We believe in testing all our products to our own as well as industry standards. This is to make sure all our products are best in the market for how and why they are used.
Paper straws are tested against:
Liquid absorption of different acidities and sugars
Strength and diameter testing
Durability with contact to varying liquids
Ink leakage into liquid after set periods of time
We strive to make sure that our straws that enter the market match the level of quality we expect from all Utopia products.
