Speaking of colors bleeding...

[Heron]

Ok so most of us know that sometimes colors from one plastic bait can bleed onto another, on physical contact.   Doesn't happen with all brands of plastics, and some brands seem to bleed more than others, while other brands don't bleed at all.   I even have a couple of Zoom brand plastics that used to be Junebug color, but they have bled so much over time that they had lost almost all of their color, and are nearly clear with blue flake.

My curiosity is this.....how exactly does this happen?  What sort of properties does a plastic bait have, that allows it to transfer its color dies so readily?

Idk but one time my dad had a grub and a plastic container in his tackle box and they kind of just... combined.

Probably got hot and melted together.  I get all kinds of fun stuff when I leave stuff in the truck or in the sun.

They are made of plastisol. All dyes are not made equal, some do not combine with the material and leak out of the pourus material. 

 

The melted bait/box is because of a chemical reaction with the plastic and the plastisol.

This. The colorant that is used to dye the plastisol when pouring or injecting the baits comes in non-bleed and regular. The non-bleed will not contaminate other baits. Some types of colorants are harder to work with than others.
