Enhance rPET Clarity with Ventura Horizon’s Liquid Anti-Yellow Additive

As the global packaging industry moves toward more sustainable solutions, recycled PET (rPET) has become a leading material of choice. Yet, one common challenge persists: yellowing and discoloration caused by thermal degradation and contamination during the recycling process.
At Ventura Horizon Limited, we provide advanced liquid anti-yellow additive solutions designed to restore the clarity, brightness, and performance of rPET—helping converters, recyclers, and brand owners unlock the full potential of recycled plastics

Why Yellowing Happens in rPET

Recycled PET undergoes multiple melting cycles and often contains residual impurities. These factors lead to visible yellow, grey, or brown discoloration in the final product—especially at higher rPET content levels.

This not only affects visual quality but also limits acceptance in high-end applications such as:

• Clear beverage bottles
• Transparent containers and packaging
• Premium-grade PET films or sheets

Discoloration also negatively affects CIELab color values, particularly the b* (yellow) and L* (lightness) metrics.

What Is Liquid Anti-Yellow Additive?

Ventura’s liquid anti-yellow additive is a specially formulated solution dosed directly into PET resin during melt processing—such as extrusion, injection molding, or preform production.
Key Benefits:

• Neutralizes yellow and dull hues
• Enhances L* value (brightness) and reduces b* (yellow) shift
• Effective at low dosages (0.01%–0.05%)
• Food-contact approved (EU/FDA grades available)
• Compatible with both virgin and recycled PET
• No compromise on mechanical strength or process stability

This additive delivers optical brightening and thermal protection in one integrated solution—preserving clarity while improving processing efficiency.

How It Works

Our liquid anti-yellow additive works in two main ways:

1. Color Correction:
   A precise optical toning effect offsets unwanted yellowing by introducing controlled blue or violet undertones—resulting in clearer, brighter PET.
2. Thermal Stabilization:
   The additive helps protect polymer chains from further degradation during high-temperature processing. This contributes to improved Intrinsic Viscosity (IV) retention and reduces the risk of brittleness or poor mechanical properties.

Easy to Integrate into Your Production

Implementing Ventura’s liquid anti-yellow additive is straightforward:

• Dose with standard liquid dosing units (available on request)
• Fine-tune results through lab-scale trials using CIELab color data
• Achieve color consistency batch after batch
• Ensure regulatory compliance with food-grade applications

Our technical team provides full support—from dosage calibration to on-site production guidance—ensuring your transition to clear, high-performance rPET is smooth and successful.
