Characteristics and Application Analysis of Perforated Window Vinyl Film

Unique structure lays the foundation for function
Perforated window vinyl film is often called one-way perspective sticker, and its structure is exquisitely designed. It is mainly composed of black and white composite PVC film, which is widely used in the field of material science. PVC is polyvinyl chloride, which is synthesized through a specific process and has good flexibility and plasticity. In perforated window vinyl film, the combination of white surface material and black adhesive is the key. The white surface material bears the heavy responsibility of visual communication. With its good reflection performance of light, it clearly shows the patterns and texts it carries. The black adhesive layer plays the role of pasting and fixing. Due to its color characteristics, it gives the film a sunshade function. From a physical principle point of view, black can absorb a lot of light, reduce the amount of light that enters the room or car through the film, and effectively reduce the light intensity. The semi-removable or removable glue coated on the film brings great convenience to its use. When the film needs to be replaced, it can be easily removed without damaging the glass surface. The single or double-layer composite paper lining on the back protects the glue layer during the storage and transportation of the film, preventing the glue from being contaminated with impurities, and ensuring that the film can maintain good adhesive properties when used. ​

Diverse applications meet the needs of different scenarios​
Perforated window vinyl film is widely used in many fields. In the field of architecture, this film is widely used in glass curtain wall decoration. The application of perforated window vinyl film can provide sufficient natural light inside the building, meet people's needs for bright indoor environment, and present a unique visual effect on the outside of the building. It can be an exquisite advertising pattern used to promote the brand image of commercial buildings; it can also be an artistic design to add a cultural atmosphere to the building. ​In the field of transportation, it is indispensable for the window decoration of subways, buses, trucks and other means of transportation. For subways and buses, the perforated window vinyl film on the windows can display line information, city propaganda posters and other content, and become a flowing landscape of the city during the driving process of the vehicle. For trucks, the use of film can not only display the company logo and product information on the body, but also play an advertising role. The sunshade effect brought by its black adhesive can also protect the goods in the car from direct sunlight to a certain extent, extending the shelf life of the goods.

Significant performance advantages create market competitiveness​
From the perspective of vision and privacy safety, perforated window vinyl film provides clear visual communication on one side, and the black adhesive on the other side realizes the functions of sunshade, privacy and security. Indoors, people can clearly see the outdoor scene through the film and enjoy a wide field of vision; while outdoors, due to the obstruction of the black adhesive, it is difficult for the outside world to see the indoor situation clearly, protecting the privacy of the people indoors. In some places with high security requirements, its security advantage is more prominent, which can effectively prevent outside peeping and reduce security risks. ​Economical practicality is also a major advantage. Compared with some high-end glass films or sunshade equipment, perforated window vinyl film is affordable.

Durability and adaptability to medium- and short-term applications​
The durability of perforated window vinyl film is usually within 1 year. This feature determines that it is mainly suitable for medium- and short-term application scenarios. Its durability is affected by many factors, including external environmental factors such as ultraviolet radiation, temperature changes, and wind and rain erosion. Long-term ultraviolet radiation will age the PVC film, causing the color to fade and the material to become brittle; drastic changes in temperature will cause the film to expand and contract, affecting its adhesion to the glass surface; wind and rain erosion may cause wear on the film surface. Frequency of use and cleaning methods will also affect durability. Frequent opening and closing of windows may cause friction between the film and the window frame, causing damage to the film; improper cleaning methods, such as using sharp tools or highly corrosive cleaners, will also accelerate the damage of the film. For many short- and medium-term application scenarios, such as seasonal promotions, temporary exhibitions, and decoration of short-term rental houses, durability within 1 year is fully sufficient to meet the needs.
