Protective film is a production-line part as much as a product part. ROTADIE die-cuts with peel tabs, matched release force and anti-static handling so your operators peel, place and press in seconds — with no bubble traps at curved edges.
The Problem We Solve
Your challenge
Display and lens surfaces get scratched in assembly, transit and daily use — and a protective film that bubbles, yellows or leaves adhesive residue creates more returns than it saves.
↓ Our solution
ROTADIE solution
Application-matched protective film die-cuts with silicone-PSA (no residue) technology, optimized release force for assembly speed, and tab formats your line can peel one-handed.

Protective Films & Surface Protection
Die-cut protective films for displays, lenses and metal housings — anti-scratch PET, soft TPU, anti-glare and anti-fingerprint surface films, die-cut to assembly-line formats.
Key Features
- Silicone adhesive system: clean removal, zero residue after aging, Hard-coat PET (3H–5H) for scratch protection, TPU and multi-layer films for curved surface coverage, Anti-glare (AG) and anti-fingerprint (AF) surface options, Die-cut with peel tabs and kiss-cut carrier for line efficiency, Optical grades with total transmittance & haze data supplied
Typical Applications
- Smartphone / tablet display protection, Camera lens and sensor window protection, Automotive display protection (with AB film options), Stainless & painted housing surface protection, Retail & medical device screens, In-process scratch protection during assembly

How to Order
① Define the application — describe the device, the function of the part and the environment it works in.
② Send the drawing — DXF / PDF / STEP, or a dimensioned sketch with tolerances marked.
③ Confirm quantities — prototype quantity and estimated annual volume.
④ Review the proposal — we reply with material options, unit price and tooling cost within 24 hours.
⑤ Sample & validate — typical parts sampled in 3–5 working days (quoted per drawing), then mass production after your approval.

FAQ
1. What information do you need to quote my die-cut part?
Three things: (1) a drawing — DXF, PDF or STEP, even a dimensioned sketch works; (2) the material requirement, or simply the application and environment so we can propose; (3) estimated annual quantity. Every drawing is reviewed by an engineer before quoting, and we return a material proposal, unit price and tooling cost within 24 hours.
2. How fast can I get samples?
Sampling lead time depends on part complexity and is quoted together with your quotation. Typical parts are sampled in 3–5 working days after drawing confirmation; parts requiring special material sourcing or multi-layer lamination take longer. The lead time for your specific part is confirmed before you commit — no vague promises.
3. What is your minimum order quantity?
For prototype and validation runs we accept single-run quantities — you do not need to commit to mass production to test our quality. For mass production, MOQ depends on material and part size; small-quantity production runs are supported with per-unit pricing clearly shown.
4. Do I pay for tooling? Is it reusable?
Custom parts require a die tool, quoted as a one-time cost shown separately on the quotation. The tool stays reserved for your part — repeat orders have no tooling charge. For simple shapes we may use etched or laser cutting with lower or zero tooling cost.
5. How do you control quality?
Three stages: incoming material inspection (thickness, adhesive, certs), in-process inspection during die-cutting, and 100% outgoing inspection before packing. Dimension inspection reports and material certificates are supplied with shipment on request.
6. Which material brands do you convert?
We routinely convert 3M, Nitto Denko, tesa, PORON-class urethane foams, Kapton-class PI films and NOMEX-class aramid papers, plus qualified domestic equivalents when cost matters. All material declarations (RoHS / REACH) are supplied with shipment.
7. Can you ship internationally?
Yes. We ship worldwide from Shenzhen by international express (DHL/FedEx/UPS) for samples and small runs, and by air or sea freight for mass production. Export-standard packing with humidity protection is standard.
8. Can you help if I only know the application, not the exact material?
Yes — that is the normal case. Describe the device, the function the part must perform (seal, bond, shield, insulate, protect), the environment, and any constraints (thickness, temperature, approvals). Our engineer proposes 2–3 material options with trade-offs, and sampling validates the choice before you commit.
