This A3 envelope is constructed from 100G paper, offering a sturdy build for secure document transit. The adhesive seal ensures contents remain protected during handling and shipping, while the A3 dimensions accommodate larger formats such as folded A2 sheets, brochures or multi-page documents without bending. The recyclable material aligns with standard eco-friendly office practices for packaging.
The 100G basis weight is typical for heavy-duty mailers, balancing rigidity with foldability for insertion into larger mail slots. Industry-standard A3 dimensions measure 297 mm x 420 mm, with a typical tolerance of ±2 mm for cut edges. The surface finish is usually smooth and uncoated, suitable for both handwritten and printed addressing, and compatible with most office printers for custom branding.
These envelopes are widely used by corporate offices for contracts, legal firms for case files and educational institutions for certificates. Bulk buyers often pair them with FOB or CIF shipping terms, confirmed at order stage. The supplier’s location in Yiwu, Zhejiang, provides access to China’s stationery manufacturing hub, where paper grades and adhesive quality are consistently monitored for export compliance.

Before ordering, verify the exact paper weight and adhesive type, as these directly impact durability and suitability for your documents. Request a physical sample to test the envelope’s resistance to bending, tearing and moisture, especially if shipping to humid climates.
Confirm the Incoterms (FOB or CIF) and the port of loading, typically Ningbo or Shanghai for Yiwu-based suppliers. Clarify payment terms, such as TT (telegraphic transfer) or LC (letter of credit), and whether the supplier offers flexible MOQs for trial orders. Lead times can vary; standard production for bulk orders is 15-20 days after deposit.
For quality checks, inspect a pre-shipment sample for consistent dimensions, seal integrity and print compatibility. Request a certificate of conformity (COC) if required for customs clearance in your country. Document the packaging specifications to ensure compatibility with your warehouse or distribution center’s handling equipment.
