Blue builder's sacks - 20 inches by 30 inches. Specially designed to suit the building, construction and landscaping industry, rubble sacks – or ‘builder’s sacks’ as they are sometimes known are highly tear resistant bags made from strong recycled polythene. Rubble sacks are a clean and efficient way of clearing debris, and safely deposing of waste. This is because they are highly burst resistant and reduce the risk of sharp objects causing harm on site. They can also be used for transporting materials to projects and around sites – such as gravel, sand, stones and concrete. Kite Packaging supply rubble sacks in pack quantities of 100, making them ideal for commercial use in various labouring industries including building, construction, landscaping, tree surgery and interior design. All of our rubble sacks are made from a nominal 125 micron recycled LLDPE (Linear Low Density Polyethylene), and are super-strong so that they can be reused.
