WIPO Patent Application WO/2021/015556
Kind Code:
A1
Abstract:
The present invention pertains to an adhesive composition in which natural materials such as starch are added to a cellulose solution; and a method for producing same. Since the adhesive composition is water separable and biodegradable, even while having excellent adhesion, labels as well as the adhesive can be completely removed from adherends during the regeneration of PET bottles by bringing the labels into contact with pure water without performing an alkaline water (lye) treatment. Thus, the adhesive composition has the advantage of being able to provide highly pure, high-quality recycled PET, and can simplify the regeneration process of PET due to being easily removed from PET bottles. In addition, the use of caustic soda is eliminated, and thus water pollution caused by washing water can be prevented. Also, the adhesive composition is an eco-friendly invention which when released, poses no risk of secondary environmental pollution, and which improves the physical properties of soil and has a deodorizing effect.
