Tie spools
Each tie spool comprises a steel core covered with either biodegradable paper, or a photo-degradable plastic coating, or with PVC.
Two parameters should be considered when selecting ties: strength, so the steel wire comes in several diameters, the purpose of the tie which will determine its degradability.
For example, an exposed vine, requiring no specific forces and for an average bunch weight, our preference would be for a biodegradable paper tie, 0.40 mm diameter. However, for a drip irrigation pipe, we would recommend a spool of PVC tie, 0.40 mm diameter.
