How to judge smart PDLC film quality as a buyer?
We heard some clients is complaining the smart film quality problems like smart film is with bubbles, becoming degrading, not working anymore, etc .How that happens? I decide to write an article to help the importers and buyers to make the right decision when purchase, to lower down the unknown risky in the future. It’s only for reference,
Smart PDLC film is a high-tech product which is based on PDLC liquid crystal technology. It’s a switchable film composed of two layers of ITO films and one layer of PDLC.
Smart film production requires huge funds to support its R&D, machinery, manufacturer and factory built, so the original factory is few around the world.
Regarding smart film quality, there many reasons, the key factor might be its machinery, material, liquid crystal technology matured or not.
From the smart film structure, it requires at least Roll to Roll coating machinery ,liquid crystal lamination machinery, slitting machinery, cutting machinery; PET film material and liquid crystal technology. Each of them are required top quality one to manufacturer PDLC film. In the following we’ll share you the 5 ways to judge smart film quality.
5 ways to know smart film quality
Let’s talk about the 1st factor, ITO film roll to roll coating machinery, the high-tech machinery is manufactured in Japan, Taiwan, USA, Germany, Korea. In China, what are the manufacturer are using which brand for ITO film Roll coating. Uniteglass film Manufacturer imported the world-class high quality manufacturing roll to roll coating system from Germany Applied Materials. It’s around 10 million USD. This machinery rank top affecting smart film quality.
With the support from China Glass Industry Design & Research Institute, consciously improving smart PDLC film quality.
The conductive ITO film is widely used in smart touch screen like mobiles, pads, etc. we offered. This one of the way to know its ITO film quality too,
Smart film ITO film Coater
Liquid crystal technology and Liquid crystal lamination are the 2nd affect PDLC film quality. 90% China’s manufacturer is only processing this part with less funds without manufacture ITO film.
Different supplier offered quality is different, the lamination density, adsorption capacity differs, which causes smart film degrading, bubbles along with time.

The 3rd important factor is the raw material of smart film. Uniteglass raw material of ITO film imported Japan for its durable, clear, good flexibility temperature ,etc. However other are using mainland one. So we’ll see the difference, why some smart films is becoming yellow along with time.
The 4th factor is the working environment, it has to be 1000 grade dust-free and thermostatic workshop to guarantee its quality. If not manufactured with strict environment, it might causes some problem like circuit burnt of smart film, without switch on/off function, which there’s dust inside the coating and lamination process.
The 5th factor is the smart film cutting& bus bar wiring not handled by professional cutting machinery and matured staff, that might causes smart film not working or circuit burnt, edges damaged, etc.
Above 5 reason are the main factors affect smart film quality before delivery. Thus we sincerely advise each buyer/importer work with original manufacturer who owns the technology to improve quality, manufacturer ITO film, liquid crystal lamination to final smart film cutting with funds support.
As uniteglass PDLC films is manufactured by Anhui Fangxing Optoelectronic New Material Technology Co., Ltd, which is the benchmark of quality in China, its mother factory belongs to China building material group, a 500 fortune company. Stock Code: 600552. It owns all the machinery, technology, with stable staff, funds to go further in smart film quality improving and manufacturing,

China market is complex with different prices and quality, we hope the buyers shift smart film business to lower prices suppliers with workable smart film and ignore the future risky,
