Dry-Erase Whiteboard Self-Adhesive Pouch Manufacturing & Global B2B Supply
Welcome to Yixing Wangzhe Laminating Film Co., Ltd. (WONLAMI), a premier high-tech enterprise dedicated to the research, development, extrusion composite coating, and international distribution of high-performance functional polymer packaging materials. Founded in 1999, our enterprise brings over 25 years of specialized extrusion lamination experience to serve global commercial print managers, office stationery brand owners, educational supply distributors, and corporate training equipment providers across more than 40 countries. As leading Whiteboard Self-adhesive Pouch manufacturers, an advanced Whiteboard Self-adhesive Pouch factory, and a trusted supplier for Whiteboard Self-adhesive Pouch wholesale, we engineer innovative dry-erase self-adhesive film pouches that combine a high-hardness write-on wipe-off surface coating with a removable, washable, and repositionable pressure-sensitive adhesive backing, transforming any flat wall, door, desk, or filing cabinet into an interactive whiteboard display.
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 coating and laminating 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 A4/A3 dry-erase pouches, interactive classroom activity sheets, warehouse tracking boards, or custom-slit commercial rolls, our production infrastructure delivers micrometer-level gauge uniformity, short lead times, and factory-direct volume pricing.
Dry-Erase Surface Science & Removable Adhesive Polymer Mechanics
In modern corporate offices, school classrooms, healthcare facilities, and manufacturing plants, visual project boards, scheduling calendars, and team brainstorm charts are modified continuously throughout the day. Standard plastic laminating films protect underlying paper from moisture, but writing on them with dry-erase markers leaves stubborn ghosting, ink smudges, and permanent marker stains after repeated wiping. Furthermore, mounting standard laminated charts onto walls traditionally requires tape, pushpins, or permanent adhesives that damage interior wall paint, leave sticky residue, or fail under ambient humidity shifts.
To bridge document encapsulation with interactive writing functionality, WONLAMI engineered a specialized multi-layer polymer composite structure. The front face consists of an optical-grade Polyethylene Terephthalate (PET) film treated with a high-crosslink nano hard-coat that provides exceptional scratch resistance (3H rating) and zero-ghosting dry-erase performance (tested for 10,000+ write-and-wipe cycles). The inner core features a heat-activated Ethylene Vinyl Acetate (EVA) hot-melt layer that encapsulates paper documents smoothly, while the rear face is coated with a washable, removable acrylic pressure-sensitive adhesive protected by a siliconized release liner. Once applied to smooth surfaces—such as glass walls, painted drywall, wooden doors, or steel cabinets—the pouch adheres firmly without bubbling, yet peels off cleanly without leaving adhesive residue or tearing wall paint.
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 cold lamination media. For machine-free document encapsulation without electricity, Self-laminating Pouch delivers instant cold sealing, while Self-Sealing Laminating Pouch offers pre-folded pressure-sensitive ID card badges:
- High-Hardness Dry-Erase Nano Surface: Formulated with a specialized cross-linked hard-coat that withstands dry-erase marker friction, preventing ghosting, ink staining, and surface haze.
- Removable & Washable Adhesive Backing: Utilizes low-tack micro-suction acrylic adhesive technology that clings securely to walls, glass, and wood, peeling away residue-free and regaining stickiness after water washing.
- High Optical Clarity & Contrast: Base PET film delivers light transmittance exceeding 92%, preserving vibrant document color saturation and sharp text readability behind the whiteboard surface.
- Bubble-Free Lay-Flat Lamination: Specially formulated EVA adhesive layer melts uniformly under heated rollers (110°C to 135°C), eliminating air pockets, water ripples, and edge lifting.

User Operation Guidelines & Surface Cleaning Best Practices
To achieve bubble-free document lamination, secure wall mounting, and long-lasting dry-erase performance, users should follow these simple operational practices:
- Pouch Lamination: Place your paper calendar or template inside the whiteboard pouch and pass it through a pouch laminator set between 110°C and 135°C for a smooth, sealed finish.
- Surface Mounting: Peel off the siliconized backing liner and align the pouch on a clean, dry wall, glass partition, or door. Press firmly from the center outward to smooth out air bubbles.
- Dry-Erase Marker Usage: Use standard whiteboard dry-erase markers. Wipe clean using a soft microfiber cloth, felt whiteboard eraser, or damp sponge.
- Adhesive Washing & Re-Use: If the adhesive backing collects dust over time, simply peel the pouch off the wall, wash the adhesive backing gently with clean water, air dry, and re-apply to new surfaces.

Frequently Asked Questions (FAQ)
Q1: Why choose WONLAMI as your primary Whiteboard Self-adhesive Pouch factory and wholesale supplier?
WONLAMI brings over 25 years of specialized extrusion composite experience, operating two modern production bases in China and Thailand with 10 extrusion lines and an annual capacity exceeding 30,000 tons. We enforce strict ISO 9001 and ISO 14001 quality systems, providing global distributors with certified dry-erase performance (≥10,000 write-and-wipe cycles), residue-free removable adhesion, micrometer-level gauge uniformity, competitive factory-direct pricing, and flexible tariff-optimized shipping options.
Q2: Will the self-adhesive backing damage painted drywall, wooden doors, or glass partitions when removed?
No. WONLAMI utilizes specialized removable micro-suction acrylic adhesive technology. The adhesive forms a secure bond on smooth interior walls, glass, wood, and metal without leaving sticky residue, staining surfaces, or tearing interior wall paint when removed.
Q3: How do you clean the dry-erase surface, and what happens if dry-erase marker ink is left on for weeks?
Our dry-erase surface features a high-crosslink nano hard-coat that prevents ink absorption. Daily writing wipes clean easily with a dry felt eraser or cloth. If marker ink is left on the board for weeks or months, simply wipe with a damp cloth or mild glass cleaner to restore a pristine, ghost-free surface.
Q4: Can WONLAMI supply pre-printed whiteboard pouches, custom dimensions, and OEM retail packaging?
Yes. We specialize in custom B2B manufacturing, providing pre-cut whiteboard pouches in all standard dimensions (A4, A3, Letter, Legal, Photo), custom pre-printed templates (weekly schedules, Kanban grids, music staves), safety rounded corners, and full OEM private-label retail box packaging tailored to distributor specifications.
Q5: What international quality and environmental certifications back WONLAMI whiteboard pouch 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 dry-erase cycle durability, wall peel removability, optical transparency, and environmental aging prior to release.
