Abstract: The present invention addresses the problem of providing; a water absorbent resin powder having a reduced amount of fine powder generated and a reduced amount of fine powder recovered; and a production method for the water absorbent resin. The production method of the present invention includes a drying step and a fine powder granulation step. The drying step is for obtaining a dried polymer by drying a particulate water-containing gel crosslinked polymer which is obtained using an acid group-containing unsaturated monomer as a main component. The fine powder granulation step is for obtaining a fine powder granulated product by adding a binder and an adhesion control agent to a fine powder made of a water absorbent resin. In this production method, the obtained fine powder granulated product is recovered in the drying step or in any step before the drying step.

Abstract: Adhesive tape rolls having detackified side faces are presented, and methods of their manufacture. In one embodiment, the method comprises applying one or more inks to a side face of an adhesive tape roll with an ink jet printing system. In some embodiments, inks are applied in an image-wise manner so as to create a pattern, text or graphics, which may include: barcodes. QR codes, brand information, manufacturing information, or remaining roll quantity indicia. In one aspect, the present methods enable elimination of packaging materials by two concurrent advantages: a) detackifying the side faces, which eliminates the need for packaging materials to prevent blocking of stacked rolls and accumulation of debris on side faces; and b) producing an adhesive tape roll bearing text, graphics, or other information on the side face of the roll, which eliminates the need for packaging materials to bear such information.
