Which is better for the environment: water-activated paper tape or self-adhesive paper tape?

Gummed tape, also known as water-activated tape, is an adhesive tape manufactured from starch that is renewable, recyclable, and biodegradable. The starch-based adhesive on water-activated tapes seems dry and non-adhesive until it comes into contact with water, at which point it becomes super-sticky and may be put onto the desired surface, such as boxes or envelopes, for the ultimate sealing effect. The top layer of kraft paper on self-adhesive paper tape has a polymer-based release coating, while the bottom layer has a hot melt adhesive. Although it is far from the truth, this multi-layered substrate tape is promoted as a green alternative to plastic tapes.
