Adhesive for tapes, labels, envelopes, and similar applications required noncurling ability and they should be nonblocking under humid conditions. Certain tape and label adhesive also must be capable of rewetting or remoistening. This generally requires that the formulation contain acid modified starch or high soluble white and yellow dextrins to allow high solids contents. A formulation for a remoistening adhesive that is often used for envelopes is given in the table above.
