It is a neutral paper material that supports and holds your work together for framing. It is especially recommended for heavy paper and large papers that can not be supported by only corner supports. The non-adhesive side is applied to the mat along the blue line to prevent glue on the artwork, and the non-adhesive backing firmly supports the work with the mat and the adhesive side firmly supports the work with the spring. In particular, large pieces are set with appropriate length according to the length of each 4 sides of the artwork to eliminate sagging and unelision. When you want to add extra support strength, you can set the 2 layers at a point to make it more effective.
