Types of Polybags
Discover the variety of polybags that we can custom make for you.


Extruded polytube is converted on our bag machines into polybags (polyethylene plastic).  The majority of our polybags are made from low density polyethylene (or LDPE).  They can also be made in medium density (MDPE) and high density (HDPE). 

Polybags using low density polyethylene can be designed & supplied for food grade industries through to heavier weight bags for mining & landscaping, with colouring and / or printing added to make them clearly identifiable. Finished polybags can be supplied loose in cartons or perforated on rolls that provide a tear off feature for easy use.

Depending on its end use, the polybag can be manufactured in the following designs & features:

  • Gusseted Bags
  • Perforated Bags On Roll
  • Carton Liners
  • Bottom Seal Plastic Bags
  • Side Seal Plastic Bags
  • Tinted, Opaque or Clear (Natural)
