About Zibo Ruiyue Packaging Materials Co., Ltd. - Packaging Items & Containers Supplier in China

The supplier is based in China and lists seven active products. All items are caps used for sealing containers, falling under the Packaging Items & Containers category. The catalogue includes aluminium ROPP caps in diameters of 22 mm, 25 mm and 28 mm, as well as plastic flip‑off and tear‑off caps ranging from 15 mm to 20 mm. Each product is described by its size and type of closure mechanism, such as flip‑off seal caps or tear‑off caps. The listing reflects a focus on small‑diameter closures for bottles and jars.

The product set covers both metal and polymer closures, which are common in food, beverage and chemical packaging. Aluminium ROPP caps are typically supplied in bulk and are compatible with standard threading standards for glass and PET containers. Flip‑off and tear‑off caps are usually molded from polypropylene or PET and are designed for easy removal without tools. The supplier’s catalogue does not specify material grades, but the size range indicates suitability for volume packaging in the 300 ml to 1 L segment. No additional product families beyond caps are listed.

Product Range and Specialties of Zibo Ruiyue Packaging Materials Co., Ltd.

The seven catalogued items consist of three aluminium ROPP caps (22 mm, 25 mm, 28 mm) and four polymer caps: 15 mm and 20 mm flip‑off caps, plus 15 mm and 20 mm tear‑off caps. In the packaging industry, aluminium ROPP caps are graded by wall thickness and inner finish, with common standards such as ISO 1004 for thread geometry. Polymer caps are typically produced in polypropylene (PP) or polyethylene terephthalate (PET) grades that meet FDA food‑contact requirements. Buyers often request specifications such as cap height, thread pitch, and sealing torque for these closure types.

Industry practice shows that aluminium caps are classified under HS Chapter 76 (Articles of base metal) and polymer caps under HS Chapter 39 (Plastics). Typical quality grades include aluminium alloy 1050 for ROPP caps and food‑grade PP with a melt flow index of 12‑18 g/10 min for polymer caps. Standard testing includes torque measurement, leak test at 0.5 bar, and dimensional inspection with tolerances of ±0.1 mm for diameter. These parameters help buyers match caps to their container specifications.

Trade and Export Information - Zibo Ruiyue Packaging Materials Co., Ltd.

China is a major exporter of both metal and plastic packaging closures, supplying markets in Southeast Asia, Europe and North America. Export shipments for caps are usually packed in cardboard cartons, with 500 caps per carton, and loaded in 20‑foot containers at approximately 12 metric tons per container. Common Incoterms used are FOB Shanghai or CIF Rotterdam, depending on the buyer’s logistics preference. Buyers typically require conformity to ISO 9001 quality management systems and, for food‑contact caps, compliance with FDA 21 CFR Part 177 or EU Regulation 1935/2004.

Regulatory checks for caps often involve laboratory analysis for heavy metals in aluminium and migration testing for polymer caps. Importing countries may request a Certificate of Origin and a Material Safety Data Sheet (MSDS) for polymer caps. While the supplier’s catalogue does not list specific certifications, exporters from China frequently obtain CE marking for European markets and SGS inspection reports to satisfy customs requirements. Typical destination industries include beverage bottling, dairy packaging, cosmetics and household chemicals.

Sourcing from Zibo Ruiyue Packaging Materials Co., Ltd. - Buyer Guidance

When sourcing caps from this supplier, buyers should request a product data sheet that lists material composition, wall thickness, thread dimensions and torque values. Samples should be evaluated for fit on the intended container, seal integrity under pressure, and compatibility with any sterilization processes such as pasteurization or autoclave cycles.

Buyers are advised to verify that the caps meet relevant food‑contact standards and to ask for third‑party test reports, for example SGS or Intertek certificates confirming compliance with FDA or EU regulations. Confirm the packaging format (carton count, caps per carton) and the planned shipping term before placing an order. Clarify the minimum order quantity, which for small‑diameter caps often starts at 5,000 pieces per size, and request a lead time estimate, typically 20‑30 working days from order confirmation.

What sizes of caps does Zibo Ruiyue offer?

The catalogue lists caps with nominal diameters of 15 mm, 20 mm, 22 mm, 25 mm and 28 mm, covering both flip‑off, tear‑off and aluminium ROPP styles.

Are the aluminium caps made from a specific alloy?

The supplier does not specify the alloy, but aluminium ROPP caps are commonly produced from alloy 1050, which provides suitable ductility for sealing applications.

Which material is used for the flip‑off and tear‑off caps?

The flip‑off and tear‑off caps are typically molded from polypropylene or PET; buyers should request a material declaration to confirm the exact polymer grade.

What certifications should a buyer request for these caps?

Buyers should ask for ISO 9001 quality‑management certification and food‑contact compliance documents such as FDA 21 CFR Part 177 or EU Regulation 1935/2004, plus any third‑party test reports.

What is the typical packaging format for the caps?

Caps are usually packed in cardboard cartons, with typical quantities of 500 caps per carton, and multiple cartons are loaded onto a 20‑foot container for export.
