The composition of the tape is divided into glue and film. If the smell of the glue is relatively strong, then the glue should not be pure glue. It contains additives. The smell produced by the tape will volatilize, so it will not be harmful to the human body.
Adhesive tape is composed of two parts, base material and adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used.
Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive has various polymers according to different brands and types.

The main hazard is glue, but not all glues are harmful. Glue is mainly divided into water-based and oil-based, and water-based glue is generally harmless because the diluent is water. But oil-based glue is relatively more harmful, because its diluent is mainly formazan, which is a volatile and dangerous chemical, which will damage the liver function after inhalation. If the dosage of tape produced by a regular manufacturer meets the standard, it is generally safe and there will be no major problems.
