Black plastic: listed or blacklisted?

(Excerpt from Plastics in Packaging November 2019 Issue) The colour black in food and other types of consumer packaging has become a hotly-contested topic, given the challenges with carbon black in identifying the base polymer for recycling. Paul Gander looks at some of the alternative strategies.

While the majority of plastics packaging might be said to have a ‘visibility’ problem, which counts against it in the eyes of many consumers and much of the media, with black plastics this is more of an ‘invisibility’ problem.

Whether the packaging is black or a dark containing the same colourant, the challenge is that carbon black can render the item undetectable by near-infrared (NIR) identification systems, typically used in materials recovery facilities (MRFs) around the world. As a result, this stream has frequently been inaccurately described as ‘unrecyclable’.

In the UK especially, this is one plastics-related issue that predates the BBC Blue Planet 2 marine wildlife series, as business development manager at Faerch Plast UK Ruth Price explains. “Even before then, there was a lot of media attention given to the way black plastics were not being recycled,” she says. “That in turn was putting pressure on the use of black trays, even though they are recyclable.”

Are black plastics just a UK problem? At The Shepherd Color Company in the US, marketing manager Mark Ryan says it is now on its fifth generation of IR blacks, developed over some 40 years. But applications to date have principally been in vinyl for outdoor use requiring solar reflectivity. Those same properties make the additives ideal for IR reflectivity.

Following Europe’s lead, the issue of black plastics packaging and recycling is starting to come to the fore in the US, says Ryan. He highlights the boom in food delivery services in the US where, he says, providers will often use black plastics for their meals.

More broadly, he says: “Recycling rates in the US are so much lower, generally, than in Europe. Any initiative that helps has to be good.”

Formulating the ‘Black Rainbow’

Who Says a Rainbow Has to Be Colorful?

For 40 years, The Shepherd Color Company has been producing a wide range of high-performance color pigments, many of which are infrared reflecting (IR) Black pigments. Our Black pigments for coatings and plastics all vary in masstone jetness, Total Solar Reflectance (TSR), and tint strength, the three main properties of an IR Black pigment. This forms the foundation of the ‘Black Rainbow’. Find what products make up the Shepherd Color ‘Black Rainbow’ here.

PRESS RELEASE: Shepherd Color Announces New IR Black for Recycling of Black Plastic

(CINCINNATI, OH, June 17, 2020) It seems that the Shepherd Color’s R&D team is at it again. ‘Creating Value, Brightening Lives’ has long been the Core Value of The Shepherd Color Company. The R&D Team has their pulse on the coatings and plastics industries to understand the needs of their customers: to create quality, innovative products, which bring value to not only their customers, but to the sustainability of the environment.

One such product is a cost-effective IR Black colorant for packaging that can reflect IR wavelengths in recycling sorting facilities, so these plastics may be recycled. Black is a popular color used for plastic packaging, which is mostly carbon black pigment. The carbon black pigmentation absorbs the light from the emitter used in plastic sorting centers, which prevents the sensor from identifying the polymer used, so the material is then rejected and not recycled (see illustration below).

Shepherd Color has spent the last 40 years developing, optimizing, and manufacturing IR Black pigments. Based on the new balance of properties needed for the recycling application, they were able to design, prototype and scale up an IR Black pigment to meet this new need. This IR Black pigment advancement is Arctic® Black 10P925. The pigment is optimized for infrared sorting of plastics and has the following characteristics:

  • Jet masstone color
  • Non-magnetic
  • Survives multiple extrusions
  • Single pigment solution
  • Widely listed on chemical registries for global supply
  • Food packaging compliance in key EU market

Black 10P925 is not only excellent for coloring plastic articles used for producing, packaging and transporting food, but can be used in other coatings as well. This new pigment is an example of Shepherd Color’s R&D expertise in developing products that provide unique tools to solve the challenges of customers in the coatings and plastics industries.
