Mailing & Courier bags are designed for protecting products and delivery of those products. Plastic mailing bags are lightweight, saves money on postage and water resistant.  Mailing bags are mainly made from paper or plastic. Nowadays, most plastic mailing bags are made of Polyolefin's and they are either mono or co-extruded.


  • Economy lightweight postal mailers: Economy range for simple but effective protection - plain and coloured mailers plus the Maillite range with a pre-printed address window. The cheapest way to send literature to your customers and staff and much lighter than paper envelopes.
  • Blue opaque mail-order goods bags: A range of good value strong bags ideal for 'mail order' sales. Ideal for garments and a myriad of online or catalogue products. The bags are an attractive opaque metallic blue and are strong without being too thick and so expensive. A best seller line for eBay and PayPal customers selling their products on-line.
  • Heavy duty postal mailers: Thicker opaque mailers in a strong co-extruded material where you need to be sure that the mailer can withstand some rough handling in transit.
  • Large heavy duty courier sacks: Massively popular range of large and very large courier sacks with double seals. It is tough quality !
  • Metallic high impact silver mailers: 'Premium Quality' metallic silver mailing envelopes - ideal for high impact mailings.
  • Security mailers: Extra thick (360 gauge) white opaque mailers with a Tamper Evident Sealing Strip. The welds have a side skirt as well to give extra security to the package - for that top secret document!
  • Tamper evident mailers: Range of tamper evident bags available in clear as well as opaque for when bag contents need to be identified.
  • Superlight bubble mailers: The lightest protective envelope on the market today ! The stock range comes in white and silver sizes - waterproof too!
  • Featherpost 'jiffy style' padded mailers: The standard paper padded envelope with a self seal strip for closure. This range is bubble lined rather than pulp filled so whilst being padded to protect contents they are also very light.
  • Document enclosed envelopes: Adhesive backed pouches to give your despatch a professional look - adhere directly onto boxes or pallets with an extremely strong tack adhesive.
  • Paper feel plastic envelopes: A plastic envelopes with the feel of paper (but much stronger and waterproof of course).
