Question

Name the types of paper having the following properties and mention one use of each.
(I) Porous and semi-permeable.
(II) Nonsticky property.

Answer 1

Hint: Paper is a thin sheet material made by mechanically or chemically processing cellulose fibers from wood, rags, grasses, or other vegetable sources in water, then draining the water through a fine-mesh to leave the fiber evenly distributed on the surface, pressing, and drying.

Complete answer: Although the paper was once made by hand in single sheets, it is now almost entirely produced by large machines, some of which produce reels 10 meters wide, run at 2,000 meters per minute, and produce up to 600,000 tonnes per year.
It has a wide range of applications, including printing, packaging, decorating, writing, cleaning, filter paper, wallpaper, book endpapers, conservation paper, laminate worktops, toilet tissue, currency and security paper, and several industrial and construction processes.
Porous and semi-permeable: A filter paper is a porous piece of paper used to filter liquids, particularly in chemical processes. It's a semi-permeable paper barrier that's placed perpendicular to the flow of liquid or air.

Non Sticky property: Waxed paper (also known as wax paper or paraffin paper) is a type of paper that has been treated with wax to make it water-resistant.
Oiling parchment or paper to make it semi-translucent or moisture-proof dates back to the Middle Ages at the very least. Throughout the nineteenth century, paper impregnated or coated with purified beeswax was widely used to retain or exclude moisture, or to wrap odorous items.
Thus,
(I) Porous and semi-permeable: filter paper
(II) Nonsticky property: Wax paper

Note: The most common fiber source before the industrialization of paper production was recycled fibers from used textiles, known as rags. Hemp, linen, and cotton were used to make the rags. In 1774, German jurist Justus Claproth invented a method for removing printing inks from recycled paper. This process is now known as drinking.
