It’s durable, flexible, and cost-effective, making it a go-to solution for countless applications across dozens of sectors. But with so many different types, thicknesses, and colours available, how do you know which one is right for your project?
Don't sweat it. Whether you're a seasoned contractor or just tackling a DIY home renovation, this guide has you covered. We'll walk you through everything you need to know about polythene, from its various types and uses to how to choose the perfect sheeting for your specific needs. By the end, you'll be a polythene pro, ready to tackle any project with confidence.
Since 1998, Indigo Supplies has been a trusted partner for industrial solutions, and we know our stuff when it comes to polythene. We stock a massive range and can even manufacture to your exact specifications. Let's get started.
What Exactly is Polythene Sheeting?
Polythene sheeting is a type of plastic film made from petroleum. It's manufactured through a process called polymerisation, where ethylene gas is subjected to heat and pressure to form long, repeating chains of molecules. The result is a strong, lightweight, and waterproof material known as polyethylene, or polythene.
This material is then typically extruded into large sheets and rolled up for easy transport and use, creating what is commonly known as a polythene roll. Its properties can be customised by adjusting the manufacturing process, resulting in a wide variety of thicknesses, densities, and special features to suit different jobs.
From protecting surfaces during construction to creating sterile environments in healthcare, the applications are nearly endless. Its flexibility and resistance to moisture make it an indispensable tool in industries like agriculture, packaging, and building.
The Many Faces of Polythene Sheeting
Not all polythene is created equal. The type you choose will depend entirely on the job at hand. Here's a breakdown of the most common varieties and what they're used for.
Based on Duty and Thickness
The thickness of polythene sheeting is measured in gauge (UK) or microns (metric). A higher gauge or micron number means thicker, more durable plastic.
- Light-Duty Polythene: This is the thinnest and most flexible option, typically ranging from 100 to 250 gauge (25-62.5 microns). It’s perfect for tasks where high strength isn't a priority. Think of it as a reliable, temporary shield. Common uses include dust covers for furniture, temporary weather protection, and general polythene for packing lightweight items.
- Medium-Duty Polythene: Offering a balance between flexibility and strength, medium-duty sheeting usually falls between 300 and 700 gauge (75-175 microns). It's a versatile workhorse suitable for a broader range of applications, such as medium-weight packaging, garden cloches, and as a general-purpose groundsheet.
- Heavy-Duty Polythene: When you need serious protection, heavy duty polythene is the answer. Ranging from 800 to 1200 gauge (200-300 microns) and beyond, this sheeting is exceptionally tough and resistant to punctures and tears. It’s the top choice for demanding jobs like industrial floor protection, asbestos removal enclosures, and as a robust damp proof membrane (DPM).
Based on Colour
The colour of polythene isn't just for looks; it often indicates specific properties or intended uses.
- Clear Polythene Sheeting: Transparent sheeting is ideal when you need to see what's underneath. It’s widely used in agriculture for greenhouses and polytunnels because it allows sunlight to pass through while protecting plants. It’s also a popular choice for dust covers and general packaging.
- Black Polythene Sheeting: Opaque and UV-resistant, black polythene is perfect for applications where you need to block out light or conceal contents. It's commonly used to suppress weed growth in gardens, for heavy-duty security wrapping, and as a lightproof barrier in photography darkrooms.
- White Polythene Sheeting: This type reflects light and heat, making it useful for applications where temperature control is important. It's often used for shrink-wrapping boats for winter storage or as a protective cover for sensitive materials that need to be kept cool.
- Coloured Polythene Sheeting: You can also find blue polythene sheeting and other colours used for specific industry coding. For example, blue is often used in food processing environments to ensure any foreign material is easily visible.
Specialised Polythene Sheeting
Some jobs require more than just a standard sheet. Specialised polythene is engineered with added features for specific challenges.
- Fire Retardant Polythene: Safety first! This sheeting is treated with chemicals that make it self-extinguishing if it catches fire. Flame retardant polythene is a legal requirement in many public buildings, shipyards, and construction sites, particularly for creating temporary screens and partitions. Look for products certified to standards like LPS 1207. We stock both orange polythene sheeting and white flame-retardant options.
- Damp Proof Membrane (DPM): This is a specific type of heavy duty polythene designed to prevent moisture from passing through concrete floors. A high-quality DPM is essential for preventing rising damp, which can cause structural damage and health issues.
- Visqueen Polythene: Visqueen is a well-known brand name that has become almost synonymous with high-quality polythene sheeting, especially damp proof membranes. It’s a trusted choice for builders and contractors who need reliable performance.
Top Applications for Polythene Sheeting
The versatility of polythene sheeting means it pops up in a surprising number of places. Here are some of its most common and crucial roles.
Construction and Building
The construction industry would practically grind to a halt without polythene. It’s the ultimate polythene for builders.
- Surface Protection: Polythene for floor protection is a classic use. During painting, plastering, or any messy job, spreading a polythene roll across floors and furniture saves hours of clean-up and prevents costly damage. Builders polythene is typically medium to heavy duty to withstand foot traffic and equipment.
- Moisture Barriers: As mentioned, a damp proof membrane is a non-negotiable part of laying a concrete floor. It creates an impermeable barrier against ground moisture.
- Temporary Enclosures: Polythene sheeting is perfect for creating temporary walls, screens, or weather shelters on site, protecting workers and materials from the elements. When safety is paramount, fire retardant polythene is the material of choice.
Packaging and Shipping
From small parcels to massive pallets, polythene is a key player in the logistics world.
- Pallet Wrapping: Stretch wrap, a type of thin, flexible polythene, is used to secure goods to pallets, keeping them stable and protected during transit.
- Product Protection: Polythene for packing is used to wrap individual items, shielding them from dust, dirt, and moisture. Black polythene sheeting is often preferred for wrapping high-value items to keep them out of sight.
- Box Liners: Placing a polythene sheet inside a cardboard box adds a waterproof layer, protecting contents from rain or spills.
Agriculture and Horticulture
Farmers and gardeners rely on polythene to control growing conditions and boost yields.
- Greenhouses and Polytunnels: Clear polythene sheeting is stretched over frames to create controlled environments that extend the growing season and protect plants from harsh weather.
- Weed Control: Laying black polythene sheeting over soil prevents weeds from getting the sunlight they need to grow, reducing the need for herbicides.
- Silage Covers: In farming, heavy-duty black polythene is used to cover silage pits, creating an airtight seal that aids fermentation and preserves animal feed.
How to Choose the Right Polythene for Your Needs
With so many options, selecting the right sheeting can feel overwhelming. Follow these simple steps to make the right choice:
- Identify the Primary Purpose: What is the main job you need the polythene to do? Is it for temporary dust protection (light duty polythene will do) or for a permanent damp proof course (heavy duty polythene DPM is a must)?
- Consider the Environment: Where will the sheeting be used? If it's outdoors, you might need a UV-stabilised sheet to prevent it from degrading in the sun. If it's in a public space or on a high-risk site, flame retardant polythene might be required by law.
- Determine the Required Durability: How much wear and tear will the sheeting face? For protecting a carpet during a weekend paint job, medium-duty is fine. For a long-term construction project with heavy foot traffic, you'll need a heavy-duty option.
- Think About Transparency: Do you need to see through the material? If so, clear polythene sheeting is the obvious choice. If you need to block light or hide contents, go with black.
