We offer a professional sample kit for USD 30, which includes three film grades (T6/T7/T8), a dedicated controller, a full set of testing and installation tools, and quality-identification video tutorials. The USD 30 sample fee is fully deductible against your first bulk order — effectively making the sample free. Samples ship within 1–3 days of payment.

Samples: 1–3 working days. Cut sheet (pre-cut film): 3–5 working days. Roll film: 5–7 working days. Large mass-production orders: 25–35 days depending on quantity and customization. Switchable laminated glass typically requires 15–20 days due to the lamination process. Rush orders can be accommodated on request.

Installation is a dry-stick process (no water): clean and fully dry the glass surface, peel off the release liner, apply the film from top to bottom using a squeegee to push out air bubbles, then connect the two-wire power cable to the transformer. We supply a step-by-step video tutorial, wiring diagrams and an installation tool kit. Remote video support is available for larger projects. Important: never use water or soapy solution during installation — the film is a dry-apply product.

We offer a 5-year global warranty on PDLC smart film and switchable laminated glass, covering manufacturing defects such as natural delamination, adhesive failure and yellowing. Electronic accessories (transformers, controllers) carry a 2-year warranty. Our after-sales team responds within 24 hours, and replacement parts or films are shipped promptly for verified quality issues. The 3-year failure rate is only 0.8%, far below the industry average of 3%.

Yes — that is our core OEM/ODM service. We customize dimensions (film widths up to 1,800 mm standard, 2,100 mm ultra-wide), film color (white, gray, black, custom color), operating voltage (48–65V AC, nominal 60V), control methods (wall switch, RF remote, Wi-Fi app, voice control, dimming, building automation), logo etching and retail packaging.

We accept T/T (bank transfer) and Alibaba Trade Assurance. For orders ≤ USD 2,500: 100% prepayment. For orders > USD 2,500: 30% deposit, 70% balance before shipment. For repeat customers with 2+ orders, L/C at sight may be available. Trade terms: EXW, FOB, CIF/CFR, DDP to your destination.

Film rolls are packed in hard paper tubes with protective film, then in reinforced export cartons; laminated glass is packed in fumigation-free plywood crates with foam protection. We arrange sea freight, air freight and express (DHL/FedEx/UPS) and provide full customs clearance documents (packing list, commercial invoice, certificate of origin, CE/RoHS/FCC certificates and INTERTEK test reports).

We export to 50+ countries and regions across Europe, North America, the Middle East, Southeast Asia and beyond, serving 2,000+ customers. We have completed engineering projects in 20+ countries including the USA, Germany, Singapore, Ecuador and Vietnam. Our team is experienced with CE-related EU import requirements and Middle East SASO-related documentation.

Yes. For bathrooms and outdoor-facing applications we recommend switchable laminated glass, where the PDLC layer is sealed inside the laminated panel for full moisture protection. Self-adhesive film also works on the dry side of interior bathroom glass, but all edges must be properly sealed with neutral-cure silicone sealant (pH 7, zero shrinkage, solvent-free).

Yes. We support neutral packaging, your logo on film edges and packaging (via ITO etching process), user manuals in your language, and blind shipping to your customers. Many of our partners are regional distributors and installation companies building their own brands. We also offer exclusive distributor programs with annual minimum purchase commitments.

Please share: product type (roll film / self-adhesive film / laminated glass), dimensions and quantities, application scenario, intended use (self-use or resale), preferred voltage and control method, destination country/port, and whether you need installation accessories. You will receive a detailed quotation within 24 hours.
