How do Paper Straws not Get Soggy?

Welcome to the world of sustainable sipping! As the world awakens to the environmental toll of plastic straws, the shift toward sustainable alternatives becomes imperative.

However, amidst this eco-revolution, concerns have arisen about the quality of plastic straw replacements, particularly the ever-popular paper straws. Ever wondered why do paper straws get soggy? Our investigation into this common concern, along with insights into their longevity and innovative solutions for preventing sogginess, provides a comprehensive guide to making eco-friendly choices in the realm of single-use plastics. Let's sip sustainably and explore the fascinating world of paper straws!

What are Paper Straws Made of?

Typically crafted from food-grade paper, inks, and other raw materials, paper straws boast durability during use while easily composting once recycled or disposed of. The manufacturing process resembles familiar tube winding techniques used in various products like paper towel rolls and shipping tubes. In this process, thin reels of paper are coated in glue, wound together to form lengthy cylinders, and then cut, packaged, and shipped, offering a practical and environmentally conscious solution to single-use plastic straws.

Why do Paper Straws Get Soggy?

The shift towards environmentally friendly alternatives has propelled the popularity of paper straws, emerging as a primary replacement for their plastic counterparts. However, a common concern that often arises is the inevitable softening of paper straws, prompting the question——why do paper straws get soggy? The fundamental reason lies in the inherent absorbent quality of paper. Unlike their plastic counterparts, paper straws readily absorb moisture from the beverages they come into contact with, initiating a gradual breakdown of the material. This absorbency is particularly noticeable when exposed to liquids for an extended period, and it becomes more pronounced with hot or acidic drinks. While strides have been made in improving the durability of paper straws, understanding the science behind their potential softening is essential for both consumers and brands aiming to provide an optimal user experience. Addressing this concern not only ensures customer satisfaction but also propels ongoing innovations in the realm of eco-friendly alternatives, contributing to a more sustainable future.

How Long does a Paper Straw Last in a Drink Before it Gets Soggy?

The longevity of a paper straw in a drink before it turns soggy is a common concern for those making the switch from plastic. The duration largely depends on factors such as the thickness of the paper, the type of beverage, and how it's used. In general, paper straws are designed to last for about 1 to 3 hours in a cold beverage, but this timeframe can be shorter when dealing with hot or acidic drinks. The absorbent nature of paper makes it susceptible to moisture, and prolonged exposure accelerates the softening process.

The quest for eco-friendly and non-soggy paper straws has led to innovative developments in materials and manufacturing processes. Traditional paper straws often become inconvenient to use due to their tendency to turn soggy upon prolonged contact with liquids, impacting user experience. So how do paper straws not get soggy? To address this issue, the joint research team of Dr. Oh Dongyeop and Dr. Kwak Hojung of KRICT, along with Professor Park Jeyoung of Sogang University, has successfully developed 100% biodegradable paper straws. Unlike conventional counterparts, these eco-friendly straws are coated with a specially synthesized biodegradable plastic, polybutylene succinate (PBS), which includes cellulose nanocrystals—the same material as the main component of paper. This coating enhances durability, prevents sogginess, and ensures a prolonged lifespan. The research team's groundbreaking technology not only outperforms conventional paper and corn plastic straws but also addresses environmental concerns by decomposing more than 50% of their weight after 60 days under marine conditions, offering a promising solution to the drawbacks of existing alternatives.


In conclusion, exploring the world of paper straws reveals their eco-friendly composition and the ongoing efforts to address challenges such as sogginess. Innovations like 100% biodegradable paper straws, coated with a specially synthesized plastic, showcase promising solutions. These advancements reflect a commitment to performance and environmental responsibility, making paper straws a compelling choice in reducing our reliance on single-use plastics.
