Low-Surface-Energy PET Label

The Low-Surface-Energy PET Label is a specialized industrial marking solution engineered for substrates where standard labels fail to adhere. Its construction features a white matte polyester (PET) facestock with a coating optimized for heat transfer printing, paired with a high-tack acrylic adhesive system. This label is available in a 50 µm thickness and is designed to deliver reliable performance across a demanding temperature range of -40°C to 150°C. The facestock is specifically formulated to work with resin ribbons, ensuring that printed information remains crisp and durable over the product's service life.

Performance is anchored in the advanced SE100 adhesive technology, which provides exceptional bonding to difficult, textured, and granular surfaces with very low surface energy. This includes challenging materials like Polypropylene (PP), low-density Polyethylene (LDPE), and mineral-filled or fiber-reinforced composites. The adhesive’s high initial tack ensures immediate grip upon application, while its chemical resistance protects the label integrity in harsh environments. Furthermore, the label is designed to maintain stable barcode contrast, ensuring scannability throughout its lifespan. A double-sided release liner is incorporated to facilitate consistent die-cutting, improve production efficiency, and minimize issues related to adhesive overflow during the converting process.

This label is ideally suited for plastic housings, powder-coated parts, material handling bins, and automotive trim components where reliable identification is critical. Given the variability of industrial substrates, we strongly recommend adhesion testing on your exact material to confirm compatibility before full-scale deployment. If you are working with low-energy plastics or textured surfaces, this product offers a robust solution.
