Correct wrapping gives airtight bales
When wrapping bales it is useful to stretch the plastic film about 70%; draw two parallel lines with a felt pen with 10 cm apart on the coil, when the film is stretched the width between the lines should be 17-18 cm.
Let the film layers overlap each other about 55% to give the splices the extra seal necessary to effectively prevent leakage. It is also important that the adhesion between the film layers is effective and that round bales are stored standing, read more about this here!
