2025-08-15 Structure of Adhesive Tape
Adhesive tape is mainly composed of four parts: substrate, adhesive, release paper (film), and primer. 1. Substrate: This is the “skeleton” of the tape, providing basic physical strength for the tape. Common substrates include various materials, such as BOPP (biaxially oriented polypropylene film), which has high transparency, good tensile strength, and water resistance. It is widely used in ordinary packaging tapes to provide stable protection during the bundling process; PET (polyester film) material has excellent high temperature resistance and chemical corrosion resistance, and is commonly used in the field of electronics and electrical appliances to ensure stable performance of adhesive tape in complex environments, such as circuit board fixation, which often relies on it. 2. Adhesive: It can be called the “soul” of adhesive tape, responsible for achieving the adhesive function of the tape. According to its chemical composition, it can be divided into rubber type adhesives, which have strong adhesion and good initial adhesion, and have excellent adhesion effects on various material surfaces. They are mostly used for pasting paper packaging; Acrylate adhesive has good weather resistance and anti-aging performance, which can be used in outdoor logo pasting, automobile assembly and other scenes, and can remain firmly stuck even...
