Our Flat Poly Bags are available in a range of materials including 25mu, 50mu, and 100mu clear LDPE and are suitable for a wide range of uses.
Our clear polythene bags are one of our more popular low cost industrial packaging options. They provide protection from dust, dirt, moisture etc, yet leaving the contents visible.
Although we refer to this product as a Flat Poly Bag, other names include, bottom weld bag, end weld bag, flat bag and flat liner, for example.
The thickness of the bags is measured in microns (mu) as standard throughout our site. However, although this is the standard ITP Packaging measurement used, many people also measure in gauge or millimetres (mm/mil) , or quite simply defined as light duty, medium duty or heavy duty.
Measuring by gauge is the more traditional imperial measurement of polythene whereas micron is the new metric standard.
The gauge of polythene can be converted to micron by dividing by 4. And the thickness in millimetres can be calculated by dividing the micron by 1000.
100mu = 400 gauge = 0.10mm
50mu = 200 gauge = 0.05mm
25mu = 100 gauge = 0.025mm
