一，What is adhesive tape: Refers to all the tape-shaped films that can be pasted by a certain method: such as pressure, heating and so on.

二，The quality of the tape: There is no certain standard for the quality of the tape. Any tape that meets customer needs is a good tape.

三，Tape quality: The quality of the tape is maintained at a certain specification, and its quality is both excellent.

四，Classification of adhesive tape:

1. According to the structure: such as single-sided tape, double-sided tape, etc .;

2. According to the adhesive system: such as acrylic tape, rubber tape, silicone tape, etc .;

3. Classified by type: such as industrial tape, electronic tape, medical tape, etc .;

五，the composition of the tape:

1. Base material: such as paper, cloth, film, etc .;

2. Support: such as release paper, release film, etc .;

3. Adhesives: such as acrylic adhesives, rubber-based adhesives;

Remarks: The focus of physical property testing of substrates and supports are basis weight, thickness, tensile strength, elongation, and release force; the focus of physical property testing of adhesives is the solid components of viscosity.
六，The physical properties of the tape are coated amount, coating thickness, adhesion, retention, adhesion from the back, extraction force, initial adhesion, weather resistance, heat resistance, solvent resistance, electrical conductivity, flame resistance, etc.
