Plastic: how high is too high

[Hot Copper Wire]

High ethanol concentration will dissolve plastic, but how high is too high? You know those cheep plastic bottles that cheep vodka come in most namely SKOL? Bottom line vodka and scotch, etc come in plastic bottles. These alcohols are 80 proof. Would these bottles dissolve if they were filled with 100 proof shine? What is the tolerance of these plastic bottles? Does anyone have any experience?

Thanks
