Wow paper to STONE bag

  I just receive a bag from my aunt, it seems nothing special, but after I observed a paragraph of description under the 'paper bag'... Wow, it is incredible that the bag is made from tree-free paper. I dropped my cheek in a second. How can it be?

  The bag is made of stone powder. Calcium carbonate (CaCO₃) is the main material of manufacturing the bag. To become more durable, CaCO₃ would combine with high density polyethylene (HDPE). It is an environmental-friendly bag as it can be decomposed under UV light, it also printed using non-toxic inks.

  It feels like a plastic coating is coated on the surface. It is so special that I even can't delineate its texture. Besides, the appearance of the stone bag is nothing different with a actual paper bag.
 
  It's interesting, right? I love observing things in my daily lives and finding out the principle of the item that fascinating me. How about you? Feel free to put your feelings or comments down below. :)
