SEOIL invented the extendable U-straw to eliminate the size limitation of the I-straw and thus revolutionized the drinking straw market
U-straws are more convenient to use, and they have universal shelf appeal. SEOIL can supply correctly dimensioned U-straws for all shapes and sizes of single portion liquid packaging.
Several diameters are available for various liquid thicknesses. SEOIL also developed heavier walled U-straws, the BENDA-straws, for easier penetration of more robust packaging.
