Here are some possible interpretations:
* Informal way to refer to large quantities: "Bulk" often implies a large quantity. So "bulk liter" might be a way of saying "a large volume of liters." For example, someone might say, "I bought a bulk liter of orange juice," meaning they bought a large container holding multiple liters.
* Misuse of "bulk" as a descriptor: It's possible that "bulk" is being used incorrectly to describe the container itself, rather than the quantity. For example, someone might refer to a "bulk liter bottle" to describe a bottle specifically designed to hold a large volume of liquid.
* Specific industry term: In some industries, "bulk liter" might have a specific meaning. This is more likely if it's used in a specific context, like a technical document or industry publication.
To understand the meaning of "bulk liter" accurately, you would need more context. For example, what is the conversation about? What is the product being referred to?
