Black Plastic Bans Are Spreading. What Carbon Black Means for Black Bottles
By Joe Joo · 8PCK · Shantou
Plastics News reports bans on black plastic takeout containers. The problem is not the colour — it is carbon black pigment, which sorting equipment cannot see. Black cosmetic bottles face the same issue.
What Changed
Plastics News reports that bans on black plastic takeout containers are spreading across US jurisdictions. The stated reason is rarely aesthetic: near-infrared sorting equipment cannot detect carbon black, so a black container falls through the recycling line and ends up in residue.
What It Means for Buyers
That matters well beyond takeout. Black is one of the most common cosmetic bottle colours, and it is usually produced with carbon black masterbatch. A black shampoo bottle has the same sorting problem as a black food container — the pack is invisible to the optical sorter.
There are three practical routes. First, keep black and accept that the pack will not be sorted; make no recyclability claim. Second, switch to a dark colour that is detectable — deep green, brown or navy read as “black” on shelf and are visible to NIR. Third, use a detectable black masterbatch, which exists but adds cost and needs to be confirmed with the recycler rather than the pigment supplier.
What to Ask a Supplier
For a buyer, the question to put to a supplier is specific: is the masterbatch carbon-black based, and if so, is the pack intended for a stream that sorts it. If the answer is “it is just black”, the pack is not recyclable in most curbside systems — and a recyclability claim on the artwork will not survive a retailer audit.
We mould black bottles in PET and HDPE. When a brand needs a recyclability story, we quote deep green or a detectable black instead, and say which one we are shipping.
What It Changes in a Bottle Spec
The Pigment Is the Problem, Not the Colour
Near-infrared sorting cannot see carbon black. A black shampoo bottle has the same sorting problem as a black food container.
Three Routes for a Black Pack
Keep black and make no recyclability claim; switch to a deep green or brown that reads black and is detectable; or use a detectable black masterbatch, confirmed with the recycler rather than the pigment supplier.
