China Writing film Manufacturer, Supplier, Factory

The main component is polyethylene terephthalate (PET), which is a thermoplastic polyester with high transparency, high strength and good chemical stability. The surface of PET film is usually coated with a special erasable coating, which is generally composed of organic polymer materials, pigments, additives, etc., giving the film the characteristic of erasability.

Appearance

• It has high transparency, can clearly transmit light, and has good visual effects. The surface is flat and smooth, without obvious flaws, bubbles or granularity, the film surface is clean and the color is uniform.

Performance characteristics

• Erasability: After writing on the film with a special writing tool (such as an erasable pen), the handwriting is clear and easy to recognize. Through a specific wiping method (such as using an eraser or a wet cloth, etc.), the handwriting can be easily erased, and there is no trace left on the surface of the film after erasing. It can be repeatedly written and erased many times, and has good abrasion resistance.

• Physical properties: PET film itself has high tensile strength and toughness, is not easy to tear and break, can withstand a certain degree of stretching and bending, and is suitable for a variety of application scenarios. At the same time, it has good wear resistance and can resist friction and scratches in daily use.

• Chemical stability: It has good chemical resistance and can resist the erosion of chemicals such as acids, alkalis, and organic solvents. It is not easy to deform, discolor, or degrade due to contact with common chemicals.

• Thermal stability: It has good thermal stability within a certain temperature range, can withstand a certain degree of high temperature, and is not easy to deform or change performance at room temperature or general use environment.

Application areas

• Writing and drawing: It can be used as an erasable writing board, drawing board, etc., and is widely used in schools, offices, homes and other places to facilitate temporary writing, recording and drawing, and reduce paper waste.

• Labels and logos: It is used to make reusable labels, such as product labels, logistics labels, etc. The information on the label can be changed at any time as needed to improve the efficiency and economy of label use.

• Electronic equipment: As a protective film for the screen of electronic equipment, it can not only protect the screen from scratches and wear, but also allow temporary writing or marking on it without affecting the display effect of the screen, and no traces will be left after erasing.

• Packaging field: It can be used for some packaging materials that need temporary information marking, such as food packaging, medicine packaging, etc., to facilitate information marking and modification during the packaging process.

Environmental characteristics

• PET material itself can be recycled and reused, meeting environmental protection requirements. Erasable PET film reduces the use of disposable writing materials such as paper, which helps save resources and protect the environment. At the same time, its erasable characteristics allow information to be modified and updated multiple times, reducing waste generated by information changes.
