|Micro-perforated film offers many advantages when placed over capillary matting - it reduces evaporation, increases matting life, reduces algae growth and improves hygiene. All of this without impairing the capillary action of the matting.
Our films are hot needle perforated, not just pricked like the cheap films that don't work. Comes as a flat sheet on a roll for an easier and neater finish - NOT centre folded. The black polythene has fine perforations 0.5mm, the white polythene has coarse (2mm)
