Import 305x405mm Peel And Seal Envelope 100g — Buy in Bulk from Supplier in China

This peel-and-seal envelope measures 305 x 405 mm and is constructed from 100 gsm paper, a medium weight suitable for documents, photographs, and light flat items that require rigid protection without excessive bulk. The closure system uses a peelable strip with a pressure-sensitive adhesive layer, eliminating the need for moisture-activated gumming or additional tape. The item number AF-2054 identifies this specific size and format within the supplier's range. The listing indicates a unit price of USD 0.067, though this figure should be confirmed as current, and does not specify whether this is EXW Yiwu, FOB Ningbo, or another Incoterm.

The 100 gsm basis weight is standard for medium-duty mailing envelopes, offering a caliper typically in the range of 0.10-0.12 mm for uncoated woodfree paper, though the exact paper type, whether kraft, white wove, or colored stock, is not stated in the source data. Peel-and-seal adhesives are typically hot-melt synthetic rubber or acrylic emulsion formulations, with a shelf life of 1-3 years before the adhesive strip may begin to lose tack; the specific adhesive type and storage conditions are not detailed. The envelope format at 305 x 405 mm corresponds to a common oversized flat size, accommodating A4 documents with padding or A3 documents folded once, and is frequently used in e-commerce fulfilment, legal document dispatch, and photographic print mailing.

Primary buyers include e-commerce fulfilment centres, legal stationery suppliers, photographic laboratories, and corporate mailrooms that process high volumes of flat items. The minimum order quantity is 5 cartons, with inner packaging of 50 pieces per bag and 1000 pieces per carton, implying 20 bags per carton. B2B purchasers should confirm with Yiwu Joinus Stationery whether the 100 gsm paper is recycled or virgin fibre, whether FSC chain-of-custody certification is available, and whether custom printing in single or full colour is offered, as these factors determine suitability for branded communications and sustainability requirements.

Yiwu Joinus Stationery Co., Ltd. is located at 423# Suxi Road, Xufeng Cun, Suxi, Yiwu, 322000, Zhejiang Province, China. Yiwu is one of the world's largest small-commodity wholesale markets, with extensive export logistics infrastructure including the Yiwu International Trade City and direct rail freight to European destinations. The supplier holds a harbor trust tier, indicating baseline marketplace verification, but its response rate is recorded as 0.00% with zero average response hours, which suggests either a newly registered account or inactive inquiry management. Buyers should initiate contact to assess responsiveness before relying on this supplier for time-sensitive orders.

The company profile does not state establishment year, registered capital, number of employees, annual turnover, factory ownership status, or existing client base. There is no mention of quality management certification such as ISO 9001, environmental certification, or social compliance audit status. The listing focuses on a single envelope SKU with basic size, weight, and packaging data, without indicating whether Yiwu Joinus operates its own paper converting facility or sources from third-party manufacturers. Importers should request a company profile, factory audit capability, and sample evaluation before committing to the 5-carton minimum order, particularly if customisation or consistent colour matching is required.
