That is the direct answer. Everything below — how the thickness is built, what it defends against, how to compare product lines before you commit a container — supports that number with context you can verify on a data sheet rather than take on faith. Disclosure first: this is Shimao's own site, and Shimao is a paint protection film manufacturer in Hebei, China — a factory, not a trading company. Weigh what follows accordingly, and check everything Shimao says against your own sample testing. ## Why Thickness Still Matters in a Protection Film ![Studio product shot of several large rolls of clear paint protection film standing upright beside](https://www.smwrapfilm.com/wp-content/uploads/2026/11/shimao-626145aa.jpg) Film thickness is the load-bearing spec. A 8.0–9.5 mil TPU construction gives the installer more material to work with during stretching over bumpers and mirror caps, and it gives the panel more sacrificial depth against stone chips, sand blasting on highway driving, and shopping-cart and door-edge contact. A thinner 6.5 mil film is easier to handle on complex curves and costs less per square meter — a legitimate trade-off for daily drivers where the priority is UV and chemical resistance rather than impact depth. The substrate class matters as much as the gauge. TPU sits above TPH and PVC in the market for a reason: it flexes with the panel, self-heals light swirl marks with heat, and resists yellowing longer. Budget TPH stock has its place in short-cycle fleet work, but a distributor building a brand on a five-year customer relationship should anchor the product line on TPU and treat TPH as the entry SKU, not the flagship. On the Shimao floor, the first thing the staff do when a buyer asks about "thickness" is hand them a micrometer and a sample chip. Numbers on a PDF are cheap; a 25 mm peel coupon and a gauge reading in front of you are not. Shimao prefers buyers who measure. ## Protection First — and the Practical Extras That Come With It Stone-chip and abrasion defense is the headline, but a well-built film ships with a stack of secondary benefits that sell the product at the counter: - **Self-healing topcoat.** Light scuffs in the clear layer disappear with sunlight or warm water. This is a topcoat property, not a thickness property — check it on the data sheet separately. - **UV and chemical stability.** Quality TPU constructions resist yellowing, bug etching, bird droppings and road oils. Industry testing commonly quotes 95–99% UV blocking for premium surface films, and solar-control window films reject 40–80% of solar heat gain depending on grade — useful cross-sell figures if you also carry tint. - **Gloss retention and finish options.** Gloss, matte and satin surfaces are available in the same protective class; matte film over glossy paint is one of the fastest-moving looks Shimao sees in export orders. - **Resale value argument.** A car that has lived under film for three years presents cleaner paint at trade-in. Installers use this line because it is true. - **Removability.** Film that peels cleanly without lifting paint protects the next owner too — test this on a painted test panel, not on the customer's hood. One trade-off to say out loud: thicker film is stiffer. On tight compound curves — front bumper corners, mirror backs — an 9.5 mil construction demands more installer skill and more heat work than a 7.5 mil one. Full-vehicle installation commonly takes a two-person crew 1–3 days either way, but scrap rates on thick film run higher for inexperienced hands. The condition under which thick still wins: professional installation and a customer who values maximum impact depth over a faster booth turnaround. ## Choosing a Film Line: What to Compare Before You Order Shimao writes this from the factory floor, and the question buyers ask the staff most at the fair stand is not "how thick is it" — it is "how do I compare your line to the one I already import." Here is the comparison the Shimao team walks them through: | Attribute | Entry TPH film | Mid TPU film | Thick TPU flagship | | --------- | -------------- | ------------ | ------------------ | | Thickness class | ~6.5 mil | 7.5–8.0 mil | 8.5–9.5 mil | | Substrate | TPH/PVC blend | TPU | TPU | | Self-healing topcoat | Limited | Yes | Yes | | Yellowing resistance | Basic | Good | Best in line | | Typical fit | Fleet, short-cycle | Daily drivers | Full-body, show cars | | Written factory warranty | a turnaround commitment | 1–2 years | Up to 2 years typical | Note the warranty row. Written factory warranties in the PPF industry typically run 30 days to 2 years, while marketing materials frequently claim 7–10 years. Those are different documents. Ask any supplier — Shimao included — for the written policy, read the exclusions, and pin the coverage in writing before you print a single brochure. Other checks worth doing before a first order: - **Pin the MOQ per style and colourway in writing.** Volume MOQ flexibility differs by SKU; gloss black and matte finishes move in different minimums at most factories. This is the core of PPF MOQ explained plainly: ask per SKU, not per brand. - **Seal a PP sample and anchor inspection to it.** Every claim — clarity, tack, topcoat behavior — gets judged against the sealed reference, not against memory. - **Check roll width against your cut software.** 1.22 m and 1.52 m are the standard widths; the wrong width silently inflates your scrap percentage. - **Confirm shelf life and storage.** Rolls stored at 18–25 °C commonly carry a 12–24 month shelf life. Order against your sell-through, not against a container discount. - **Run the landed-cost math.** Tariff and freight typically add 8–25% over FOB depending on lane, and established multinational brands command a 30–60% price premium over mid-tier — a wholesale chain of distributor plus installer commonly absorbs 20–40% margin per level. The arithmetic decides which tier of your range each film belongs in. ## More to Explore Across the Shimao Product Range A car paint protection film roll is rarely the only line a distributor needs. The Shimao PPF product line for distributors spans 155 SKUs as of the September 2026 catalogue, and it deliberately overlaps adjacent categories: - **TPU color-change wrap** — Shimao's dominant export line, with gloss, matte and satin finishes in wrap-grade conformability. - **TPH and TPU [clear PPF](https://smwrapfilm.com/clear-paint-protection-film/)** — from entry to the thick flagship class described above. - **Automotive and architectural window film** — solar and ceramic grades, a natural counter sale since ceramic tints commonly block 95–99% of UV. Everything runs on an OEM/ODM basis: your brand, your packaging, your spec. Sample chips from 3 to 30 cm ship within 7 working days, and quotes go out within 3 working days — Shimao commits to both in its standard terms. If you are sourcing factory direct paint protection film as a second supply source, samples cost you a week, not a contract. ## Still Looking for Something? How Shimao Handles Your Data If you did not find the spec you came for, contact Shimao directly — the fastest route to a real answer is a message to the factory, not another product page. And since you are here: a word on how this website itself works, because Shimao thinks buyers deserve the same plain dealing about data as about film gauges. ### Privacy Preference Center The consent banner on this site is not decoration.

Most of the market sits between 6.5 and 9.5 mil. For full-front or full-body work on customer cars, 7.5–9.5 mil TPU is the sensible zone; 6.5 mil suits budget or fleet applications where lower cost matters more than maximum impact depth. ### Is thicker film harder to install? Somewhat, yes. Thick TPU is stiffer on compound curves and rewards an experienced installer with better impact protection. A newer shop may prefer a mid-thickness film to keep scrap rates down, then move up to the thick flagship as their bench skills grow. ### What warranty should I expect from a factory-direct supplier? Judge by the written policy, not the brochure. Written factory warranties in this industry commonly run from 30 days on short-form policies up to 2 years; 7–10 year claims in ads are marketing, not contracts. Get the policy text before you commit. ### What is the minimum order for private-label PPF? MOQ varies by style and colourway, so pin it per SKU in writing before quoting your own customers. Shimao works with volume MOQ flexibility for distributors and brand owners; samples ship within 7 working days so you can test before any commitment. ### How do I compare suppliers before a first container order? Measure a sample chip with your own gauge, run a 25 mm peel test against the data sheet, seal a pre-production sample, and price the landed cost — freight and tariff commonly add 8–25% over FOB. A factory that welcomes those checks is telling you something. Thick film is a specification decision, and specifications deserve evidence.
