Considering the demanding of high quality paper straws by some of our clients from Korean and Japan, RainbowBear exclusively developed and produced the 4 layer paper straws. The 4 layer paper straws are thicker and of more weight than traditional 3 layer paper straws. For a straw size of 197x6mm, the 3 layer paper straws weighs 1.2gsm, while the 4 Layer paper straws weights 1.7gsm, the 4 layer’s are 42% heavier than 3 layer’s. The obviously result is that 4 Layer straws are much sturdy and holding up in water much longer time than 3 layer straws. If your clients are complaining on your easily soggy paper straws, you may as well try our 4 layer paper straws!
