Polythene sheeting is a plastic film made from petroleum (you may also hear it referred to as polyethylene sheeting, poly sheeting, plastic sheeting, plastic film and poly film). It’s an incredibly versatile product used in a wide range of applications.
Polythene is almost completely waterproof, though it will allow oxygen, carbon dioxide and flavourings to pass through it. It can be clear (transparent), translucent or opaque which makes it useful for a variety of functions. Polythene sheeting is usually sold in rolls (though it sometimes comes in boxes of cut sheets) and different additives can be added to vary its functionality

Medium duty polythene sheeting is around 125 microns and is useful for general protection and to cover large items such as furniture. It’s also good as a floor protector when painting and decorating, and for general wrapping when storing or moving items. Gardeners often use it for cloches or ground warming.
Heavy duty sheeting is around 250 microns and used when more robust protection is needed, usually in construction or industrial applications. It’s ideal for use as a damp proof membrane, temporary roof covering or window repair, for sealing off rooms or protecting countertops, and for protection against the weather, as well as for heavy duty wrapping during storage or transit.
