics from mixed-plastic household waste that could be recycled is missed and ends up in landfill.
Technical Solution
To help solve this chronic waste issue, Colloids has developed two innovative new NIR-detectable black masterbatch products which can be used for a wide range of packaging in addition to food trays, such as containers, caps, sheet and film products:
MPT9D2281 NIR grade for black PET food trays
MPE9D2282 grade for black PP or PE trays
These NIR black masterbatch grade options are formulated for production using conventional lines and processes for plastics including: injection moulding, blow moulding, blown and cast film, rod, plate, tube and thin sheet extrusion.
Colloids offers producers bespoke solutions, with black NIR detectable masterbatches or compounds made to order, for all commonly used polymers for flexible and rigid black plastic packaging, including: APET, CPET, PBT, PP, HDPE, LDPE, LLDPE, PS, ABS, PC, PCABS and EVA. Both formulations meet EC AP (89)1 European Resolution on the use of colourants in plastic materials coming into contact with food.
