New generation of adhesives enables growing demand for paper straws
H
B Fuller launches a new generation of high-performance adhesives with Swift tak 5730 grade to create consumer-safe, liquid-resistant paper straws, designed for fast-moving machines and improved sustainability.
As global regulatory single-use plastics bans come into effect across the globe, and the EU paves the way for the rest of the world by sealing a ban on throwaway plastics, such as plates, cutlery, and straws by mid-2021, manufacturers need a high-performance adhesive they can rely on to meet growing demand for paper straws.
According to research commissioned by HB Fuller, the Compound Annual Growth Rate (CAGR) for paper straws in Europe is expected to grow at 31% for the next three years. This estimate, combined with the upcoming sweeping legislations, reinforces sustainability as one of the guiding themes on strategy and product development for industry’s major players.
A multidisciplinary team of HB Fuller scientists has developed Swift tak 5730 water-based adhesive to further advance the paper straw industry. This technology offers paper straw producers superior performance in terms of consistent, easy machinability, cleanability, and overall productivity in response to the increased demand for safe and sustainable paper straws. The new generation of plasticiser-free, three-hour liquid resistant adhesive, which exceeds the liquid resistance market requirement for cold beverages, enables a high-quality durable straw and reduces operational downtime. In fact, its high wet tack allows manufacturers to meet aggressive productivity goals, while using fast paper straw machines that can produce more than 500 straws per minute.
Swift tak 5730 gives a competitive advantage for core winding and slot nozzle application for straight or bendy cold drink straw production, like those often used in
juice boxes. This adhesive comprises less than 5% of the total dried weight of a paper straw—enabling paper straws to be recycled and / or industrially composted. This technology allows paper straws to be compliant with German Federal Institute for Risk Assessment (BfR) Food-Contact Recommendation BfRXXXVI (Paper and Board for Food Contact Materials) for food contact to ensure maximum consumer safety. Although not legal norms, the the BfR recommendations are widely respected throughout the EU.
