About heavy duty mailing bags

Heavy duty mailing bags are highly favoured by businesses looking to send heavy or sharp items through the post. They are also popular in mailing and dispatch industries, when sending bulky items such as catalogues and heavy pieces of literature.

Heavy duty mailing bags tend to be manufactured from much tougher and durable polythene than standard mailing bags; this makes them more tear-resistant.

Kite’s range of heavy duty mailing bags

We stock six sizes of heavy duty mailing bags, all of which comply with Royal Mail’s PiP guidelines so that you can accurately calculate your mailing costs.

All our heavy duty mailing bags are co-extruded, which means several layers of film are extruded together to create a more durable bag.

Features:

  • Extra Strong - Made from 90 micron (354 gauge) thick, co-extruded polythene
  • Lightweight – Great alternative to postal boxes
  • Opaque – White outer and black inner ensures these bags are 100% opaque, perfect for confidential items
  • Secure – Strong self-adhesive ‘peel and seal’ strip, on a 40mm lip
