Our best-selling plastic mail bag
Blue mailing bags are designed to ship clothing, textiles and soft goods in an opaque blue polythene outer and are great choice to stand out amongst the more common grey finish. The 45 to 60 micron film is lightweight and tear-proof, keeping postage down while resisting splits in handling. A self-seal adhesive strip closes each bag without tape and acts as a tamper-evident seal, showing clear evidence if the bag is opened. These blue mailer bags are available in multiple sizes, from 245 x 345mm up to 483 x 737mm, covering brochures and small garments through to bulkier or oversized courier items. The opaque surface takes labels cleanly.
Sold in packs of 250, 500 or 1000 depending on size, priced per pack.
Where do blue mailing bags work best?
Blue mailing bags suit high-volume despatch of soft goods and textiles through post and courier networks, with a lightweight blue outer material and fast self-seal.
- Mail order clothing and textiles, where a flexible bag keeps postage weight down.
- Online retail fulfilment, where the self-seal strip speeds up repeat packing runs.
- Brochures and flat items, where smaller sizes give an opaque outer for printed material.
- Larger courier consignments, where sizes up to 483 x 737mm take bulkier or oversized soft goods.
Not for
- Fragile products without protection. Add cushioning inside or use cardboard boxes for crush resistance.
- Sharp-edged items that can pierce polythene. Box or pad them before bagging.
- Paper-based packing policies. Choose Kraft paper mailing bags where paper packaging is required.
