Blockheaded Bags

  • Perfect for fast moving packing and fulfilment lines
  • Ideal for speed and ease of packing
  • Holes in the header allow bags to be hung for ease of dispensing

  • Punched out handles – Becoming increasingly popular with click & collect, we can manufacture mailing bags with a punched out carrier handle which can also be used as carrier bags.


Lateral Seals & Gusseted Poly Bags
