Whether you're waterproofing a construction site, protecting surfaces during renovation, or packaging goods for shipment, polythene remains one of the most versatile materials in industrial applications. This comprehensive guide explores everything you need to know about polythene sheeting and related products.
As leading manufacturers, importers, and suppliers of polythene products, Indigo Supplies has been serving UK businesses since 1998. Our extensive range covers everything from basic poly bags to specialist fire retardant polythene solutions.
What is Polythene Sheeting?
Polythene sheeting (also known as polyethylene film) is a thin plastic material made from ethylene polymers. This lightweight yet durable material offers excellent moisture resistance, chemical stability, and cost-effectiveness across numerous applications.
The manufacturing process involves heating and pressurising ethylene to create long polymer chains, which are then formed into sheets of varying thicknesses and properties. Modern polythene manufacturers like Indigo Supplies can produce materials ranging from ultra-thin films to heavy-duty construction-grade sheeting.
Types and Colours of Polythene Sheeting
Standard Colours and Their Applications
Black Polythene
The most popular choice for construction and landscaping applications. Black polythene provides excellent UV protection and is ideal for weed suppression, moisture barriers, and general-purpose covering.
Blue Polythene
Often used for damp proof membrane applications in construction. The distinctive blue colour makes it easy to identify during building inspections and meets specific building regulations.
White Polythene
Excellent for greenhouse applications and situations requiring light reflection. White polythene helps maintain temperature control and prevents overheating in covered areas.
Clear Polythene
Perfect for applications where visibility is important, such as covering stored materials whilst allowing inspection, or creating temporary windbreaks that maintain light transmission.
Orange Polythene
Typically used for specialist applications, particularly in fire retardant formulations that meet specific safety standards.
Specialist Polythene Products
Fire Retardant Polythene
Essential for construction sites and industrial applications where fire safety is paramount. Our flame retardant polythene meets LPS 1207 standards and provides crucial protection in high-risk environments.
Anti-slip Polythene
Specially textured sheeting designed to provide grip underfoot, making it ideal for temporary walkways and safety applications.
Visqueen Sheeting
A premium brand of polythene sheeting known for consistent quality and performance in demanding applications.
Understanding Polythene Thickness and Gauge
Polythene rolls are available in various thicknesses, typically measured in microns or gauge. Here's what you need to know:
Light Duty (50-125 microns)
Suitable for basic covering, dust protection, and temporary applications where strength isn't critical.
Medium Duty (150-250 microns)
Ideal for most general-purpose applications including polythene for packaging, moderate weather protection, and temporary covers.
Heavy Duty (300+ microns)
Essential for construction applications, long-term protection, and situations requiring maximum durability and puncture resistance.
Applications Across Industries
Construction and Building
Damp Proof Membrane (DPM)
One of the most critical applications for polythene sheet in construction. DPM provides essential moisture protection in foundations, floors, and walls, preventing costly damp problems.
Temporary Weather Protection
Construction sites rely on polythene sheeting for scaffolding covers, material protection, and creating temporary weatherproof enclosures.
Surface Protection
Floor Protection
Protecting finished surfaces during construction or renovation work. Combined with fleece backing, polythene provides excellent floor protection without leaving residue.
Carpet Protection
Specialist films designed to protect carpets and soft furnishings during decoration or maintenance work.
Site Protection
Comprehensive protection solutions for building sites, protecting both work areas and surrounding properties.
Packaging and Storage
Poly Bags and Sacks
From light-duty storage bags to heavy-duty rubble sacks, poly bags offer versatile packaging solutions for numerous industries.
Polythene for Packaging
Protecting goods during transit, storage, and handling. Various grades available depending on protection requirements.
Agriculture and Horticulture
Crop Protection
Poly sheeting provides essential protection for crops against weather, pests, and contamination whilst maintaining optimal growing conditions.
Silage Protection
Heavy-duty polythene rolls ensure proper fermentation and protection of animal feed stores.
Choosing the Right Polythene Supplier
Quality Considerations
When selecting a polythene supplier, consider these crucial factors:
Consistency: Reliable thickness and quality across all orders
Certification: Compliance with relevant standards (BS, EN, LPS where applicable)
Technical Support: Expert advice on product selection for specific applications
Stock Availability: Dependable supply chains to avoid project delays

Installation and Handling Best Practices
Proper Storage
Store polythene rolls in dry conditions away from direct sunlight. Rotate stock to ensure older materials are used first, particularly for UV-sensitive applications.
Installation Tips
Overlap Joints: Ensure adequate overlap (minimum 150mm) for weatherproof seals
Fixings: Use appropriate fixings for the substrate - avoid over-tensioning which can cause splits
Sharp Edges: Protect polythene from sharp objects during installation and use
Joining Methods
For permanent installations, use specialist joining techniques:
- Heat welding for critical waterproof seals
- Double-sided adhesive tapes for temporary joints
- Mechanical fixings with appropriate sealing washers
Environmental Considerations
Sustainability in Polythene Production
Modern polythene manufacturers increasingly focus on sustainable practices:
Recycled Content: Many products now incorporate recycled materials without compromising performance
Recyclability: Most polythene products can be recycled through appropriate waste streams
Reduced Thickness: Advanced manufacturing allows thinner films with equivalent performance, reducing material usage
Proper Disposal
After use, polythene sheeting should be disposed of responsibly through recognised recycling programmes or appropriate waste management facilities.
