Woven aluminium foil price

When sourcing woven aluminium foil, you must prioritize the gram weight (GSM) and tensile strength. High-quality radiant barriers typically range from 100g/m² to 160g/m². Ensure the product uses high-purity aluminium foil (99%+) or metalized PET film laminated to a heavy-duty polyethylene (PE) woven fabric. The reflectivity should be at least 95-97%, and the emissivity should be as low as 0.03 to 0.05 to ensure maximum thermal insulation efficiency.

For construction applications, the product must meet ASTM E84 or BS 476 standards for Fire Retardancy (Class A/Class 1). If the foil is used for food-grade packaging or insulation, verify FDA or EC 1935/2004 compliance. Additionally, ensure the supplier provides ISO 9001 certification for manufacturing consistency and RoHS/REACH reports to confirm the absence of hazardous substances in the adhesive layers.

The lamination technology is critical; look for extrusion lamination rather than simple glue bonding to prevent delamination in high-humidity environments. Double-sided foil structures offer superior thermal resistance compared to single-sided versions. For roofing, ensure the material is perforated if breathability is required to prevent moisture buildup, or non-perforated if it must act as a total vapor barrier.

Pricing is primarily driven by the thickness of the aluminium layer (measured in microns) and the density of the woven scrim (e.g., 8x8 or 10x10 mesh). Fluctuations in global aluminium ingot prices directly impact the cost. Buyers can achieve 10-20% cost savings by ordering in Full Container Loads (FCL) and opting for standard roll widths (e.g., 1.2m or 1.35m) to minimize manufacturing waste.

Request a pre-shipment inspection (PSI) and specifically ask for a peel strength test to ensure the foil does not separate from the woven base. Utilize Made-in-China.com's Secured Trading services to hold payment in escrow until the quality is verified. Always request a production sample before the mass run to serve as a 'Golden Sample' for legal reference.

Focus on the net weight per roll rather than just the price per square meter, as some suppliers may reduce the PE density to lower costs. Negotiate based on long-term volume forecasts to secure 'VIP' pricing. Ask for customized labeling and packaging (e.g., shrink wrapping with your brand) to be included in the FOB price to increase your retail margin.

Woven aluminium foil is sensitive to oxidation and physical edge damage. Insist on heavy-duty cardboard core tubes to prevent crushing and waterproof plastic film wrapping for all pallets. Ensure the container is checked for moisture levels before loading to prevent 'white rust' (oxidation) during long sea voyages. For shipping to the US or EU, clarify the HS Code (typically 7607.20) to accurately calculate import duties.
