Anti-static bag

These anti-static bags from Jiangyin Yuanhe Printing & Packaging Co., Ltd. are transparent polythene packaging designed to prevent electrostatic discharge damage to semiconductors, printed circuit boards, and integrated circuits during handling and transit. The construction relies on a dissipative outer layer that slows static buildup, coupled with a conductive or static-dissipative inner surface that safely channels any charge away from enclosed components. Standard thicknesses for such bags typically range from 0.075 mm to 0.15 mm, though buyers should confirm the exact gauge with the supplier.

The material composition usually incorporates low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE) with carbon-black or surfactant-based anti-static additives, creating surface resistivity in the 10^9 to 10^11 ohm/sq range typical for static-dissipative packaging. Unlike metallised static shielding bags, these are single-layer or co-extruded films without Faraday cage protection, making them suitable for components with moderate ESD sensitivity rather than highly vulnerable chips. Reusability depends on surface coating integrity; once scratched or contaminated, dissipative properties degrade.

Primary buyers include electronics contract manufacturers, OEM assembly houses, and distributors handling memory modules, sensors, and passive components. The bags accommodate manual or automated loading, with heat-sealable or self-adhesive closure options common in the trade. For import from Jiangsu Province, buyers typically negotiate FOB Shanghai or Ningbo terms, though the supplier has not published confirmed Incoterms, MOQ, or lead time figures.

Jiangyin Yuanhe Printing & Packaging Co., Ltd. operates from No.11 Kaiquan Road in Jin'nan Industrial Park, Jiangyin City, Jiangsu Province, postal code 214405. The company's location places it within the Yangtze River Delta manufacturing corridor, a region with dense concentration of plastic film extrusion and flexible packaging converters serving electronics and consumer goods sectors. The supplier carries an imported tier designation and a harbor trust tier, indicating basic marketplace registration without premium verification or buyer review accumulation.

The listing provides no disclosed response rate, average response hours, factory size, year of establishment, revenue figure, or client references. No certifications, quality management systems, or export licence numbers are stated in the source data. Buyers should conduct direct due diligence on the supplier's ISO 9001 status, any ESD packaging-specific certifications (ANSI/ESD S20.20, IEC 61340-5-1), and their in-house testing capability for surface resistivity and triboelectric charge generation before committing to volume orders.
