Washable Labels Powered by Water-based Adhesives: Safeguarding High-Quality "Bottle-to-Bottle" PET Recycling

Safeguarding a Green Future

In the global effort to address climate challenges and plastic pollution, Sinograce Chemical remains steadfastly focused on the R&D and innovation of surface material products. We are committed to driving the circular economy through sustainable chemical solutions, helping the industry realize a bright, green, and low-carbon future.

In this vast and long-term environmental undertaking, the recycling rate of plastic packaging stands as one of the key factors determining the effectiveness of the circular economy. As a specialized supplier in the field of water-based adhesives, Sinograce Chemical has specifically developed and launched a series of products—including the WM549 Water-based Label Film Adhesive—designed to target core pain points in the recycling process and to build a high-quality, high-value PET recycling loop.

Effortlessly Separating Labels from PET Materials: Solving the Challenge of Downcycling

A significant volume of recycled PET material is currently "downcycled"—relegated to lower-value, non-circular products—due to contamination by impurities. Only a minuscule fraction of recycled PET is ultimately reused to manufacture new bottles.

The root cause of this issue lies in the fact that large quantities of PET flakes retain residual impurities—such as labels, inks, and adhesives—that are notoriously difficult to remove completely. Consequently, PET materials that are theoretically capable of high-quality circularity are regrettably forced into a destiny of "downcycling."

Sinograce WM549 Water-based Label Film Adhesive: A Washable Solution Tailored for PET Bottle Recycling

To address this critical industry pain point, Sinograce Chemical has introduced the SA-233 Water-based Label Film Adhesive. During the alkaline washing phase of the recycling process, this adhesive enables rapid and complete separation from PET flakes. It perfectly resolves contamination issues caused by residual labels, inks, and adhesives, thereby enabling a truly high-quality, "bottle-to-bottle" PET recycling loop.
