A novel adhesive system is introduced, featuring a 100% biodegradable, food-safe, UV-curable, and self-renewing composition. It requires no premixing and integrates nanomaterial reinforcement agents, biopolymer matrix components, crosslinking agents, and natural antioxidants. This adhesive offers adjustable tensile strengths from approximately 15 psi to 21,525.9 psi and maintains antimicrobial properties. It is wash-reactivatable, retaining effectiveness after 300-350 wash cycles, and tolerates temperatures from 40°C to 220°C. Meeting FDA/EFSA standards, it is hypoallergenic for prolonged skin contact.
The adhesive has multifaceted applications across various industries. It enhances knot security in shoelaces, offers reusable performance for food packaging, and enables layered tape solutions in automotive and aerospace sectors. Additionally, it provides biodegradable bonding for medical devices and consumer goods. This composition addresses the need for long-term, environmentally friendly adhesion without compromising performance.
Integrated into a shoelace system, the adhesive enhances functionality by improving knot security and facilitating the learning process through color-coded applications. A self-renewing, non-toxic shoelace system includes adhesive tabs positioned along each lace to guide the knot-tying process. Base adhesive tabs secure the initial knot while loop tabs assist in forming loops. Color-coded tabs simplify use, especially for children or beginners.
The shoelace system aids in developing fine motor skills and cognitive abilities. Conventional shoelaces often come untied or lack educational aspects for beginners. The adhesive provides increased friction between lace surfaces when tied, reducing the likelihood of knots coming undone. By offering visual and tactile cues, it promotes independence and confidence among users.
Fully biodegradable and washable, the shoelace system reduces environmental impact while promoting long-term use without performance degradation. The adhesive's self-renewing properties ensure durability even after extensive washing cycles. This innovative approach effectively addresses unmet needs in shoelace design and adhesive technology while supporting sustainability.
