(a) PVA1 glue coated tag; (b) PVA2 coated tag (two samples); all on Fabric (A). Even though the PVA1 glue dissolves in water, the tag coated with this wet glue performs well. After drying up, the glue and the PVA1 coated tag operate like before washing, with a 1.5 dB decrease in realised gain. The gain of the PVA2 coated tag decreases by 3 dB.
