Heavy Duty Polythene Mailing Bags - 250mm x 350mm - Pack Of 1000


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. Our heavy duty mailing bags are manufactured from much tougher and durable polythene than standard mailing bags; this makes them more tear-resistant.


  • Heavy duty mailing bags made from 90 micron polythene
  • Almost double the thickness of regular polythene mailing bags
  • Made from co-extruded material, using several layers of film for tear-resistance - perfect for heavy or sharp items
  • Off-white outer and black inner so bags are 100% opaque
  • Peel and seal self-adhesive strip for fast and easy closure
