How do I know what thickness I need when looking for bags?

Here is an overview of bag thicknesses and their uses:

  • 1.5 mil = ideal for packaging small screws, parts, clothing, and a wide variety of other items that need protection from dust and dirt
  • 2 mil = standard duty weight
  • 3 mil = offers strength and toughness at significant cost savings; ideal for parts, tools, and a variety of other applications
  • 4 mil = heavy-duty bag for heavier products
  • 6 mil = Super heavyweight bags are the right choice for sharp-edged products, such as metal dies, hardware and plumbing supplies, etc.

The gauge of the material is measured in thousands of an inch, called 'mils.' A bag that is 1.5 mil is 0.0015" thick.
