## Long description

zenwire Shipping Poly Mailers B4 260×360 mm, pack of 50, are lightweight plastic envelopes designed for secure transit of documents, clothing and small goods. These B4-size poly mailers measure 260 × 360 mm and provide a tear-resistant, moisture-resistant outer layer that shields contents from light rain and handling abrasion. The self-sealing adhesive strip speeds up packing and ensures a flat, compact parcel ideal for postal delivery and courier services.
Advantages
The mailers combine low weight with durable polyethylene construction to reduce postage costs while maintaining protection. Their water-resistant surface prevents moisture ingress and protects paper items and textiles. The self-adhesive closure eliminates the need for tape, and the flexible material conforms to irregularly shaped contents to minimize bulk. A neutral outer appearance suits a range of e-commerce shipments and returns.
Suitable for
 Shipping documents, magazines and printed materials
 Sending folded clothing items such as shirts, scarves or lightweight knitwear
 E‑commerce order fulfillment and customer returns
 Postal and courier shipments where a tear-resistant, moisture-resistant envelope is needed
Key specifications
 Format: B4 (approx. 260 × 360 mm)
 Quantity in pack: 50 pieces
 Material: lightweight polyethylene (plastic) with water‑resistant properties
 Closure: self-sealing adhesive strip
 Properties: tear resistant, flexible, lightweight
How to use
Insert the item into the mailer so it lies flat and smooth any folds to reduce bulk. Peel off the protective strip from the adhesive closure, press the flap firmly along the edge to seal and check the seal for complete contact. For additional protection of fragile items, combine the mailer with internal cushioning such as paper padding or bubble wrap before sealing. Address labels, barcodes and postage marks can be applied directly to the outer surface.
Usage recommendations
For optimal results, use the B4 mailers for lightweight, non-fragile goods and documents. Do not overfill beyond the mailer's capacity; when shipping small items that require extra protection, add internal cushioning. Store unused mailers flat in a cool, dry place away from direct sunlight to preserve adhesive performance and material integrity.
