  • Strong which means your envelope won’t tear or rip before it reaches its destination
  • Similar in appearance to a regular envelope - rectangular and flat - and open in the same way, at one end to allow you to place your package contents inside
  • Simple to use, with an adhesive strip running alongside the opening of the bag. Just fill the bag with your postage contents, rip off the covering tape, fold down the flap and your mailing bag is ready to post. Easy peasy!
  • A great way to advertise your business. Get your company logo, design or slogan printed on the outside of the mailing bag and impress your customers as their mail lands on their doormat

Things people say about mailing envelopes

Printed mailing bags need a firm film specification if the finished pack is to grasp its shape and retain the artwork clean through packing and transit.

Mailing bags with handles can make packing lines transport faster when the film is chosen for proper warehouse use. A formed handle gives the operative a clean grip, so bags are easier to lift, sort and load than plain-sided sacks that slip or collapse at the bench.

The advantage only grasps if the film gauge and seal quality are proper, though, since a bright bag that splits in transit creates a far bigger problem than a dull one. A superb selection balances fast identification with secure handling.

Stronger polythene suppliers with a sound self-seal gives better closure security and retains secondary packing simple, which assists dispatch transport faster at the packing bench. The sensible selection is the one that protects the consignment without wasting material or creating avoidable returns.

A proper gauge retains postage down without letting seams split when parcels are stacked or dragged across sorting belts. The smooth film sheds water and dirt well, which assists garments, printed items and flat accessories arrive cleaner than carton alone. Poor sealing, though, fast turns a low-cost mailer into a complaint, particularly if the adhesive strip is weak or the opening is overfilled. A well-chosen poly mailer retains packed units tidy, lowers handling damage, and makes dispatch faster at the bench.

polythene suppliers mailing envelopes suit flat, light items that need protection without the weight and waste of a box. The 506 x 353 mm size gives enough room for documents, folded garments, soft products and similar slim consignments, so packing staff are not forced to crumple the contents only to make them fit. That matters on a busy dispatch bench, where speed and consistency count above clever packaging.

Rigid paperboard mailing envelopes are a better selection when flat items must arrive without creasing or edge damage. The stiff board carries photos, certificates and similar bend-sensitive documents far more securely than a soft paper envelope, so there is no need to add separate stiffeners that take time to insert and add cost to the pack. A superb board grade also grasps its shape through sorting, stacking and courier handling, which assists retain consignments tidy in transit. Made from recycled material, this type of mailer also fits better with basic waste reduction targets. The practical result is a cleaner pack with less components and less risk of damage.

Black Poly Mailers

Black poly mailers are broadly chosen for wholesale shipping because they give a simple, lightweight outer layer that speeds up packing without adding much cost or bulk. The darker film conceals contents better than plain transparent bags, which assists when items are small, mixed or easy to identify through thin packaging. A self-sealing strip also cuts handling time on the packing bench, particularly where dispatch volumes are high and cartons need to transport fast through the lane. White striped versions can make labelling and sorting easier at fulfilment stage, giving a clearer surface for barcodes or notes. That makes them a practical option where speed and discretion both matter.
