Guna Technology closes Series C for high-end thin films
What's the deal? Guangdong Guna TechnologyDealroom has a profile for this one. Try Dealroom → has raised a Series C round, the company announced in October 2026. Investors include Guochuang Venture Capital and Qinglan Huachuang. The amount and valuation were not disclosed.
What does the company do? Guna, incubated by a research team from the Hong Kong University of Science and Technology, develops multifunctional high-end thin films. It says its products have reached consumer electronics, new energy, and medical applications, and have passed validation and shipped in volume to leading industry customers.
Why now? Guna's previous disclosed round closed in March 2025, backed by Hongnuo Capital and Zhongren Huiyin, also without a stated figure. A Series C less than two years later signals continued fundraising momentum, though key terms remain undisclosed.
What's the endgame? The company has positioned itself as a platform business built on proprietary film-processing technology. Earlier funding went toward expanding capacity and pushing into higher-end applications — the test now is whether Guna can turn customer validation into stable, large-scale delivery.
The signal: High-end functional film materials keep drawing capacity investment: Deguan New Material recently announced an expansion project worth about US$57.8M for electronic and new-energy films, while Wanwei plans to invest in optical film capacity. Guna's round fits that trend, but without disclosed amounts or new capacity plans, it is too early to read it as a clear shift in competitive standing.
