Adhesive tape with different adhesive forces on two sides and bulletin board using adhesive tape

The present invention relates to an adhesive tape having different adhesive forces on both sides, and a bulletin board using the same, as an adhesive tape for attaching a post to an object by an adhesive force, comprising: a first surface attached to the object by a first adhesive force; and a second surface having a second adhesive force weaker than the first adhesive force and for attaching the post. Through the structure, the first face with strong adhesive force is attached to an object through the adhesive tape with different adhesive force on the two faces, and the post is attached to the second face with weak adhesive force, so that the post display device has the effect of being capable of being attached to various objects to display the post. 本发明涉及一种双面具有不同粘合力的胶带及使用该胶带的公告板，作为用于通过粘合力将帖子附着到物体上的胶带，其中，包括：第一面，通过第一粘着力贴附于所述物体上；以及第二面，具有比所述第一粘合力弱的第二粘合力，并且用于付着所述帖子。通过该结构，具有强粘合力的第一面通过双面具有不同粘合力的胶带贴附到物体上，并且在粘合力较弱的第二面上贴附帖子，从而具有能够贴附在各种物体上来展示帖子的效果。
