SINTREX®: the new benchmark in lightweight, recyclable PET panels
For responsible Visual Communication, the choice of material defines both performance and purpose. As brands seek PVC-free and more circular alternatives, a new generation of substrates is emerging. Among them, SINTREX® marks a turning point.
For responsible Visual Communication, the choice of material defines both performance and purpose. As brands seek PVC-free and more circular alternatives, a new generation of substrates is emerging. Among them, SINTREX® marks a turning point.
Developed by 3A Composites and distributed by Antalis, this expanded PET sheet combines the strength and print quality professionals expect with the environmental credentials demanded by today’s market. Rated 3 stars in the Antalis Green Star System™, it proves that technical performance and circular design can go hand in hand.
SINTREX®: the PET innovation for demanding applications
Both lightweight and rigid, resistant and easy to process, SINTREX® offers everything printers and display manufacturers need in a premium visual-communication substrate.
- High print quality
Its natural white surface offers excellent printability on most standard printing technologies with optimal colour rendering. It’s a perfect fit for printers and display manufacturers seeking both creative flexibility and environmental progress.
- Lightweight and easy to handle
With a density of around 340 kg/m³, SINTREX® provides the durability of a structural material with the workability of a lighter sheet. It simplifies handling, reduces transport costs, and shortens installation time — a clear logistical advantage for large format applications.
- Outdoor durability and fire-resistance
Designed for both indoor and outdoor use, the panel resists moisture and UV exposure while maintaining dimensional stability. Its fire classification (EN 13501-1 B-s1,d0 at 5 mm / B-s2,d0 at 10 mm) meets the strictest safety standards for public spaces.
- Easy and precise processing
Unlike multi-layer composites, SINTREX® is a mono-material sheet made entirely from PET. Its uniform structure makes the sheet easy to cut, mill, drill, or thermoform; a key advantage for complex POS displays or decorative elements. Its mono-material composition also simplifies recycling.
- Recyclability at the core
SINTREX® is made from a single polymer family−PET, one of the most widely recycled materials in the world. This mono-material design makes its end-of-life management simpler and more transparent.
3A Composites also integrates production waste back into the manufacturing process, reducing the use of virgin raw materials and optimising resource use. The result is a lower overall carbon footprint without compromising performance.
By switching from PVC to SINTREX®, printers can significantly reduce CO₂ emissions and material mass per square metre — key metrics in tenders and sustainability audits. In short, it’s a high-performance panel designed for a more circular economy.
The Green Star System™: making more sustainable choices
Antalis created the Green Star System™ to help customers quickly understand the environmental profile of each Visual Communication material. Rated from 1 to 5 stars, this internal tool evaluates key criteria such as recyclability, recycled or bio-based content, production origin, and end-of-life options to make it easy for customers to compare different alternatives for one particular application.
How does SINTREX® score in the Green Star System™?
With its 3-star rating, SINTREX® demonstrates a strong environmental performance within the Visual Communication category.
This transparent rating system has become a practical reference for printers and brands alike who want to meet growing ESG and regulatory requirements.
It allows professionals to justify material choices in sustainability reports or client audits, while making eco-responsibility more visible in the value chain. It’s easy to use as a communication tool, mentioning: "Our material is 3-star rated in the Green Star System™ ."
Antalis: guiding the transition to PVC-free materials
Through its Visual Communication portfolio, Antalis supports PSPs and brands in transitioning toward PVC-free and recyclable substrates.
Beyond SINTREX®, the company’s Ecobox sampling tool offers a curated selection of alternative materials — paper-based, polypropylene, and more — designed for testing and comparison.
Antalis experts accompany each client throughout the entire process: assessing print compatibility, durability needs, and recycling options. This consultative approach ensures that sustainability is not just a checkbox but a performance factor integrated into every campaign.
Whether for indoor displays, outdoor signage, or retail decor, SINTREX® is part of a wider movement where eco-design becomes a creative enabler. By combining 3A Composites’ innovation with Antalis’ expertise in responsible sourcing, the material helps redefine what high-quality Visual Communication looks like in a more circular economy.
Conclusion: setting a new standard for responsible creativity
By merging the technical excellence of expanded PET with improved recyclability, SINTREX® sets a new benchmark for professionals seeking performance without compromise.
Lightweight, durable, and easy to recycle, it stands as proof that innovation and circularity can advance together. With the Green Star System™ as a trusted indicator, Antalis gives its clients the tools to create, communicate, and reduce their footprint.
Because every printed message deserves a responsible medium.
