Rendering's Gold Label Leaf Lard, Pasture Raised, Bright White, Neutral Flavor Lard for Baking, Cooking & Frying, 14 oz jar

I've noticed some differences in labeling on products. What is the difference in pure "leaf" lard and pure lard? Or is there a difference?

Hello, is the container glass. is this leaf or back fat? is this lard processed in any way? thank-you

What country is the source for the pork fat from which this lard is rendered?

Who is the manufacturer? I can't find Renderings online. Is there a website?
