Import Double Side Aluminum Foil For Flexiblle Duct — Buy in Bulk from Supplier in China

The Double-Sided Aluminum Foil for Flexible Ducts supplied by Hangzhou Dinghe is a laminated product with aluminum foil on both surfaces, typically used as a vapor barrier and thermal reflector in HVAC flexible duct systems. The material thickness ranges from 0.012 mm to 0.025 mm, as confirmed in the source data, with a standard tensile strength of at least 12 N/mm² in the machine direction. This foil is produced without adhesive backing, relying on mechanical bonding to the inner polyester scrim, which is common in industrial-grade ducting applications.

The aluminum used is 8011 or 8079 alloy, standard in HVAC foil applications for its balance of formability and corrosion resistance. The surface finish is mill finish, not embossed, and the foil is supplied in continuous rolls with widths between 300 mm and 1200 mm, matching typical industry tolerances. The inner core is 3-inch cardboard, standard for automated unwinding in duct fabrication lines. No coatings or laminates beyond the base aluminum and scrim are specified, which aligns with cost-effective, high-volume HVAC manufacturing needs.

This product is purchased primarily by HVAC component manufacturers in Southeast Asia, the Middle East, and Eastern Europe for integration into flexible duct assemblies. Buyers typically order in bulk rolls of 500 m to 2000 m per core, with packaging in polyethylene-wrapped cartons. Trade terms are commonly FOB Shanghai or Ningbo, with lead times of 15 to 25 days after deposit. The foil is not certified to ASTM or EN standards unless explicitly requested, and buyers should verify dimensional tolerances and peel strength before bulk procurement.

Hangzhou Dinghe Aluminum Foil And Plastic Products Co., Ltd. is based in Hangzhou, Zhejiang Province, with a manufacturing address at No. 26, Yayuan Village, Linglong Street. The company is classified as an imported supplier with harbor trust tier, indicating it has passed basic platform verification for export compliance.

The supplier specializes in aluminum foil and plastic products for industrial applications, with this listing representing one of its core export items. There is no evidence of in-house R&D, ISO certification, or laboratory testing facilities stated in the listing. Response rate and average response time are not available, suggesting limited buyer communication capacity. Buyers should treat this as a manufacturer of commodity-grade foil without additional quality assurance claims unless verified directly.
