Picking the right GSM for your waste bags (without overpaying)

A plain-language guide to bag thickness, from 20 to 120 microns. When to save, when to spend, and the three load-testing questions to ask any supplier.

Thickness — measured in microns or GSM — is the single biggest driver of unit cost in a garbage bag RFP. Get it right and you balance strength against price. Get it wrong in either direction and you either pay for thickness you don't need, or buy a bag that tears in transit and ruins the ROI.

A rough map from microns to use case

  • 20–35 microns — in-room housekeeping bins, dry office waste, small retail carry bags.
  • 35–50 microns — standard municipal wet-waste liners, retail grocery bags, general household.
  • 50–75 microns — hospital biomedical waste, hotel kitchen waste, heavy commercial.
  • 75–120 microns — industrial packaging liners, drum liners, heavy construction debris.
  • 120+ microns — specialised industrial / agricultural / silage applications.

Three load questions to ask every supplier

  1. What weight has this bag been tested to hold, and how? Ask for drop-test data, not just a claim.
  2. What is the failure mode — does it stretch, tear along the seal, or puncture?
  3. What thickness do you recommend for my specific waste stream, and why?

Where customers overpay

The two most common procurement mistakes we see are (1) buying the same thickness across every bin, regardless of the waste stream, and (2) over-specifying thickness "just in case." Both add real rupees per bag that you don't get back. A good supplier will map your bin inventory to three or four thickness SKUs instead of one — and send you a spec sheet to defend the choices.
