Import 22mm Aluminium Ropp Caps — Buy in wholesale FOB from Supplier in China

Zibo Ruiyue Packaging Materials Co., Ltd. manufactures 22mm aluminium ROPP caps using multiple stamping or one-time forming processes at their facility in Yiyuan County, Zibo City, Shandong Province, China. The 22mm diameter refers to the standard neck finish size widely used in beverage and pharmaceutical glass packaging. The caps feature an easy-opening mechanism combined with anti-counterfeiting properties, and the supplier offers custom text and pattern embossing according to buyer requirements. The aluminium substrate provides corrosion resistance and forms a hermetic seal when crimped onto container threads.

The caps are produced from aluminium alloy stock, typically 8011 or 3105 grade, which offers the ductility required for thread forming and the strength needed for tamper-evident retention. Standard thickness ranges from 0.18mm to 0.24mm depending on application requirements. The liner system is not specified in the source data; buyers should confirm whether the supplier offers PVC-free, PE, or aluminium-foil laminated liners for compatibility with their product fill. Surface treatments include plain mill finish, coloured lacquer, or UV-cured coating for brand differentiation. The multiple-stamping method referenced suggests progressive die forming rather than deep drawing, which affects material grain structure and mechanical properties.

These caps serve distilleries, wineries, pharmaceutical manufacturers, and food processors requiring tamper-evident closure on glass bottles. The 22mm size fits standard ISO 9003 neck finishes common to 375ml to 1-litre spirits bottles. Buyers in the beverage sector typically require colour matching to brand guidelines, sequential numbering for traceability, or holographic elements for premium positioning. Zibo Ruiyue's custom pattern capability supports these needs. The supplier's location in Shandong Province, a major Chinese industrial region, offers access to Qingdao Port for sea freight. Response rate and average response time data are not available; direct enquiry is necessary to confirm minimum order quantities, lead times, and sampling protocols.

Zibo Ruiyue Packaging Materials Co., Ltd. operates from No. 128, Zhenxing Road, Yiyuan County, Zibo City, Shandong Province, China, postal code 256100. The company holds a harbor trust tier. Response rate and average response time are currently recorded as zero in available data, which indicates either a new listing or incomplete engagement metrics rather than active trading history. The supplier describes itself as an experienced manufacturer of aluminium caps, with forming capabilities spanning multiple stamping and one-time forming methods for ROPP closures.

The source description emphasises customisation capacity for text and pattern work, suggesting in-house die engraving or etching facilities. No information is provided about production capacity, workforce size, annual turnover, client roster, or certification status. Buyers should verify ISO 9001 quality management certification, food-contact compliance (EU 10/2011 or FDA 21 CFR), and any specific beverage-industry approvals directly with the company. The supplier's concentration in aluminium caps rather than diversified packaging indicates specialisation, which may benefit technical consistency but should be confirmed through factory audit or third-party verification.
