Description

<p>It was said that 2018 was the first year of the ocean disposal plastic issue movement. A lot of industries have started to disuse plastics and nations have prohibited to disposal plastics from 2018.</p><p>Nippon Paper Industries（NPi） set up new department “Paperising Promotion Office” in August 2018 in order to tackle the issue with paper. Paper straws are one of the paperising product. During the development of paper straws, it was found that conventional paper straws which were sold in Japan had some concerns about quality and feeling of use. The quality represented by water resistance and the feelings of use by using paper and adhesives are inferior to plastic straws. They stick to lips when we put them into mouth because of the moisture absorption. Smells and tastes of paper inhibit the flavor of beverages.</p><p>Paper straws pf NPi are used very high density and smoothness basepaper for outside layer to mouth feel in order to solve the concerns of taste, smell and sticking to the lips. Water resistance and safety concerns are solved by using paper that is strictly controlled in terms of hygiene and an adhesive compatible with food-safety laws. Moreover, the adhesive is selected to have high water resistance and almost no elution in water. Paper straws of NPi designed as described above has performance and safety comparable to plastic straws.</p><p>NPi’s Paper straws have been available for sale in April 2019, and currently on sale at the online shopping site of ASKUL. In addition, they were adopted for the first time in the food and beverage industry in June, and are used in multiple restaurants.</p>
