You want to enjoy years of a pond. That is why it is important that you choose a sustainable material. This article presents you about the most important advantages and disadvantages of polyethylene pond liner. Polyethylene film is nowadays also used for ponds. But especially the HDPE (high density polyethylene) variant and especially in Koi ponds. HDPE is not easy to process because it is quite stiff and needs to be welded with special tools.
The benefits of Polythene or full polyethylene pondliners are many. They are, first pond foil made of polythene is very cheap compared to foil made of other materials. Two, this agricultural film is available in different thicknesses: choose a minimum thickness of 0.5 mm, 1 mm is better and 2 mm is even stronger. Three, this foil can be supplied up to a width of 8 meters. Four, a special version of polythene film is reinforced polythene. This consists of two layers of polythene with polyester in between, making the film much stronger.
Meanwhile, the cons of polyethylene pond liner include: One, this pond liner has a short life span. Two, polythene is not very UV-resistant, so the quality deteriorates quickly: the plasticizers evaporate with brittle foil as a result. Three, it is also difficult to place since you have to put the foil in the right shape before you put water in the pond. Which guarantees numerous creases and creases. Four, polythene does not stretch well, so you can damage it relatively easily. Five, you can’t glue it, you can weld it.
