Description

Product Introduction

Transparent erasable film is a functional film made from high-quality PET as the core substrate, refined with a special erasable coating process. Some products can be combined with transparent pressure-sensitive acrylic adhesive or silicone removable adhesive, offering both high transparency and repeated erasability. Without altering the original color and appearance of the substrate, it transforms various smooth surfaces into flexible writing and erasing surfaces. With its advantages of high transparency, no residue, durability, and easy installation, this product is widely used in offices, schools, homes, advertising, retail displays, and many other scenarios. It is suitable for both DIY personalized use and large-scale commercial applications, making it a versatile and practical multi-functional film material.

     

Product Features

(I) High Transparency and Seamless Integration, Preserving Original Visual Effects

Utilizing a high-transparency PET substrate, the film boasts a light transmittance of over 95%. The material is clear and transparent, free from haze and yellowing. When applied to smooth surfaces, it is virtually invisible, perfectly preserving the original color, texture, and design details of the base material. It does not obstruct vision or compromise overall aesthetics. Whether applied to glass, acrylic, office desks, furniture surfaces, or overlaid on photographic prints, maps, or decorative panels, it achieves an “invisible writing” effect, combining writing functionality with visual integrity. This solves the problem of traditional whiteboard films obscuring the underlying color and is suitable for various scenarios requiring high transparency. The film surface is smooth and flat, free from scratches and impurities, providing a smooth writing experience without any sticking or dragging.

(II) Durable and Long-Lasting, Repeated Writing Without Residue

The surface features a special erasable coating with strong adhesion and excellent wear resistance. It is compatible with various whiteboard pens and water-based markers, providing smooth and effortless writing with clear and distinct lines. Cleaning requires no special wipes or alcohol; a regular tissue or dry cloth is sufficient for easy cleaning, leaving no ink marks, graying, or residue. It can withstand over 100,000 cycles of repeated writing and erasing, maintaining its transparency and cleanliness even after long-term use, without issues such as coating peeling, lifting, or blurring. Furthermore, the coating possesses excellent stain resistance, weather resistance, and chemical resistance, resisting mild solvents and diluted acids and alkalis. It offers a durability of 5-7 years for indoor use and 3-5 years for outdoor vertical applications (depending on the exposure environment).

(III) Easy Installation, Removable and Adjustable Without Leaving Traces

The back can be customized with transparent removable adhesive or electrostatic adsorption design, requiring no professional tools or complex procedures, making it easy for even beginners to install. The removable adhesive version uses high-quality acrylic or silicone adhesive systems, offering moderate tack and stable peel strength. It allows for repeated repositioning during application, minimizing bubbles and wrinkles, and provides a secure, non-peeling bond after application. Removal requires no heating or chemical agents; it can be easily peeled off without leaving residue or damaging the substrate surface. It can be reused multiple times without losing adhesive strength, making it ideal for temporary displays and frequent changes. For large-area applications, wet installation (using water and detergent) is recommended to effectively prevent bubbles and ensure a smooth application. The electrostatic adsorption version requires no adhesive and can be directly adsorbed onto smooth surfaces such as glass, making installation and removal even more convenient.

(IV) Environmentally Friendly and Safe, Suitable for Various Scenarios

Adhering to environmental principles, the product uses a PVC-free formula, selecting non-toxic, odorless, and VOC-free base materials and coatings. It is free of heavy metals, PFOA, PFOS, and other harmful substances, complying with EU OEKO-TEX Class II environmental standards and US ASTM Class A fire resistance standards. It can be safely used in children’s rooms, classrooms, hospitals, food retail, and other scenarios with high environmental requirements, and can even be used for auxiliary displays related to baby clothing. Furthermore, the product is recyclable, and proper disposal after use will not pollute the environment, combining practicality and environmental responsibility.

(V) Flexible Specifications, Customizable to Meet Diverse Needs

Supports various specifications and process customizations. Base material thickness options include 50μm, 75μm, 80μm, 100μm, etc., with widths up to 1.5m and lengths customizable according to requirements (from small A4 sizes to large 100m rolls). The surface can be made in glossy or matte finishes – the glossy version offers greater transparency, suitable for advertising displays and glass decoration; the matte version effectively prevents glare, suitable for writing, teaching, and office environments. In addition, printing compatibility can be customized to meet various needs, supporting UV inks, solvent inks, weak solvent inks, and latex inks. It can be used for digital printing and screen printing to create erasable advertisements, map whiteboards, art whiteboard wallpapers, and other personalized products, adapting to the customized needs of different industries.

 

Application Scenarios

Core applications include: office environments (desks, glass partitions, supplementary surfaces for meeting whiteboards, and memo posting); educational settings (classroom glass surfaces, desks, and blackboard edges, creating flexible writing areas); home environments (refrigerators, wardrobes, glass doors and windows, for leaving messages, taking notes, and doodling); and retail settings (shop windows, product display cases, for temporary pricing and promotional messages). This product is easy to use and cost-effective, making it the most widely used type on the market, meeting the daily needs of individuals, small offices, and families.

Instructions for Use

1. Surface Cleaning: Thoroughly clean the surface to be pasted using a dry cloth or a damp cloth dipped in diluted detergent. Remove dust, oil stains, water stains, and other impurities to ensure the surface is smooth, dry, and free of unevenness. This prevents poor adhesion and bubble formation. If there are paint residues on the surface, gently remove them with a mild abrasive cleaner or a blade.
2. Cutting and Trimming: According to your needs, cut the erasable film to the corresponding size using scissors, a utility knife, or an electronic cutting machine. Leave a 1-2mm margin during cutting for easier adjustment and to prevent the edges from lifting due to undersizing.

3. Pasting and Installation: For small areas, use the dry application method. Gently peel off the backing film, align one end of the film with the desired position, and slowly smooth it out, pressing from the center outwards to remove air bubbles. For large areas, the wet application method is recommended. Evenly spray a mixture of water and detergent onto the cleaned surface. After peeling off the backing film, apply the film to the wet surface, adjust it to the correct position, and use a squeegee to wipe from the center outwards, removing water and air bubbles to ensure a smooth application.

4. Writing and Use: After pasting, let it sit for 1-2 hours (24 hours for the wet application method to ensure complete water evaporation). You can then write on it with a whiteboard marker or water-based marker. After writing, gently wipe it clean with a dry cloth or tissue. It can be used repeatedly.

5. Removal and Replacement: If removal or replacement is needed, gently pinch one corner of the film and slowly peel it upwards for complete removal. After removal, wipe the surface with a damp cloth to remove any remaining residue (removable adhesive versions leave almost no residue). If you need to reuse it after removal, wipe the adhesive surface clean and store it in a sealed container.
