AI Technical Summary
Existing double-sided tapes are either too thick or too thin, resulting in insufficient adhesive strength, making them unsuitable for use in confined spaces.
An ultra-thin, high-adhesion double-sided tape was designed. By setting first and second protrusions on both sides of the base layer and setting a reinforcement mechanism at the protrusions, including reinforcement blocks and micro grooves, the connection strength between the adhesive layer and the base layer is enhanced.
It achieves increased adhesiveness while maintaining thinness, enhances the bond strength with the object being adhered to, and prevents detachment.
