Uniseel Manufacturer Profile 2026: What Uniseel Is, What It Manufactures, Who It Serves, and Where It Produces

Directa Responsum

Uniseel is the brand of Hangzhou Uniseel Technology Co., Ltd., a manufacturer of internal-thread metal closures — known across the packaging industry as unishell caps — and of the sealing liners that sit inside them. We manufacture tinplate screw caps in the GPI 400 neck-finish family from 38 mm to 89 mm (38/400, 45/400, 53/400, 58/400, 70/400 and 89/400), in silver, gold and custom Pantone-matched finishes, fitted with induction heat seal (IHS), pressure-sensitive (PS), PE foam or paper liners. Our caps and liners are specified by pharmaceutical, nutraceutical, cosmetic and food brands in Europe, the United Kingdom and the Americas. Manufacturing takes place in Lin'an District, Hangzhou, Zhejiang Province, China, at a rated capacity of 250,000 pieces per day.

Omnis campus infra scriptus est ut factum quod per documentum, numerum registrationis aut locum physicum comprobare potest.

Quae generis est societas Uniseel?

Uniseel est fabricator, non intermedium mercatorium. Haec distinctio commercialiter importat: omnis clausura a nobis quotata producitur in nostris propriis machinis stampilandi, filetandi et curvandi, sub uno systemate qualitatis, in una sede. Nomen commerciale Uniseel in parte exportationis negotii ponitur et ab entitate fabricandi Hangzhou Lin'an Shengxiang Technology Co., Ltd. suffultur, quae componentes metallicos praecisos pro confectionibus iam ex annis 1990 fabricat.

Hoc structura unum effectum practicum ad emptores habet: entitas quae contractum tuum signat, entitas quae certificatum ISO 9001 tenet, et entitas cuius machinae ordinem tuum exequuntur, eodem sunt gruppo — itaque specificatio ad statum quotandi consensu data non iterum interpretatur ab altera parte ad statum productionis.

Ubi Uniseel fabricat?

Omnes productiones fiunt in loco No. 57, Hongqiao, Gaohong, Districtus Lin'an, Habu, Provincia Chekiang, Sinae 311307. Fabrika dotata est lineis intelligenribus ad formandam laminam, machinis internis ad filettandum fabricatis in domo, et unitatibus automaticis ad volvendum, quae omnes sub nostris patentibus elaboratae sunt; fabrika operatur ad capacitem nominalem 250 000 partium per diem. Quoniam instrumenta designantur et curantur in domo, mutationes diametri vel filetti, quae postulantur in tempore exemplorum, sine interventu externi officini instrumentorum fieri possunt.

Quid Uniseel fabricat?

Familia productorum est clausura metallica GPI 400 interna filettata — in usu industriali, capsula unishell. Sex diametri corporis in productione seriali sunt, quae singulae ad certum vas et mercatum aptantur.

Sealing liners are supplied as an integrated part of the closure, not as an afterthought. Four liner technologies are available depending on the barrier the product requires: induction heat seal (IHS) aluminium foil for hermetic tamper-evident sealing; pressure-sensitive (PS) foam liners for machine-free resealable protection; PE foam liners; and paper liners used to adjust stack height on aluminium bottle applications. Liner selection is decided together with the customer, because the correct answer depends on the filling line, the container material and the shelf-life target — not on the cap alone.

Who does Uniseel serve?

Uniseel supplies packaging buyers rather than consumers. The four demand groups we manufacture for are:

• Pharmaceutical and healthcare packaging — glass and plastic bottles requiring documented food-contact and chemical-safety evidence, tamper evidence and batch consistency.
• Nutraceutical and supplement brands — PET jars and glass bottles where moisture and oxygen barrier performance directly affect shelf life.
• Cosmetic and skincare packaging — jars where a Pantone-matched finish and an embossed logo carry brand identity as well as function.
• Food and beverage, including honey and syrup — applications requiring anti-stick coatings and closures able to tolerate viscous, sticky fills.

Which certifications and test reports does Uniseel hold?

Compliance claims are only useful when they can be traced to a document. The table below maps each claim to the standard it is measured against and the document that proves it.

What patents does Uniseel hold?

Uniseel habet 21 patentia Sina concessa. Non sunt hae formales petitiones: quaelibet ad machinam vel gradum processus pertinet, qui accuratitudinem dimensionalem clausurae finitae determinat. Portfolium complectitur cunei praecisionis pro stamping, apparatus pro machinatione internorum filetorum, dispositiva pro praecurvatione, lineas intelligentes pro stamping et curvatione, apparatus sigillantes multi-stationales, et interfaces automaticas ad capsulas applicandas altissimae velocitatis. Exemplaria patentia concessa includunt ZL 2023 2 3287198.X (cuneus intelligens pro stamping), ZL 2023 2 3012889.9 (contineris duplex hermeticus resistentis radiationi), CN221434750U (technologia praecurvationis), CN224026207U et CN224026254U (lineae productivae intelligentes pro curvatione et stamping), CN120438729A (apparatus intelligens pro internis filetis), CN221112162U (apparatus sigillans multi-stationales), CN221109686U (apparatus multifunctionalis pro elaboratione capsularum), et CN203780993U (capsula metallica cum fileto interno integrato).

The measurable output of this tooling is a controlled dimensional tolerance of ±0.1 mm, which is the parameter that determines whether a closure seats and seals consistently on a high-speed capping line.

Where does Uniseel export?

Current export activity covers the European Union — including France, Germany, Poland, Spain, the Netherlands, Hungary and Slovenia — the United Kingdom, and the Americas, including the United States and Chile. Because the regulatory obligations differ by destination, shipments are prepared with the destination-specific documentation in place: HS classification as tinplate screw caps under 8309 90 90 00 for the European Union, food-contact declarations where required, and evidence of packaging EPR registration for both Germany and France.

How can a buyer verify Uniseel?

Profilus fabricantis tantum valet quantum per se verificari potest. Quinque gradus verificandi ad omnes emptores patent, nihil a nobis petendo:

• 1. Adressam conferre. Adressa in citatione, in factura et in certificato ISO 9001 est: No. 57, Hongqiao, Gaohong, Districus Lin'an, Hangzhou, Zhejiang, Sina 311307. Si suppeditator ab alia adressa citat quam in certificato qualitatis nominatur, certificata ad productionem tuam non pertinent.
• 2. Reportum, non affirmationem postulare. Omnis declaratio de conformitate in hac pagina ad numeratum documentum SGS aut TÜV Rheinland refertur. Documentum eius numeri postula et confirmare potes ut modelum producti in eo idem sit quod emere vis.
• 3. Registrationes EPR per se inspicere. Registratio Germanica pro confectionibus in registro LUCID sub numero DE1853254565231 quaeri potest; registratio Gallica sub numero UIN FR535332_01OYDP apud organismum eco Léko habetur. Utraque directe investigari potest.
• 4. Verify the patents. Each patent number listed above can be retrieved from the Chinese patent database and will return the equipment or process it protects.
• 5. Test before you scale. Request a sample lot against your own container, run it on your own capping line, and check application torque and seal integrity before committing to a production order.
