AI-Powered supplier vetting

SummaryQingyuan is a plastic and paper packaging manufacturer with eight production lines, a 10,458 m² plant, stated annual capacities of 1,000 tons for PE packaging bags and 750 tons each for vacuum and frozen food bags. It holds ISO 9001:2015 certification and reports documented finished-product inspection, quality assurance, complaint handling, and corrective-action procedures. The supplier offers OEM, ODM, 3D design, sampling, and multiple customization formats. Its R&D profile is mixed: five years of total R&D engineer experience and broad design services are reported, but no new product was developed in the past year and no SDK is available. Export experience spans 12 years, with exports representing 21%–30% of sales, although overseas service coverage is listed as zero. Financial credibility cannot be fully assessed from the provided information because only a reporting year and registered capital are shown; monetary figures are omitted here.

Supplier typeThe supplier is identified as a manufacturer and seller of plastic products, packaging materials, paper products, and biobased materials, with eight production lines and a 10,458 m² manufacturing plant. This supports classification as a packaging manufacturer rather than only a trading company.

CertificationsThe supplier reports an ISO 9001:2015 certificate along with other certifications, but the specific additional certifications are not identified. The stated ISO 9001:2015 certification is explicit evidence of a quality-management certification.

After-Sales capabilityThe supplier reports clear procedures and followed records for customer complaints and corrective and preventive actions, indicating a documented service-response process. However, the overseas-service-country field is listed as zero, so the breadth of international after-sales coverage is unclear.

Production capacityThe supplier reports eight production lines, named film-blowing, printing, composite, cutting, bag-making, and testing equipment, plus annual capacities of 1,000 tons for PE packaging bags and 750 tons each for vacuum and frozen food bags. A defined plant area and production equipment further support established manufacturing capability.

Customization capabilityQingyuan explicitly offers customization from samples and designs, full, minor, and flexible customization, together with 3D design, OEM, ODM, prototyping, and sampling services. The evidence directly supports broad packaging customization capability.
