Splicing tape and regular tape differ primarily in their intended use, adhesive properties, and material composition. 
Splicing tape is specifically designed for joining two ends of materials, such as film, paper, or fabric, during production processes. It is engineered to provide a seamless, durable bond that can withstand mechanical stress and environmental conditions. Splicing tapes often have a high-temperature resistance, making them suitable for processes involving heat, such as in the paper and printing industries. They are typically double-sided, allowing for a strong bond between two surfaces, and are available in various colors to aid in visibility and alignment during application.
Regular tape, on the other hand, is a more general-purpose adhesive tape used for everyday tasks like sealing, packaging, or temporary repairs. It includes a wide range of products such as masking tape, duct tape, and cellophane tape, each with different adhesive strengths and material compositions. Regular tapes are usually single-sided and are not designed to withstand the same level of stress or environmental conditions as splicing tapes. They are often made from materials like plastic, paper, or fabric, with adhesives that may not be suitable for high-temperature or high-stress applications.
In summary, the key differences lie in their specific applications, adhesive strength, temperature resistance, and material composition, with splicing tape being specialized for industrial use and regular tape serving more general, everyday purposes.
