Aluminium mylar tape

When sourcing Aluminium Mylar Tape (AL/PET), you must prioritize the Aluminium Foil Thickness (typically 6μm to 50μm) and Polyester Film Thickness (typically 12μm to 50μm). For high-frequency signal cables, ensure the Total Thickness is consistent to prevent impedance mismatch. Additionally, verify the Tensile Strength (≥ 60 MPa) and Elongation at Break (≥ 15%) to ensure the tape does not snap during high-speed cable wrapping processes.

For cross-border procurement, the product must comply with RoHS 2.0 and REACH standards to ensure it is free from hazardous substances like lead and cadmium, which is critical for electronics exported to the EU and US. If the tape is used in power cables, check for UL Certification or IEC 60754-1/2 (halogen-free) compliance to meet fire safety and toxicity regulations.

The primary function is electromagnetic interference (EMI) shielding. You should request the Shielding Effectiveness (SE) data, usually measured in dB. For high-end applications, look for Double-Sided Aluminium Mylar Tape to provide 100% coverage. Also, confirm the Bonding Strength between the foil and the film; a low-quality adhesive can lead to delamination, which compromises the cable's electrical properties over time.

Selection depends on the end-use: Single-sided tape is standard for general communication cables and computer wires. Double-sided tape is preferred for high-interference environments like data centers. Conductive Aluminium Mylar Tape (with conductive adhesive) is used when electrical grounding through the tape surface is required. For heat-sensitive environments, ensure the tape has a high Heat Resistance rating to withstand the extrusion temperature of the outer jacket.

Always request a Pre-Shipment Inspection (PSI). For Aluminium Mylar Tape, the most common risks are oxidation of the aluminium layer and uneven slitting edges. Ensure the supplier uses vacuum packaging with desiccant to prevent moisture ingress during sea freight. On Made-in-China.com, prioritize 'Audited Suppliers' who can provide third-party verification reports from SGS or Intertek.

Since Aluminium Mylar Tape is a commodity-linked product, prices fluctuate with LME (London Metal Exchange) aluminium prices. Negotiate a formula-based pricing model for long-term contracts. For MOQs, if your volume is low, suggest a standard width (e.g., 500mm or 1000mm) jumbo roll purchase, as customized slitting widths often trigger higher MOQ requirements.

Aluminium Mylar Tape is heavy and susceptible to pressure deformation. Instruct the supplier to use suspended packaging (core-supported) within reinforced wooden crates to prevent the rolls from flattening under their own weight. For shipping to specific regions, clarify the Incoterms (FOB vs CIF); given the weight-to-value ratio, Sea Freight is usually the most economical, but ensure the containers are kept away from heat sources to prevent adhesive degradation.

Utilize Escrow-based payment services or Letters of Credit (L/C) for large industrial orders. Avoid direct wire transfers to private accounts. When sourcing via Made-in-China.com, use their Secured Trading Service to ensure that payment is only released to the supplier after you have confirmed the receipt and quality of the goods.
