The lids of average drink cup lids which has the straw slot were also changed to "sip lids" and were made of PE material. Although the amount of plastic used in the lids is less than plastic straws, not every "Single sip cup lid" can achieve plastic reduction goals. As long as the amount of plastic used in the beaker is 0.32 to 0.88 grams more than that of the straw, it may be replaced and the result may not decrease but increase. We found that if we can use origami techniques to replace the function of the cup lids and take advantage of the characteristics of paper, we can also customize the design and beautify the cup.
