Polythene sheeting is a plastic film made from petroleum (you might also hear it referred to as polyethylene sheeting, poly sheeting, plastic sheeting, plastic film and poly film). It’s an incredibly versatile product utilized in a wide range of applications.
Polythene is sort of utterly waterproof, though it should permit oxygen, carbon dioxide and flavourings to pass via it. It can be clear (transparent), translucent or opaque which makes it useful for a variety of functions. Polythene sheeting is often sold in rolls (although it generally is available in boxes of lower sheets) and different additives may be added to differ its functionality, for instance making it fire retardant, UV inhibiting (if it’s to be used outdoor), anti-static (good for use on printed circuit boards), high power and high or low slip. It may also be made from virgin grade, BRC permitted meals grade or recycled polythene, or can even comprise a risky corrosive inhibitor to minimise the formation of rust on the item it is covering.
Polythene Sheeting in Differing Thicknesses
It comes in varied thicknesses, measured in gauge (the traditional imperial measurement) or microns (the European metric normal). The higher the gauge or microns, the thicker the film is. The completely different thicknesses are more suited to totally different applications.
Light duty polythene sheeting could be very thin, around 86 microns, and is usually used as a dust cover or for protection when painting or spraying.
Medium duty polythene sheeting is round a hundred twenty five microns and is beneficial for normal safety and to cover massive objects such as furniture. It’s also good as a ground protector when painting and decorating, and for normal wrapping when storing or moving items. Gardeners typically use it for cloches or ground warming.
Heavy duty sheeting is around 250 microns and used when more strong safety is required, often in development or industrial applications. It’s superb to be used as a damp proof membrane, non permanent roof covering or window repair, for sealing off rooms or protecting counter tops, and for protection in opposition to the weather, as well as for heavy duty wrapping throughout storage or transit.
Colors and Shades
Polythene sheeting could be clear, coloured or tinted and visqueen dpm
comes in quite a lot of colours, useful for color coding. It can also be printed on for branding or info purposes. Black plastic sheeting will hold up much better in opposition to exposure to UV light, and so won’t deteriorate as quickly as other colours in sunlight.
The rolls of sheeting additionally are available in a range of sizes (Abbey Polythene supplies rolls as much as 4 metres vast). It may be centre folded or multi-folded for ease of use and storage and is usually equipped with perforations to make it simpler to tear lengths of sheet from the roll. Punched holes may be added too, as well as micro perforations which will make the film breathable and stop it from misting or fogging up.
