Dry-Erase Whiteboard Cold Laminating Film Manufacturing & Global B2B Supply
Welcome to Yixing Wangzhe Laminating Film Co., Ltd. (WONLAMI), a premier high-tech enterprise dedicated to the research, development, precision coating, pressure-sensitive adhesive technology, and international distribution of high-performance functional polymer materials. Founded in 1999, our enterprise brings over 25 years of specialized composite lamination experience to serve global commercial print managers, office stationery manufacturers, educational equipment suppliers, display board convertors, and sign makers across more than 40 countries. As leading Whiteboard Cold Laminating Film manufacturers, an advanced Whiteboard Cold Laminating Film factory, and a trusted supplier for Whiteboard Cold Laminating Film wholesale, we engineer high-performance, room-temperature dry-erase cold laminating roll films constructed with high-transparency Biaxially Oriented Polyethylene Terephthalate (PET) base film featuring a specialized stain-resistant dry-erase surface treatment, coated with premium pressure-sensitive acrylic adhesive, and paired with a smooth release backing liner, delivering fast-drying marker writing without ink shrinkage, effortless dry-wipe erase performance without ghosting, room-temperature application without heating equipment, and permanent protective encapsulation for flexible writing surfaces, planners, wall charts, and educational whiteboards.
Our manufacturing operations span two modern intelligent production bases strategically located in Yixing, Jiangsu Province, China, and Rayong, Thailand. Covering a total land area of 135 mu with over 90,000 square meters of standardized clean industrial facilities, our dual-base infrastructure operates 10 advanced extrusion and precision coating lines, 29 high-speed automatic slitting machines, 2 multifunctional die-cutting units, and 4 fully automated packaging lines. Supported by a dedicated workforce of over 300 skilled technical professionals, our annual production capacity exceeds 30,000 metric tons. Whether your procurement demands standard dry-erase roll stock, custom roll widths up to 1800mm, silicon release paper or clear PET release film backing, or specialized core configurations (25mm, 58mm, 76mm), our production infrastructure delivers micrometer-level gauge uniformity, short lead times, and factory-direct volume value.
Dry-Erase Surface Science & Pressure-Sensitive Acrylic Mechanics
In modern corporate conference rooms, educational classrooms, home office planning centers, and industrial shop-floor scheduling boards, converting rigid wall spaces, printed posters, or foam boards into reusable interactive writing surfaces is a growing commercial requirement. Traditional rigid porcelain whiteboards are heavy, costly to ship, difficult to install on curved walls, and prone to surface chipping over time. Conversely, applying low-grade plastic film overlays leads to ghosting ink stains, marker ink contraction or bead-up, and adhesive bubbling during installation.
WONLAMI Whiteboard Cold Laminating Film solves writing performance and installation challenges through a multi-layer functional polymer architecture. The surface layer utilizes high-clarity optical PET film enhanced with a crosslinked hard-coated resin formulation that maintains precise surface energy. When writing with standard water-based or dry-erase whiteboard markers, the ink wets evenly without shrinkage, edge contraction, or ink beading, drying rapidly into clear, sharp text. After weeks or months of display, the smooth surface structure allows dry cloth or felt eraser wiping without ghosting, ink shadow staining, or chemical cleaning sprays. The reverse side is coated with solvent-free, high-tack pressure-sensitive acrylic adhesive protected by a silicon release backing liner. During cold nip roller lamination at room temperature, the release film peels off smoothly, and the pressure-sensitive acrylic adhesive bonds instantly onto printed posters, foam boards, metal sheets, walls, or glass panels without heat distortion or warm-up waiting time.
To support diverse surface mounting, commercial printing, and specialized interactive display needs across global B2B sectors, WONLAMI manufactures a comprehensive portfolio of self-adhesive and roll lamination media. For thermal roll lamination applications using heat equipment, Dry Erase Thermal Laminating Film offers EVA hot-melt bonding, while Laser Cold Laminating Roll provides 3D rainbow diffraction, Crystal Clear Cold Laminating Roll Film delivers optical glass transparency, Hard Coating Cold Laminating Roll offers 3H scratch resistance, and Sticky Back Laminating Film provides peel-and-stick mounting support:
- Effortless Dry-Wipe & Zero Ghosting: High-density crosslinked surface coating allows 100,000+ write-and-erase cycles without ink ghosting, shadow stains, or surface degradation.
- Fast-Drying Ink Wetting Without Shrinkage: Engineered surface energy ensures dry-erase marker ink flows smoothly without line shrinkage, ink beading, or smudging.
- Room-Temperature Pressure-Sensitive Bonding: High-tack optical acrylic adhesive seals at room temperature without thermal rollers, preventing heat damage to digital prints and posters.
- Smooth Release Liner Peel & Bubble-Free Mount: Silicon-coated release backing paper or clear PET liner strips cleanly for fast, bubble-free application on flat and curved surfaces.

Cold Laminator Machine Calibration & Maintenance Guidelines
To achieve bubble-free, high-performance dry-erase cold lamination on commercial roll laminators using Whiteboard Cold Laminating Film, operators should follow these machine setting recommendations:
- Nip Pressure Calibration: Set uniform pneumatic nip roller pressure across the web to squeeze out micro air bubbles without stretching the PET substrate.
- Release Liner Separation: Ensure smooth, consistent rewinding of the silicon release backing paper on the laminator's liner take-up mandrel.
- Web Tension Management: Maintain balanced unwinding web tension to prevent film tunneling, diagonal wrinkling, or edge stretching.
- Dry-Erase Surface Maintenance: Use standard felt whiteboard erasers for daily wiping. For long-standing marker notes, clean with a damp microfiber cloth or isopropyl alcohol solution.

Q2: What is the main difference between Whiteboard Cold Laminating Film and Dry Erase Thermal Laminating Film?
Whiteboard cold laminating film uses pressure-sensitive acrylic adhesive that seals at room temperature without heated rollers, making it ideal for heat-sensitive digital posters, foam boards, and direct wall application. Dry erase thermal film uses EVA hot-melt adhesive requiring heated rollers (85°C to 115°C).
Q3: Do whiteboard markers erase cleanly from this film after drying for weeks without ghosting?
Yes. WONLAMI Whiteboard Cold Laminating Film features a crosslinked hard-coated dry-erase surface engineered to resist marker ghosting and shadow stains. Even after weeks of dry writing, text wipes clean easily with a standard dry cloth or eraser.
Q4: Can WONLAMI supply custom roll widths, release liner options, and OEM private-label packaging?
Yes. We specialize in custom B2B manufacturing, providing whiteboard cold laminating film in custom widths (200mm to 1800mm), thicknesses from 30mic to 150mic, paper or clear PET release liners, roll lengths up to 1000m, and full OEM private-label packaging tailored to distributor specifications.
Q5: What international quality and environmental certifications back WONLAMI whiteboard cold laminating products?
WONLAMI products strictly comply with global safety and environmental standard mandates. Our production systems carry official certifications for ISO 9001, ISO 14001, GRS (Global Recycled Standard), BSCI, REACH, RoHS, C-TPAT, and UL. Every production batch undergoes laboratory testing for 180° acrylic peel adhesion, release force, marker write-and-erase durability, and environmental aging prior to release.
