Our film thickness guide
Our polythene thickness guide aims to help new comes choose the correct polythene and plastic bags. It offers guidance on how we measure the thickness of the plastic. Polythene is produced in different sizes and strengths to suit different applications. The following polythene film thickness guide aims to provide advice on film material and thickness so that you can make an informed purchase.
The following table lists common film material and gauge and the properties of each in terms of strength and clarity.
One micron is about 4 gauge. One micron is equal to one thousandth of a millimeter (0.001mm).
A 20 microns or 80 gauge bag is able to hold items up to about 1.5kg. Making it really only good for light duty protection from dust and moisture.
Heavy duty polythene bags are 125 microns or 500 gauge 125 microns is 0.125mm thick. 125 microns is extremely tough and highly resistant to tears and punctures. In terms of capacity 125 microns bags are able to hold up to about 20kg.
