What is an advantage of using plastic swine tags over traditional metal tags?

The advantage of using plastic swine tags over traditional metal tags is indeed that they are waterproof and rust-resistant. Plastic tags do not corrode or rust due to moisture or exposure to the elements, which is often a significant issue with metal tags. This durability ensures that plastic tags can withstand harsh conditions, remain legible for longer periods, and continue to serve their purpose effectively without deterioration.

On the other hand, while plastic tags may be visible, it does not necessarily mean they are more visible than metal tags, as visibility can depend on other factors like color and placement. The claim that they can hold more information isn't inherently true, as both plastic and metal tags can have similar data capacities depending on the design. Lastly, plastic swine tags are generally designed to be cost-effective, suggesting they are not necessarily more expensive than metal tags.
