An Organic Solution for a Sticky Situation

Whether used in large-scale commercial use or in households, adhesive tape is a commonly used tool used in many different situations. The inspiration for this project came from the excess waste created when adhesive tapes are thrown into the garbage. This problem was addressed by creating and testing new rapidly biodegrading pressure-sensitive adhesive tapes. They would have properties like cellophane or cellulose acetate tape but would not be composed of any synthetic materials. These new adhesive tapes were created by testing naturally sticky substances and glues as the adhesives. They also had strong biodegradable materials as backings. There were two primary tests that were conducted: the test of peel adhesion and the test of tensile strength. The peel adhesion test helped determine the effectiveness and stickiness of each adhesive, while the tensile strength test helped determine the strength of the backing with an adhesive attached to it.

The results of the newly created tapes were compared to Scotch tape, painter’s tape, and paper storage tape. This helped to determine the ideal backing and adhesive for a new biodegradable adhesive tape, and how it would compare to the tapes in current usage. From the results, it was concluded that the rice flour adhesive was the stickiest of the newly created biodegradable adhesives. It was also concluded that honey on a banana leaf backing had the most tensile strength out of those tapes. As a final product, a combination of a rice flour adhesive attached to a banana leaf backing, with a primer of honey between them, was determined to be the ideal composition of the new tape.
