Polarizers, as key "optical switches" for liquid crystal displays (LCDs) and even some OLEDs, directly determine the brightness, contrast, color, and lifespan of the screen based on their performance. This seemingly simple "sandwich" structure (TAC protective layer/PVA polarizing layer/TAC protective layer/functional adhesive/PET release film) actually embodies cutting-edge technologies such as polymer physics, precision coating, optical design, and chemical treatment.

Recently, led by Guilin Electric Science Research Institute Co., Ltd. and with the deep participation of Jiangsu Xinyi Film Co., Ltd., the world's first BOPLA film dedicated production line has completed multifunctional biaxial tensile testing, main assembly, and other work. It is about to enter the joint debugging and testing stage. During the testing period, the BOPLA film produced by the equipment meets EU and national standards in terms of biodegradability, and has been audited by authoritative certification and testing institutions at home and abroad.

On the track of "high-temperature luminescence" in flexible photoluminescent materials, the team led by Zhang Kun from Xi'an Engineering University has published their latest work in Advanced Optical Materials, pushing the temperature resistance limit of flexible visible luminescence to 375 ℃, and for the first time, using X-ray full scattering measurement to capture high-definition close-up of the microstructure of amorphous ceramic nanofibers through the "flexibility+high-temperature luminescence" mechanism.

In this study, an economical and efficient sol gel method was proposed to prepare nano porous silicon dioxide (SiO ₂) films with both high transmittance and super hydrophobicity to improve the efficiency of solar cells.

Optical thin films are ubiquitous in modern technology, from mobile phone lenses to precision lasers, from high-definition displays to high-efficiency solar cells. Their performance directly affects the performance of the final product. The key to determining the quality and production efficiency of optical thin films lies in the core equipment used in their production process. Today, let's talk about the core technologies and future development of these key devices.

The "number of layers" of co extruded film is not simply a numerical difference, but an intuitive reflection of material combination, functional integration, and performance performance. The 9-layer co extruded film has an additional 2-layer structure compared to the 7-layer structure, which brings about an essential upgrade in material design flexibility, functional segmentation ability, and application scenarios.

In today's increasingly stringent packaging performance requirements in industries such as food, medicine, and electronics, multi-layer co extruded films have become the mainstream choice in the market due to their excellent barrier properties, mechanical strength, and environmental characteristics. As a professional co extrusion film manufacturer with 7-9 layer blowing equipment (maximum width of 2.2 meters), we are committed to providing customers with 'high-performance, customized' packaging solutions through symmetrical and asymmetrical structural design, helping enterprises seize market opportunities!  

In the packaging industry, a good film material is not only the "protective layer" of the product, but also the "secret weapon" for enterprises to reduce costs and increase efficiency! As a practical practitioner who has been deeply involved in the co extrusion film field for many years, today we will take you to unlock the "Full Scene Co Extrusion Film Solution" - from bottom blown water-cooled 7-layer barrel film to top blown symmetrical/asymmetrical structural film, how can the 7-layer/9-layer core technology break through traditional bottlenecks and make packaging "tough, material saving, and adaptable to the whole industry"?

In today's world where food packaging pursues "180 day freshness lock", pharmaceutical packaging strictly adheres to "sterile standards", and electronic packaging urgently needs "anti-static black technology", the performance upgrade of multi-layer co extruded film has become a core proposition in the global flexible packaging industry. Koes Chemical has accurately identified market pain points and launched CF420 multi-layer co extrusion special adhesive, which uses revolutionary technology to solve the three major difficulties in the industry and redefine the bonding standards for co extrusion films.

This paper focuses on colorless nano high transmittance and anti reflection AR glass, systematically explaining its optical principles, performance advantages, application fields, and innovative preparation methods. By studying the design of nanoscale materials and multilayer film structures, the low reflection and high transmission characteristics of glass in the visible light band can be achieved, effectively solving the problems of high reflectivity and insufficient transmittance of traditional glass. In this paper, the preparation processes such as magnetron sputtering method and sol gel method are introduced in detail, and the influence of process parameters of each method on the film performance is analyzed, which provides theoretical and practical basis for the research and development and industrial application of colorless nano AR glass with high transmittance and antireflection.

Eliminating the solvent drying process, shortening the production cycle by 20%, reducing overall costs by 15% -20%, and adapting to the latest revised five layer co extrusion blown film unit standard in Guangdong Province (screw length to diameter ratio of 32:1, die diameter of 550mm).

Abstract: This paper conducts in-depth research on anti reflection films for solar cells, aiming to design efficient anti reflection films to improve the photoelectric conversion efficiency of solar cells.
