AI-Powered supplier vetting
SummaryHaining Huilong Plastic Co., Ltd. is a China-based manufacturer of vacuum bags, storage bags, and multilayer co-extruded film, operating from Zhejiang with 51 employees and a manufacturing plant exceeding 11,000 m². It reports more than 10 production lines, export sales of 71%–90%, exports since 2010, and markets across South America, East Asia, Europe, Australia, and North America. Production lead time is stated as one month in both peak and off-peak seasons. The supplier describes itself as focused on R&D, environmental protection, automation, and product quality, but reports only two R&D engineers, fewer than five quality-control staff, and no supplier-management-system certification. Buyer records associate the company with Costco Korea for vacuum sealing rolls and bags in 2025, although the provided transaction values are not usable for performance assessment.
Supplier typeThe supplier is explicitly identified as a manufacturer and factory, legally organized as a limited company in Zhejiang, China. Its stated commercial activities and product keywords cover packaging products, vacuum bags, and multilayer co-extruded film.
CertificationsThe supplier-management-system certification field is explicitly recorded as "NIL," indicating no certification is reported in the provided information. This is a stated lack rather than merely incomplete documentation.
Production capacityThe supplier reports more than 10 production lines, a manufacturing plant exceeding 11,000 m², and one-month fulfillment times in both peak and off-peak seasons. Its products are manufactured in-house, and these stated resources and lead times provide explicit evidence of production capability.
Client casesThree 2025 records associate HAINING HUILONG PLASTIC CO., LTD. with Costco Korea for Kirkland Signature vacuum sealing rolls and bags, providing a concrete buyer and product reference. The records do not provide order scale, delivery results, quality outcomes, or repeat-purchase evidence, so the case supports customer experience but not its quality level.
