AI-Powered supplier vetting

SummaryTianhong New Material Corporation is a packaging-material manufacturer founded in 2008, with a stated manufacturing-plant area of 130,000 m², a 50,000 m² dust-free workshop, and more than 10 production lines. Its capabilities include plastic-film production using imported Italian lines, advanced extrusion and testing systems, and professional printing equipment for PVC, BOPP, PET, and aluminum-foil composite packaging. ISO9001:2015 and ISO14001:2015 certificates are reported. Annual output is described as 10,000 tons in some records, while a designed annual capacity of 20,000 metric tons is also stated. Evidence for after-sales services, financial credibility, innovation programs, customization beyond specified film and printing requirements, and customer cases is incomplete or unknown.

Supplier typeThe supplier is identified as a manufacturer of packaging materials and plastic film, serving packaging and printing, bags, cases and boxes, and agriculture and food applications. Its facilities, production lines, extrusion systems, and printing equipment directly support classification as a packaging-material manufacturer.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certificates, along with other unspecified certifications. These are explicit certifications relevant to quality and environmental management, although the validity scope and certificate details are not provided.

Production capacityThe supplier reports a 130,000 m² manufacturing-plant area, more than 10 production lines, a 50,000 m² dust-free workshop, Italian-imported packaging-film lines, and designed annual capacity of 20,000 metric tons. These explicit facility and equipment details demonstrate substantial production infrastructure, although the records contain differing annual-output descriptions.

Customization capabilityThe supplier states that it produces film to customer-requested specifications, including thickness maintained at 15–60 microns and width of 1,200 mm or less, and provides printing on PVC, BOPP, PET, and aluminum-foil composite packaging according to customer request. This directly supports product and printing customization within the stated parameters.
