The thickness of polythene sheeting is expressed in gauge or microns. Gauge was the traditional imperial measurement of polythene thickness, which has now been replaced by micron as the European metric standard. The higher the gauge/microns the thicker the polythene. The gauge of polythene can easily be converted to a micron measurement by dividing it by four. Furthermore, if you want the thickness in millimetres then just divide the gauge by 4000. As an example, 1000 gauge = 250 micron = 0.25mm.


Typical uses for polythene sheeting:

Light duty polythene (86 micron) - ideally protection when painting, spraying or as a dust cover and for light duty general wrapping for storage and transit.

Medium duty polythene (125 micron) - for all round protection and as a covering for furniture and large items. Ideal for protecting floors when painting and decorating. Also used for cloches, ground warming etc, and for medium duty general wrapping for storage and transit.

Heavy duty polythene (250 micron) - Perfect for heavy duty applications such as a damp proof membrane, for mixing cement, temporary roof covering, temporary window repairs, industrial protection, weather protection and for heavier duty wrapping for storage and transit.

Black Polythene will deteriorate at a much slower rate when exposed to ultra violet light (sun light).
