Upgrading White rPET for Circular Packaging
Additive designed to upgrade white opaque rPET (rPETo), supporting closed-loop recycling
in UHT and ESL dairy packaging applications.
Closing the Circularity Loop of White rPET
White recycled polyethylene terephthalate (rPET) is a promising material for use in circular white light-blocking applications and to aid in reaching recycling targets. The white rPET stream is becoming more and more available, thereby allowing for full circularity for white PET dairy bottles. However, it faces challenges that hinder its widespread adoption:
- Opacity and Color: White rPET lacks the desired opacity and tends to be too dark. Achieving the right balance is crucial.
- Regulatory Goals: The EU mandates increasing rPET content (25% by 2025, 30% by 2030). How do we use the white rPET stream to meet these targets effectively?
- Additive Dilemma: Using higher white rPET content requires using more additive, but overshooting the light barrier properties can be a concern. So how can you optimize for the best results?
Introducing Holcopearl ReWhite
Our mono-material solution for PET bridges the gap between performance, compliance, and circularity:
- Restores whiteness and brightness, counteracting greyness and L* loss typical of rPETo streams.
- Improves light protection, allowing recycled bottles to meet UHT/ESL shelf-life requirements.
- Enables up to 50% rPETo content while maintaining both aesthetic and functional performance.
True closed-loop recycling for rPETo?
White opaque PET (rPETo) is one of the most challenging material streams in the PET recycling system. During reprocessing, rPETo typically becomes greyer, loses *brightness (L)**, and shows a decline in light-protection performance. Watch the video to learn more.
See the difference
Below you can see two actual bottles with rPET, one has been created with HolcoPearl ReWhite and one has not. As you can see, there's a clear and distinct color difference.
