This is a very interesting question from Types of Paper in portion Paper and Paper Based Packaging Materials of Food Packaging Technology

Answer 1

The correct option is (c) Kraft paper

To explain I would say: Kraft paper is typically coarse with exceptional strength, often made on a Fourdrinier machine and then either machine-glazed on a Yankee dryer or machine-finished on a calender. It is sometimes made with no calendering so that when it is converted into bags, the rough surface will prevent them from sliding over one another when stacked on pallets.
