From stuck neck to domestic substitution: Bangyu Film, the game-breaker in the V0-level halogen-free flame retardant film track

Biaxially oriented polyester film (BOPET) is a polymer material with excellent comprehensive properties, and its application boundaries are constantly expanding with technological breakthroughs. From traditional packaging and printing to today's hot new energy power batteries, high-end consumer electronics, optical displays and even aerospace, BOPET films have become an indispensable key material for modern industry.

Since 2025, with the slowdown in the growth rate of the industry's supply side and the formation of a consensus on "anti-involution", the BOPET industry is ushering in a key turning point from "scale expansion" to "value creation". In this leap from low-end involution to high-end intelligent manufacturing, innovative companies that master core technologies and focus on high-performance films are becoming the backbone of rewriting the industry landscape.

Jiangsu Bangyu Thin Film Technology Co., Ltd., established in December 2020, stands on this historical trend at the right time. Since its establishment, Bangyu Film has abandoned the old path of low-end production capacity expansion and resolutely chosen the most difficult but most valuable "pyramid tip" - high-performance BOPET functional film.

As a technology-based enterprise with a planned annual output of 60,000 tons and four advanced production lines, Bangyu Film not only has the country's first wide-width thin BOPET assembly production line, but is also equipped with the industry's first set of fully intelligent automation devices. This not only achieves stable production of ultra-thin films, but also achieves a qualitative leap in production efficiency, laying a solid manufacturing foundation for breaking overseas technical barriers.
