What is gummed paper tape?

The gummed paper tape is a long fiber Kraft paper strip on which a natural, water-activated potato starch-based adhesive solution is provided, which gives it the property of adhering by capillary action to the surfaces of the boxes cardboard, until they merge and unify with them in a single safe and resistant packaging.

We produce at IBERGUM different kind of water activated tapes, a complete range that respond to all the variety of our clients' needs, all over the five continents.

Kraft Brown gummed paper

 Our clients use it for their most common shipments on brown packaging support, and for the reinforcement of cardboard boxes that are already used but still valid, prolonging their useful life. Reusing is one way to take responsibility for our relationship with the environment and one of the 4Rs… Kraft Brown gummed paper has a great resistance capacity and we manufacture it in different widths, diameters and weights. Due to its external appearance, we distinguish two types:

  • Kraft Brown unribbed, with the appearance of the sheet as it is produced in the paper machine.
  • Kraft Brown ribbed, characterized by a pattern of intersecting lines that forms the cylindrical mold that is used in its creation, or through a watermark, which gives it an elaborate texture and a refined and elegant finish. The use of  Kraft Brown ribbed water activated tape is widespread because it always enhances the presentation of a package. It is also used in bookbinding and fine arts.

Both references have the same technical characteristics and the differences are purely aesthetic depending on the taste of the consumer in each geographic market.

Some of our clients prefer it for aesthetic reasons in the printing of their logos and slogans.
