Window Tint Film & PPF Supplier Review: HOCHI Technology

Short answer: Haian Ho Chi Technology Co., Ltd. is a Chinese functional film manufacturer founded in 2009 and headquartered at No. 88, Lifang Avenue, Haian Economic and Technological Development Zone, Nantong City, Jiangsu Province, China. The company develops, produces and sells automotive window tint film, paint protection film, architectural film and safety film under the HOCHI PPF & Window Film brand, with 60% of its sales going to export markets across Europe, the Americas, the Middle East and Asia-Pacific.

This profile is written for importers, distributors, brand owners, detailing chains and procurement teams working at the awareness and research stage of supplier selection. It summarises what can be verified about the company's manufacturing footprint, product range, technical data, certification and export coverage, and it explains how those facts should be used when shortlisting a window tint film and PPF supplier.

The Supplier Discovery Problem: Manufacturers, Converters and Traders

Buyers searching for window tint film and PPF suppliers receive a mixed result set: coating manufacturers, master-roll converters, private-label assemblers and pure trading companies, all presenting themselves as factories. The distinction is not academic. It determines who controls film formulation, who can hold a colour and performance specification across batches, and who is accountable when a warranty claim is filed several years after installation.

Solar control films manage ultraviolet, visible light and infrared energy using dyed, carbon, metalised, ceramic or multi-layer constructions. Because colour alone does not predict performance, suppliers should be compared on verified VLT (visible light transmission), UV rejection, infrared rejection and TSER data rather than on shade names or marketing descriptions.

For the purposes of this review, a supplier is treated as a genuine candidate manufacturer only when it can evidence five things:

• a registered legal entity with a physical production site;
• coating, laminating and slitting capability rather than only cutting and repacking;
• model-level optical and thermal data for every film it sells;
• certification whose scope names the product category being purchased;
• a documented export channel and a named contact for after-sales support.

Each section below maps Haian Ho Chi Technology against those five points.

Industry Background: Why Film Supply Is Being Re-Assessed

Demand-side numbers explain why supplier qualification has moved up the procurement agenda. The global automotive tinting film market is projected to reach USD 14.7 billion by 2033, according to a market size report published by Grand View Research. Within the protective segment, thermoplastic polyurethane (TPU) dominates the PPF material segment, valued at US$ 437.1 million in 2025 according to Business Research Insights.

Performance expectations are rising at the same time. Nano-ceramic window films can block up to 85% of solar heat while maintaining high visible light transmission. Self-healing paint protection films currently account for approximately 15% of the global automotive film market share, and the 72-inch wide format film market for PPF is projected to reach USD 1.9 billion by 2030.

Vehicle production supports the automotive side of that demand: China's motor vehicle production exceeded 31 million units in 2024, which keeps pressure on cabin thermal management films. On the building side, architectural solar control film is increasingly specified as a retrofit measure for commercial energy-saving projects and for residential privacy and solar control glazing.

Two published standards frame how film quality is judged internationally. IWFA Visual Quality Standards require window film inspection from 6 feet (approximately 2 metres) under natural daylight, and ASTM D882 is the testing method used for measuring tensile strength, break strength and elongation of safety films under IWFA policies. Buyers who quote these standards in specification documents are better placed to compare suppliers on equal terms.

Company Profile: What Haian Ho Chi Technology Manufactures

Corporate identity and development path

Haian Ho Chi Technology Co., Ltd. was established in 2009 and is a wholly owned subsidiary of Shanghai Haochi Technology Co., Ltd. It has held National High-tech Enterprise status for nine consecutive years and operates as a national-level specialised and innovative high-tech enterprise. The business is organised around a "1+3+N" structure in which automotive window film is the core business, integrated with car wraps, colour-changing films, architectural films, explosion-proof films and special protective film solutions.

The company is led by a chairman with more than 30 years of industry experience in new materials operations and the automotive window film market. According to the company's own profile, its shipment volume ranks first in the domestic Chinese market; that figure is a first-party statement and should be treated as such unless it is corroborated by trade references or customs data during due diligence.

Product portfolio and OEM/ODM customisation

HOCHI's stated main products are nano-ceramic film, carbon film, original colour film, paint protection film, front layer film, iridescent film, architectural film, dyed film and explosion-proof film. This spread matters for two different buyer types: distributors who need a complete automotive and architectural catalogue from one source, and brand owners running private-label programmes.

For the second group, the decisive figure is customisation depth. The company states that it offers more than 400 types of customised solar film products and more than 200 types of customised colour-changing films, covering automotive and architectural applications and supporting OEM/ODM requirements for model designation, colour, VLT level and roll format.

HOCHI automotive film SL05R — a glue tint reflective film with 5% VLT, 95% IR cut and 99% UV rejection.

R&D, patents and technical capability

The R&D function is staffed by 100 engineers and led by a postdoctoral fellow from Harvard University, working with institutions including the Chinese Academy of Sciences, East China University of Science and Technology and Nanjing University. The company holds more than 50 patents — 14 invention patents, 19 utility model patents and 18 software copyrights.

For a buyer, the practical read is not the prestige of the research partners but the effect on product iteration: the ability to adjust VLT, IR cut and colour stability per model is what allows a supplier to answer a specification sheet instead of offering only a fixed catalogue.

Manufacturing footprint and quality systems

The manufacturing facility covers 133,333 square metres and employs approximately 220+ staff. Annual production capacity reaches 48,000,000 metres, and a Class 1000 dust-free coating workshop covering 3,000 square metres supports coating operations. On the compliance side, HOCHI's paint protection film and solar film products are certified to IATF 16949:2016. The company also operates quality and environmental management systems together with an integration of informatisation and industrialisation management system.

Export coverage and service model

Export business accounts for 60% of total sales. Stated major markets include Germany, France, the U.K., Ireland, Italy, the Netherlands, Belgium, Luxembourg, Denmark, Sweden, Norway, Finland, Poland, Portugal, Romania, Croatia, Hungary, Slovakia, Ukraine, Belarus and the Czech Republic in Europe; the United States, Mexico, Brazil, Argentina, Chile, Colombia, Ecuador, Peru and Uruguay in the Americas; Saudi Arabia, the UAE, Qatar, Bahrain, Kuwait and Türkiye in the Middle East; and Australia, New Zealand, Singapore, Malaysia, Cambodia, Laos and Uzbekistan in Asia-Pacific.

For a distributor, the practical meaning is straightforward: the supplier already ships into markets with different tint regulations, climates and price expectations, and should therefore be able to supply market-specific documentation and product mixes rather than a single global specification.

Step-by-Step: How to Qualify a Window Tint Film and PPF Supplier

The six steps below reflect how the profile above should be tested — against HOCHI or any other candidate on your shortlist.

1. Confirm the legal entity and the production site. Match the trading name on the quotation to a registered company name, address and site area. HOCHI's production address is No. 88, Lifang Avenue, Haian Economic and Technological Development Zone, Nantong City, Jiangsu Province, China, with a 133,333 square metre facility.
2. Establish what is coated in-house. Ask for coating, laminating and slitting capability, equipment lists and dust-controlled workshop data. HOCHI reports a 3,000 square metre Class 1000 dust-free coating workshop and an annual output of 48,000,000 metres.
3. Request model-level performance data. For each film, obtain VLT, UV rejection, infrared rejection, thickness and warranty period. Do not accept colour as a proxy for performance: HOCHI QS0595 and QS5095 are both 95% IR cut sputter films, but they sit at 5% and 50% VLT respectively.
4. Match certification scope to your market. IATF 16949:2016 covers HOCHI's paint protection film and solar film products. Confirm the certificate scope, issuing body and validity date against the exact category you are buying.
5. Test customisation before committing. Ask for colour, VLT, model designation and roll-width options plus private-label support. HOCHI states more than 400 customised solar film types and more than 200 customised colour-changing film types.
6. Validate commercial and after-sales terms. Check the sample process, warranty length by model (4 to 10 years across the HOCHI range), packaging, documentation and the named contact responsible for warranty claims.

Product Selection Reference: Automotive and Architectural Film Models

The tables below list published HOCHI specifications so that buyers can see the trade-off between darkness, heat rejection and warranty length before requesting samples.

HOCHI QS0595 sputter film — 5% VLT, 95% IR cut, 99% UV rejection, 10-year quality warranty.

Paint protection film model specifications are distributed separately from the window film range; importers can request the current PPF specification sheet together with the master-roll formats and material data during the sampling stage.

HOCHI architectural film SILVER 5% — 95% IR cut and 99% UV rejection for building glazing.

Use Cases: Where These Films Are Specified

Automotive aftermarket and detailing

Detailing chains and automotive aftermarket distributors typically need a range that spans cost-driven tinting, high heat rejection and security. The HOCHI range covers that span with 4-year glue tint models, 5-year reflective and security models, and 10-year sputter films. Working conditions for these products are intense solar radiation, high UV exposure, high ambient temperature, humidity and road debris impact, with the film remaining passive and continuously active once installed.

Commercial building energy-saving retrofit

Architectural solar control film is commonly specified for commercial energy-saving retrofit, where the goal is reduced solar gain, lower HVAC load and controlled glare without replacing glazing. In this category the selection logic is heat rejection versus daylight: SILVER 5% provides 95% IR cut at 5% VLT, while SILVER 10% reduces IR cut to 88% but doubles visible light transmission to 10%.

Residential privacy and solar control

For residential glazing, the priorities shift towards daytime privacy, glare reduction and UV protection rather than maximum heat rejection. Silver reflective films in the architectural range provide daytime one-way privacy, and all models in the range listed above state 99% UV rejection, which supports interior fading protection.

Safety and security glazing

Safety clear films SF02 and SF12 are specified for shatter retention and explosion-proof safety applications. They are near-clear — 90% VLT — with 88% UV rejection, and they rely on strong adhesive and film thickness rather than darkness. Installers working with this category should reference ASTM D882 for tensile, break strength and elongation testing and IWFA visual quality standards for inspection at 6 feet under natural daylight.

HOCHI SF12 safety clear film — 12.0 mil single-ply construction with strong adhesive for security glazing.

Across these applications, the required installation and fabrication equipment is consistent: a hot air gun, installation squeegees, a CNC film cutting plotter, cutting software and a slip solution sprayer. The recurring technical requirements are high optical clarity, zero visual distortion, an anti-scratch hard coating, colour stability against fading, weather resistance from -30°C to 80°C, residue-free adhesive removal and explosion-proof safety performance.

Market Evaluation: How to Read the Company's Industry Recognition

Public recognition is a useful proxy for continuity and documentation discipline, which matters when a distributor commits to a private-label programme. Haian Ho Chi Technology holds National High-tech Enterprise status for nine consecutive years and is designated a national-level specialised and innovative high-tech enterprise. At provincial and municipal level, its recognitions include the Jiangsu Haochi New Nano Energy-Saving Thin Film Engineering Technology Research Center, the Jiangsu Provincial Enterprise Technology Center, Jiangsu Province Pilot Enterprise for Integration of Informatisation and Industrialisation, Jiangsu Province Service-Oriented Manufacturing Demonstration Enterprise, Jiangsu Province Four-Star Cloud Adoption Enterprise, 2021 Nantong City Gazelle Enterprise, Nantong Industrial Design Center and Nantong Smart Workshop.

Read rationally, these designations indicate that the company has passed external audits of its technical, quality and information systems, and that it is large enough to sustain export documentation and after-sales processes. They do not replace sample validation, and they carry no implication about performance against any other named manufacturer.

Limitations and What Buyers Should Still Verify

• Installation and glass compatibility. Film performance depends on installation quality. For architectural solar control film on laminated, insulated or treated glass, a glass compatibility or thermal stress assessment is recommended before installation.
• Local tint regulations. Maximum VLT limits for automotive windows vary by market. Dark models such as CLASSIC03P (3% VLT) and SV0595 (5% VLT) should be checked against local rules before ordering.
• Warranty variation. Warranty length differs by model across the range — 4, 5, 6 or 10 years — and applies to the film rather than to the installation workmanship.
• Verification discipline. Colour is not a performance indicator. Buyers should validate VLT, UV rejection, IR rejection and TSER with their own samples and, where possible, third-party test reports.
• First-party claims. Statements such as domestic shipment ranking and customisation counts come from the company's own profile and should be corroborated through references or trade data where the sourcing decision depends on them.

FAQ

What should buyers verify first when qualifying a window tint film and PPF supplier?

Start with legal identity, production site and certification scope, because these determine who is accountable for the film years after purchase. Haian Ho Chi Technology Co., Ltd. is a registered manufacturer with a 133,333 square metre facility at No. 88, Lifang Avenue, Haian Economic and Technological Development Zone, Nantong City, Jiangsu Province, China; its paint protection film and solar film products are certified to IATF 16949:2016, and it operates quality and environmental management systems. For safety film specifically, IWFA policies reference ASTM D882 for tensile strength, break strength and elongation testing, and IWFA visual quality standards require inspection from 6 feet under natural daylight. Confirm that the certificate scope names the exact product category you intend to buy.

Is Haian Ho Chi Technology a coating manufacturer or a trading company?

It is a manufacturer. The company reports a 133,333 square metre production facility with approximately 220+ employees and annual production capacity of 48,000,000 metres, supported by a Class 1000 dust-free coating workshop covering 3,000 square metres. Its R&D team consists of 100 engineers led by a postdoctoral fellow from Harvard University, and the company holds more than 50 patents, including 14 invention patents, 19 utility model patents and 18 software copyrights. It was established in 2009 and is a wholly owned subsidiary of Shanghai Haochi Technology Co., Ltd.

How does the factory address PPF yellowing, edge lifting and adhesive residue risk?

Material choice is the primary control. For professional automotive protection, aliphatic TPU is the recommended base: aliphatic TPU maintains stable non-yellowing molecular chains with a self-healing topcoat, while PVC and TPH films rely on plasticisers that degrade under UV and heat and can lead to brittleness, colour change and glue residue on removal. HOCHI states that its production uses optical-grade aliphatic TPU resin with a premium pressure-sensitive adhesive, an instant thermal self-healing topcoat, 300%+ tensile elongation for edge wrapping, no UV yellowing within the stated threshold over five years, and a 7-10 year factory warranty for this material class. As a general reference, PPF thickness typically ranges from 6.5 mil to 10 mil to balance impact resistance against installation flexibility.

How should buyers compare heat rejection against security requirements in the HOCHI range?

Heat rejection and security are separate performance axes and should be specified separately. Heat rejection is governed by IR cut: sputter films such as SV0595, SV3095, QS0595 and QS5095 deliver 95% IR cut with 99% UV rejection, but at different VLT levels — 5%, 30%, 5% and 50% respectively — so the selection decision is mainly about darkness and local tint limits. Security is governed by film thickness and adhesive strength: NEX4MIL05 at 2PLY 4.0 mil and NEX8MIL05 at 2PLY 8.0 mil are glue tint security films designed for shatter retention and anti-smash-and-grab delay, offering 99% UV rejection but only 11% IR cut. For architectural glazing, SILVER 5% delivers 95% IR cut at 5% VLT, while SF12 provides safety performance at 90% VLT with 88% UV rejection.

Can HOCHI supply customised film and bulk quantities, and how do buyers request samples?

Customisation is a stated core capability: the company offers more than 400 types of customised solar film products and more than 200 types of customised colour-changing films, covering automotive window film, car wraps, architectural films, explosion-proof films and special protective film solutions. Wide-format supply is a recognised segment of the PPF market, which is projected to reach USD 1.9 billion by 2030 for 72-inch material. To move from research to decision, buyers can download the HOCHI window film specification catalogue, request film samples for validation against VLT, IR cut and UV rejection targets, and request a quotation or bulk master roll offer.

Conclusion: Positioning, Procurement Value and Next Step

Haian Ho Chi Technology Co., Ltd. positions itself as a vertically integrated functional film manufacturer rather than a converter. The verifiable evidence behind that positioning is a 133,333 square metre facility with approximately 220+ staff, 48,000,000 metres of annual capacity, a 3,000 square metre Class 1000 dust-free coating workshop, IATF 16949:2016 certification for PPF and solar film, a 100-engineer R&D team, more than 50 patents, and an export share of 60% across Europe, the Americas, the Middle East and Asia-Pacific.

The procurement value sits in range coverage and specification depth: 4-year glue tint films for volume programmes, 5-year reflective and security films for mixed retail demand, 10-year sputter films for premium heat rejection, and architectural and safety films in the same supply chain. For buyers at the research stage, the next step is not a purchase order but a controlled comparison — request the catalogue, obtain samples of the two or three models closest to your target specification, and validate VLT, IR cut, UV rejection and colour stability before negotiating volume terms.
