SIBUR Develops New Livestock Ear Tag Using EVA+LDPE Composite Material

SIBUR has developed Russia's first composite material solution based on ethylene-vinyl acetate (EVA) and low-density polyethylene (LDPE) for the production of livestock ear tags. This innovative solution enables the industrial production of plastic identification tags for animal ears. Such ear tags, which carry individual information, are currently the most humane method of animal identification.

The finished products made from this new type of composite material have characteristics such as high strength, wear resistance, good flexibility, anti-trauma, and low allergenicity. Solutions based on EVA and LDPE possess excellent flow properties, allowing for easy demolding, uniform pigment distribution, and geometric dimension stability, while ensuring high clarity of laser marking. Compared to the traditional thermoplastic polyurethane (TPU) used in ear tag manufacturing, the new solution eliminates the need for raw material drying, thereby shortening the production cycle and reducing overall costs.

Vasily Mashukov, Director of Application Development at SIBUR PolyLab Research Center, stated: "SIBUR's R&D portfolio covers more than 20 projects aimed at the Agricultural Industrial Complex (AIC) and over 40 products. Advanced solutions made from modern synthetic materials help accelerate the modernization of livestock facilities and ensure livestock inventory. The development of composite materials for animal ear tags is a prime example of how science and technology directly improve animal husbandry conditions and enhance agricultural operational efficiency."

It is predicted that during the 2028-2030 planning period, the use of polymer solutions in Russia's Agro-Industrial Complex (AIC) will increase by 72%. The application of domestically produced polymers opens up new opportunities for farmers, as it can reduce reliance on imports and support local manufacturers. In a constantly changing market environment, such alternative solutions are crucial for the sustainable development and competitiveness of Russia's Agro-Industrial Complex (AIC).

This composite material based on EVA and LDPE was jointly developed by SIBUR’s PolyLab research center in Kazan, Russia, and Nizhnekamskneftekhim, with support from the ear tag manufacturer ISBC.
