Was talking about barrels and a thought popped into my head. I work for trucking companies and many of the products we use and order come in drums. Grease is the only one so far, that i know of, That comes with a liner. Why?
In: Chemistry
This is just a guess: you probably use suction to draw the grease up into grease guns etc so the liner pulls up with the product so you get all the grease out. Maybe because it doesn’t flow down to the bottom of the barrel like oil, paint, etc. Those more fluid products likely use a pump that has a wand that extends to the bottom of the barrel.
Let’s see if anyone else knows for sure!
