Black Polythene Plastic Roll 4m x 100um x 10m – Garden & Landscaping Film

Black Polythene Film for Garden and Landscaping Jobs

This black polythene plastic roll is a handy, all-purpose film for the garden, yard and general jobs around the property. It measures 4 metres wide, 100 microns thick and 10 metres long, giving you a good-sized sheet to cut to suit whatever you are working on. The solid black film blocks light and sheds water, which makes it a practical pick for weed control, ground covering, moisture barriers and protecting surfaces and materials.

A Handy 4m x 10m Roll at 100 Micron

At 4 metres wide, the roll covers a lot of ground in a single lay, and the 10 metre length is easy to roll out, cut and manage on site. The 100 micron (0.1mm) gauge is a light-to-medium film, strong enough for general covering, lining and garden use while staying flexible and easy to handle. You simply unroll it, cut the length you need with a knife or scissors, and put it to work.

Blocks Light and Sheds Water

Being solid black, the film blocks sunlight, which is exactly what you want for suppressing weeds and warming or covering soil. It is also a good moisture barrier, so it helps keep dampness in or out depending on the job, and it protects whatever is underneath from rain, dirt and mess. That combination of light-blocking and water resistance is what makes black poly so useful across so many tasks.

What You Can Use It For

This film suits a wide range of jobs: laying down as a weed barrier under mulch, gravel or garden beds, covering and protecting soil, materials, firewood or equipment, using as a drop sheet for painting and renovation, lining garden and landscaping projects, and general covering around the home, shed and yard. It is one of those rolls that ends up getting used for all sorts once it is on hand.

How to Use

Roll out the film over the area you want to cover and cut it to length with a sharp knife or scissors. For weed control, lay it over the soil and cover it with mulch or gravel, overlapping edges where you need a wider run. As a drop sheet or cover, spread it over the surface or materials and weigh or tape down the edges so it does not lift in the wind. Store the remainder rolled up out of direct sun to keep it in good condition.
