Glues
Glue is a type of solvent used to stick 2 objects together. It is often used as an adhesive for paper, such as pasting receipts to a notebook or sealing an envelope. There are also products that can be used for fabric, wood, rubber, plastic and so on, depending on the adhesive strength and property of the glue. Various types of glue are available, including products in a container that requires a spatula to take out the glue, glue sticks that come in a container like a lipstick, tape glue and spray glue, all designed to enable use without dirtying your hands. Colored glue is useful for ensuring glue is applied evenly. There is also re-stickable-type glue that can be used for tacking and peeling off later. Most glue is made of PGE or other material derived from natural sources such as potatoes. Some glue is made as low-acid as possible so as not to change the quality of the paper.
