Silicon dioxide as a film opening agent
In recent years, driven by the demand for innovation in the packaging industry, the transformation of packaging solutions in the food and beverage industry, technological advancements in the electronics industry, and the growing public interest in environmentally friendly and sustainable materials, the high transparency film market is experiencing unprecedented growth opportunities.
From lightweight and durable packaging materials to protecting sensitive electronic components, the application range of high transparency films is becoming increasingly wide, and their market demand is constantly rising worldwide.
According to the analysis of Data Bridge Market Research, the global market value of high transparency films is expected to reach $636.51 million in 2023, and is projected to reach $954.82 million by 2031, with a compound annual growth rate of 5.20% during the forecast period from 2024 to 2031.
Excellent opening effect: ultra-high specific surface area, effectively preventing film adhesion
Silica used as an opening agent has an ultra-high specific surface area and pore structure. Adding it to plastic film can adsorb the end chains of film molecules, reduce entanglement between molecular chains, increase the roughness of the film interface, improve the film opening, effectively prevent adhesion, and facilitate film unwinding.
Improving the opening performance of the film can ensure that the film is easy to separate during processing, packaging, and use, prevent production efficiency and product appearance from being affected by adhesion, reduce electrostatic adsorption, and improve user experience, meeting the market's demand for fast packaging assembly lines.
High transparency: refractive index similar to resin, low salt and iron content
Synthesize amorphous silica with a refractive index similar to that of commonly used resins in the plastic industry, which can reduce light scattering at the interface between plastic films and opening agents, reduce haze caused by scattering, and maintain the transparency of the film.
A lower salt content and iron content mean that there are fewer impurities in the silica opening agent, which helps to reduce impurities in the film, thereby reducing the impact on the transparency and haze of the film.
Excellent dispersibility: effectively controlling the crystal points of thin film processing
The generation of crystal dots during the production and manufacturing process of thin films can significantly affect the appearance of transparent films. Effective control of crystal points is one of the major challenges in the processing of plastic films, especially in the processing of multi-layer co extrusion technology films, where crystal point control is even more difficult.
In addition to industry, film products are widely used in food packaging, such as oily foods, sugary foods, fast food, beverages, and fruits and vegetables. Food grade films play an important role in reducing food oxidation and maintaining food freshness.
