Firsta Group has completed validation testing of its independently developed high-barrier ILC-BOPP coated base film, with key performance indicators meeting the required targets at 150°C. The results mark a further development of ILC-BOPP technology for applications requiring elevated-temperature performance.

Firsta’s ILC-BOPP production line, developed in cooperation with Brückner, officially entered operation on 18 October 2025. It is the first industrial-scale ILC-BOPP production line of its kind in China, marking an important step in the commercialization of inline coating technology in the domestic market.

Thomas, Global Electrical Director at the Brückner Group, said: “As part of our cooperation with Firsta Group, we redesigned and manufactured a customized Brückner coating system based on Firsta’s specific requirements and the needs of the Global market. By integrating the coating process into the production line, the system significantly reduces energy consumption and enables zero VOC emissions.”

Unlike the conventional offline process, in which the film is first produced and then coated separately, ILC-BOPP integrates biaxial orientation of the polypropylene substrate with the application of the functional coating within the production process. This integrated approach is intended to simplify the manufacturing process while enabling the development of films with enhanced temperature resistance, barrier performance and other functional properties.

Firsta has established an integrated functional-film production platform covering BOPP, BOPET, coating, metallization and masterbatch. Its high-barrier ILC-BOPP films are already in batch production for applications including food packaging, pharmaceutical and medical packaging, electronic component protection and new energy materials.

The newly validated temperature-resistant ILC-BOPP base film is being developed for applications where both thermal resistance and barrier performance are required. It provides an additional polypropylene-based material option for demanding packaging and functional-film applications.

Firsta said it will continue to advance the temperature-resistant ILC-BOPP technology toward industrial-scale production while further developing high-performance functional films for applications requiring enhanced barrier and thermal performance.
