Double-sided tape is a type of adhesive tape that has adhesive on both sides, allowing it to stick to two surfaces simultaneously. It is commonly used for mounting, crafting, and repairs, providing a clean and neat appearance without visible tape edges. This tape comes in various widths and strengths, making it suitable for different applications, from lightweight paper to heavier materials. It is often used in offices, homes, and schools for tasks like hanging pictures or securing items together without the need for nails or glue.
