Manufacturing black rigid film recyclable and therefore sustainable.
Carbon black is one of the oldest and most commonly used pigments for coloring plastics black. However, carbon black also has some disadvantages: In the recycling process, carbon black prevents plastics from being detected by optical sorting machines based on near infrared (NIR). This means that black plastics colored with carbon black cannot be recycled and must instead be incinerated or landfilled.
Buergofol offers alternatives in this matter
can be recycled
more resource-friendly
less energy / material
Instead of films colored with carbon black, we offer products with better recyclability, resource conservation and at least the same color quality.
For this purpose, we use color pigments that have been optimized for the use in packaging. These pigments reflect NIR rays and thus allow reliable sorting of the colored plastics in material recycling facilities. It also has high color strength and opacity and meets food contact requirements.
There are therefore good reasons for replacing carbon black as a colorant for films.
The alternatives are not only more recyclable, but also more resource-efficient, as they consume less energy and material. They also offer high color quality and variety for different applications.
The time has come to say goodbye to carbon black and instead
to modern and sustainable pigments instead.
